-+++
-** Etags command line option '--declarations' now has Mercury-specific 
behavior.
-All Mercury declarations are tagged by default.  However, for
-compatibility with 'etags' support for Prolog, predicates and
-functions appearing first in clauses will also be tagged if 'etags' is
-invoked with the '--declarations' command-line option.
+** The new NonGNU ELPA archive is enabled by default alongside GNU ELPA.
 
 +++
-** New command 'font-lock-update', bound to 'C-x x f'.
-This command updates the syntax highlighting in this buffer.
+** New command 'execute-extended-command-for-buffer'.
+This new command, bound to 'M-S-x', works like
+'execute-extended-command', but limits the set of commands to the
+commands that have been determined to be particularly useful with the
+current mode.
 
 +++
-** A new standard face 'font-lock-doc-markup-face'.
-Intended for documentation mark-up syntax and tags inside text that
-uses 'font-lock-doc-face', with which it should harmonise.  It would
-typically be used in structured documentation comments in program
-source code by language-specific modes, for mark-up conventions like
-Haddock, Javadoc or Doxygen.  By default this face inherits from
-'font-lock-constant-face'.
-
-** The new NonGNU ELPA archive is enabled by default alongside GNU ELPA.
+** New user option 'read-extended-command-predicate'.
+This user option controls how 'M-x' performs completion of commands when
+you type 'TAB'.  By default, any command that matches what you have
+typed is considered a completion candidate, but you can customize this
+option to exclude commands that are not applicable to the current
+buffer's major and minor modes, and respect the command's completion
+predicate (if any).
 
 +++
-** New command 'recenter-other-window', bound to 'S-M-C-l'.
-Like 'recenter-top-bottom' acting in the other window.
+** When 'suggest-key-bindings' is non-nil, the completion list of 'M-x'
+shows equivalent key bindings for all commands that have them.
 
-** Minibuffer scrolling is now conservative by default.
-This is controlled by the new variable 'scroll-minibuffer-conservatively'.
+** New user option 'completions-detailed'.
+When non-nil, some commands like 'describe-symbol' show more detailed
+completions with more information in completion prefix and suffix.
 
-In addition, there is a new variable
-'redisplay-adhoc-scroll-in-resize-mini-windows' to disable the
-ad-hoc auto-scrolling when resizing minibuffer windows.  It has been
-found that its heuristic can be counter productive in some corner
-cases, tho the cure may be worse than the disease.  This said, the
-effect should be negligible in the vast majority of cases anyway.
+---
+** 'C-s' in 'M-x' now searches over completions again.
+In Emacs 23, typing 'M-x' ('read-extended-command') and then 'C-s' (to
+do an interactive search) would search over possible completions.
+This was lost in Emacs 24, but is now back again.
 
-+++
-** Improved handling of minibuffers on switching frames.
-By default, when you switch to another frame, an active minibuffer now
-moves to the newly selected frame.  Nevertheless, the effect of what
-you type in the minibuffer happens in the frame where the minibuffer
-was first activated.  An alternative behavior is available by
-customizing 'minibuffer-follows-selected-frame' to nil.  Here, the
-minibuffer stays in the frame where you first opened it, and you must
-switch back to this frame to continue or abort its command.  The old
-behavior, which mixed these two, can be approximated by customizing
-'minibuffer-follows-selected-frame' to a value which is neither nil
-nor t.
+---
+** User option 'completions-format' supports a new value 'one-column'.
 
 +++
-** New user option 'read-minibuffer-restore-windows'.
-When customized to nil, it uses 'minibuffer-restore-windows' in
-'minibuffer-exit-hook' to remove only the window showing the
-"*Completions*" buffer.
+** A new keymap for buffer actions has been added.
+The 'C-x x' keymap now holds keystrokes for various buffer-oriented
+commands.  The new keystrokes are 'C-x x g' ('revert-buffer-quick'),
+'C-x x r' ('rename-buffer'), 'C-x x u' ('rename-uniquely'), 'C-x x n'
+('clone-buffer'), 'C-x x i' ('insert-buffer'), 'C-x x t'

+** New minor mode 'context-menu-mode' for context menus popped by 'mouse-3'.
+When this mode is enabled, clicking 'down-mouse-3' anywhere in the buffer
+pops up a menu whose contents depends on surrounding context near the
+mouse click.  You can change the order of the default sub-menus in the
+context menu by customizing the user option 'context-menu-functions'.
+You can also invoke the context menu by pressing 'S-<F10>'.
+
++++
+** Modifiers now go outside angle brackets in pretty-printed key bindings.
+For example, 'RET' with Control and Meta modifiers is now shown as
+'C-M-<return>' instead of '<C-M-return>'.  Either variant can be used
+as input; functions such as 'kbd' and 'read-kbd-macro' accept both
+styles as equivalent (they have done so for a long time).

-** Improved "find definition" feature of "*Help*" buffers.
-Now clicking on the link to find the definition of functions generated
-by 'cl-defstruct', or variables generated by 'define-derived-mode',
-for example, will go to the exact place where they are defined.
+** 'eval-expression' no longer signals an error on incomplete expressions.
+Previously, typing 'M-: ( RET' would result in Emacs saying "End of
+file during parsing" and dropping out of the minibuffer.  The user
+would have to type 'M-: M-p' to edit and redo the expression.  Now
+Emacs will echo the message and allow the user to continue editing.
 
-** New variable 'redisplay-skip-initial-frame' to enable batch redisplay tests.
-Setting it to nil forces the redisplay to do its job even in the
-initial frame used in batch mode.
++++
+** 'eval-last-sexp' now handles 'defvar'/'defcustom'/'defface' specially.
+This command would previously not redefine values defined by these
+forms, but this command has now been changed to work more like
+'eval-defun', and reset the values as specified.
 
 ---
-** Support for the 'strike-through' face attribute on TTY frames.
-If your terminal's termcap or terminfo database entry has the 'smxx'
-capability defined, Emacs will now emit the prescribed escape
-sequences necessary to render faces with the 'strike-through'
-attribute on TTY frames.
+** New user option 'use-short-answers'.
+When non-nil, the function 'y-or-n-p' is used instead of
+'yes-or-no-p'.  This eliminates the need to define an alias that maps
+one to another in the init file.  The same user option also controls
+whether the function 'read-answer' accepts short answers.
 
 +++
-** Emacs now defaults to UTF-8 instead of ISO-8859-1.
-This is only for the default, where the user has set no 'LANG' (or
-similar) variable or environment.  This change should lead to no
-user-visible changes for normal usage.
+** New user option 'kill-buffer-delete-auto-save-files'.
+If non-nil, killing a buffer that has an auto-save file will prompt
+the user for whether that file should be deleted.  (Note that
+'delete-auto-save-files', if non-nil, was previously documented to
+result in deletion of auto-save files when killing a buffer without
+unsaved changes, but this has apparently not worked for several
+decades, so the documented semantics of this variable has been changed
+to match the behaviour.)
 
 +++
-** New variables that hold default buffer names for shell output.
-The new constants 'shell-command-buffer-name' and
-'shell-command-buffer-name-async' store the default buffer names
-for the output of, respectively, synchronous and async shell
-commands.
+** New user option 'next-error-message-highlight'.
+In addition to a fringe arrow, 'next-error' error may now optionally
+highlight the current error message in the 'next-error' buffer.
+This user option can be also customized to keep highlighting on all
+visited errors, so you can have an overview what errors were already visited.
 
-** Support for '(box . SIZE)' 'cursor-type'.
-By default, 'box' cursor always has a filled box shape.  But if you
-specify 'cursor-type' to be '(box . SIZE)', the cursor becomes a hollow
-box if the point is on an image larger than SIZE pixels in any
-dimension.
+---
+** New choice 'next-error-quit-window' for 'next-error-found-function'.
+When 'next-error-found-function' is customized to 'next-error-quit-window',
+then typing the numeric prefix argument 0 before the command 'next-error'
+will quit the source window after visiting the next occurrence.
 
 +++
-** New user option 'word-wrap-by-category'.
-When word-wrap is enabled, and this option is non-nil, that allows
-Emacs to break lines after more characters than just whitespace
-characters.  In particular, this significantly improves word-wrapping
-for CJK text mixed with Latin text.
+** New user option 'file-preserve-symlinks-on-save'.
+This controls what Emacs does when saving buffers that visit files via
+symbolic links, and 'file-precious-flag' is non-nil.
+
++++
+** New user option 'copy-directory-create-symlink'.
+If non-nil, will make `copy-directory' (when used on a symbolic
+link) copy the link instead of following the link.  The default is
+nil, so the default behavior is unchanged.
+
++++
+** New user option 'ignored-local-variable-values'.
+This is the opposite of 'safe-local-variable-values' -- it's an alist
+of variable-value pairs that are to be ignored when reading a
+local-variables section of a file.
 
 ---
-** Rudimentary support for the 'st' terminal emulator.
-Emacs now supports 256 color display on the 'st' terminal emulator.
+** Specific warnings can now be disabled from the warning buffer.
+When a warning is displayed to the user, the resulting buffer now has
+buttons which allow making permanent changes to the treatment of that
+warning.  Automatic showing of the warning can be disabled (although
+it is still logged to the "*Messages*" buffer), or the warning can be
+disabled entirely.
+
++++
+** ".dir-locals.el" now supports setting 'auto-mode-alist'.
+The new 'auto-mode-alist' specification in ".dir-locals.el" files can
+now be used to override the global 'auto-mode-alist' in the current
+directory tree.
 
 ---
-** Mouse wheel scrolling now works on more parts of frame's display.
-When using 'mwheel-mode', the mouse wheel will now scroll also when
-the mouse cursor is on the scroll bars, fringes, margins, header line,
-and mode line.  ('mwheel-mode' is enabled by default on most graphical
-displays.)
+** User option 'uniquify-buffer-name-style' can now be a function.
+This user option can be one of the predefined styles or a function to
+personalize the uniquified buffer name.

-** Mouse wheel scrolling now defaults to one line at a time.
+** 'remove-hook' is now an interactive command.

 +++
-** Mouse wheel scrolling with Shift modifier now scrolls horizontally.
-This works in text buffers and over images.  Typing a numeric prefix arg
-(e.g. 'M-5') before starting horizontal scrolling changes its step value.
-The value is saved in the user option 'mouse-wheel-scroll-amount-horizontal'.
+*** The key prefix 'C-x 5 5' displays next command buffer in a new frame.
+It's bound to the command 'other-frame-prefix' that requests the buffer
+of the next command to be displayed in a new frame.

+*** The key prefix 'C-x 4 1' displays next command buffer in the same window.
+It's bound to the command 'same-window-prefix' that requests the buffer
+of the next command to be displayed in the same window.
 
-** 'redisplay-skip-fontification-on-input' helps Emacs keep up with fast input.
-This is another attempt to solve the problem of handling high key repeat rate

-** New user option 'lazy-highlight-no-delay-length'.
-Lazy highlighting of matches in Isearch now starts immediately if the
-search string is at least this long.  'lazy-highlight-initial-delay'
-still applies for shorter search strings, which avoids flicker in the
-search buffer due to too many matches being highlighted.
+*** New user option 'delete-window-choose-selected'.

-** A new keymap for buffer actions has been added.
-The 'C-x x' keymap now holds keystrokes for various buffer-oriented

-** New user option 'query-about-changed-file'.
-If non-nil (the default), users are prompted as before when
-re-visiting a file that has changed externally after it was visited

-buffer is opened with its contents before the change, and the user is
-given instructions how to revert the buffer.
+** Minibuffer
 
-+++
-** Improved support for terminal emulators that encode the Meta flag.
-Some terminal emulators set the 8th bit of Meta characters, and then
-encode the resulting character code as if it were non-ASCII character
-above codepoint 127.  Previously, the only way of using these in Emacs
-was to set up the terminal emulator to use the 'ESC' characters to send
-Meta characters to Emacs, e.g., send "ESC x" when the user types
-'M-x'.  You can now avoid the need for this setup of such terminal
-emulators by using the new input-meta-mode with the special value
-'encoded' with these terminal emulators.

-This user option controls how 'M-x' performs completion of commands when
-you type 'TAB'.  By default, any command that matches what you have
-typed is considered a completion candidate, but you can customize this
-option to exclude commands that are not applicable to the current
-buffer's major and minor modes, and respect the command's completion
-predicate (if any).
+---
+*** New command 'toggle-frame-tab-bar'.
+It can be used to enable/disable the tab bar individually on each frame
+independently from the value of 'tab-bar-mode' and 'tab-bar-show'.
 
 ---
-** 'eval-expression' now no longer signals an error on incomplete expressions.
-Previously, typing 'M-: ( RET' would result in Emacs saying "End of
-file during parsing" and dropping out of the minibuffer.  The user
-would have to type 'M-: M-p' to edit and redo the expression.  Now
-Emacs will echo the message and allow the user to continue editing.
+*** New user option 'tab-bar-format' defines a list of tab bar items.
+When it contains 'tab-bar-format-global' (possibly appended after
+'tab-bar-format-align-right'), then after enabling 'display-time-mode'
+(or any other mode that uses 'global-mode-string') it displays time
+aligned to the right on the tab bar instead of the mode line.
+When 'tab-bar-format-tabs' is replaced with 'tab-bar-format-tabs-groups',
+then the tab bar displays tab groups.
 
-+++
-** 'eval-last-sexp' now handles 'defvar'/'defcustom'/'defface' specially.
-This command would previously not redefine values defined by these
-forms, but this command has now been changed to work more like
-'eval-defun', and reset the values as specified.
+---
+*** 'Mod-9' bound to 'tab-last' now switches to the last tab.
+It also supports a negative argument.
 
-+++
-** Standalone 'M-y' allows interactive selection from previous kills.
-'M-y' can now be typed after a command that is not a yank command.
-When invoked like that, it prompts in the minibuffer for one of the
-previous kills, offering completion and minibuffer-history navigation
-through previous kills recorded in the kill ring.  A similar feature
-in Isearch can be invoked if you bind 'C-s M-y' to the command
-'isearch-yank-pop'.  When the user option 'yank-from-kill-ring-rotate'
-is nil the kill ring is not rotated after 'yank-from-kill-ring'.
+---
+*** New command 'tab-duplicate' bound to 'C-x t n'.
 
 ---
-** New user options 'copy-region-blink-delay' and 'delete-pair-blink-delay'.
-'copy-region-blink-delay' specifies a delay to indicate the region
-copied by 'kill-ring-save'.  'delete-pair-blink-delay' specifies
-a delay to show a paired character to delete.
+*** 'C-x t N' creates a new tab at the specified absolute position.
+It also supports a negative argument.
 
-+++
-** New command 'undo-redo'.
-It undoes previous undo commands, but doesn't record itself as an
-undoable command.
+---
+*** 'C-x t M' moves the current tab to the specified absolute position.
+It also supports a negative argument.
 
-+++
-** 'read-number' now has its own history variable.
-Additionally, the function now accepts a HIST argument which can be
-used to specify a custom history variable.
+---
+*** 'C-x t G' assigns a group name to the tab.
+'tab-close-group' can close all tabs that belong to the selected group.
+The user option 'tab-bar-new-tab-group' defines the default group of a
+new tab.  After customizing 'tab-bar-tab-post-change-group-functions'
+to 'tab-bar-move-tab-to-group', changing the tab group will also move it
+closer to other tabs in the same group.
 
-+++
-** Input history for 'goto-line' can now be made local to every buffer.
-In any event, line numbers used with 'goto-line' are kept in their own
-history list.  This should help make faster the process of finding
-line numbers that were previously jumped to.  By default, all buffers
-share a single history list.  To make every buffer have its own
-history list, customize the user option 'goto-line-history-local'.
+---
+*** New user option 'tab-bar-tab-name-format-function'.
 
-+++
-** New command 'goto-line-relative' to use in a narrowed buffer.
-It moves point to the line relative to the accessible portion of the
-narrowed buffer.  'M-g M-g' in Info is rebound to this command.
-When 'widen-automatically' is non-nil, 'goto-line' widens the narrowed
-buffer to be able to move point to the inaccessible portion.
-'goto-line-relative' is bound to 'C-x n g'.
+---
+*** New user option 'tab-line-tab-name-format-function'.
 
-+++
-** When called interactively, 'goto-char' now offers the number at
-point as default.
+---
+*** The tabs in the tab line can now be scrolled using horizontal scroll.
+If your mouse or trackpad supports it, you can now scroll tabs when
+the mouse pointer is in the tab line by scrolling left or right.
 
-+++
-** When 'suggest-key-bindings' is non-nil, the completion list of 'M-x'
-shows equivalent key bindings for all commands that have them.
+---
+*** New tab-line faces and options.
+The face 'tab-line-tab-special' is used for tabs whose buffers are
+special, i.e. not file-backed.  The face
+'tab-line-tab-inactive-alternate' is used to display inactive tabs
+with an alternating background color, making them easier to
+distinguish between, especially if the face 'tab-line-tab' is
+configured to not display with a box; this alternate face is only
+applied when the option 'tab-line-tab-face-functions' is
+so-configured.  That option may also be used to customize tab-line
+faces in other ways.
 
-** Autosaving via 'auto-save-visited-mode' can now be inhibited by
-setting the variable 'auto-save-visited-mode' buffer-locally to nil.
+** Mouse wheel
 
-** New commands to describe buttons and widgets have been added.
-'widget-describe' (on a widget) will pop up a help buffer and give a
-description of the properties.  Likewise 'button-describe' does the
-same for a button.
+---
+*** Mouse wheel scrolling now defaults to one line at a time.
 
-** Obsolete aliases are no longer hidden from command completion.
-Completion of command names now considers obsolete aliases as
-candidates, if they were marked obsolete in the current major version
-of Emacs.  Invoking a command via an obsolete alias now mentions the
-obsolescence fact and shows the new name of the command.
+---
+*** Mouse wheel scrolling now works on more parts of frame's display.
+When using 'mwheel-mode', the mouse wheel will now scroll also when
+the mouse cursor is on the scroll bars, fringes, margins, header line,
+and mode line.  ('mwheel-mode' is enabled by default on most graphical
+displays.)
 
 +++
-** New command 'revert-buffer-with-fine-grain'.
-Revert a buffer trying to be as non-destructive as possible,
-preserving markers, properties and overlays.  The new variable
-'revert-buffer-with-fine-grain-max-seconds' specifies the maximum
-number of seconds that 'revert-buffer-with-fine-grain' should spend
-trying to be non-destructive.
+*** Mouse wheel scrolling with Shift modifier now scrolls horizontally.
+This works in text buffers and over images.  Typing a numeric prefix arg
+(e.g. 'M-5') before starting horizontal scrolling changes its step value.
+The value is saved in the user option 'mouse-wheel-scroll-amount-horizontal'.
 
-+++
-** New command 'memory-report'.
-This command opens a new buffer called "*Memory Report*" and gives a
-summary of where Emacs is using memory currently.
+** Customize
 
-+++
-** New user option 'isearch-repeat-on-direction-change'.
-When this option is set, direction changes in Isearch move to another
-search match, if there is one, instead of moving point to the other
-end of the current match.
+---
+*** Customize buffers can now be reverted with 'C-x x g'.
 
-** Outline
+*** Most customize commands now hide obsolete user options.
+Obsolete user options are no longer shown in the listings produced by
+the commands 'customize', 'customize-group', 'customize-apropos' and
+'customize-changed'.
 
-+++
-*** New commands to cycle heading visibility.
-Typing 'TAB' on a heading line cycles the current section between
-"hide all", "subheadings", and "show all" states.  Typing 'S-TAB'
-anywhere in the buffer cycles the whole buffer between "only top-level
-headings", "all headings and subheadings", and "show all" states.
+To customize obsolete user options, use 'customize-option' or
+'customize-saved'.
 
-+++
-*** New user option 'outline-minor-mode-cycle'.
-This user option customizes 'outline-minor-mode', with the difference
-that 'TAB' and 'S-TAB' on heading lines cycle heading visibility.
-Typing 'TAB' on a heading line cycles the current section between
-"hide all", "subheadings", and "show all" states.  Typing 'S-TAB' on a
-heading line cycles the whole buffer between "only top-level
-headings", "all headings and subheadings", and "show all" states.
+*** New SVG icons for checkboxes and arrows.
+They will be used automatically instead of the old icons.  If Emacs is
+built without SVG support, the old icons will be used instead.
 
----
-*** New user option 'outline-minor-mode-highlight'.
-This user option customizes 'outline-minor-mode'.  It puts
-highlighting on heading lines using standard outline faces.  This
-works well only when there are no conflicts with faces used by the
-major mode.
+** Help
 
 +++
-** New commands 'copy-matching-lines' and 'kill-matching-lines'.
-These commands are similar to the command 'flush-lines',
-but add the matching lines to the kill ring as a single string,
-including the newlines that separate the lines.
-
-
-* Changes in Specialized Modes and Packages in Emacs 28.1
-
-** Completion List Mode
+*** New command 'describe-command' shows help for a command.
+This can be used instead of 'describe-function' for interactive
+commands and is globally bound to 'C-h x'.
 
-New key bindings have been added to 'completion-list-mode': 'n' and
-'p' now navigate completions, and 'M-g M-c' switches to the
-minibuffer and back to the completion list buffer.
++++
+*** New command 'describe-keymap' describes keybindings in a keymap.
 
-** Benchmark
-*** New function 'benchmark-call' to measure the execution time of a function.
-Additionally, the number of repetitions can be expressed as a minimal duration
-in seconds.
+*** New command 'apropos-function'.
+This works like 'C-u M-x apropos-command' but is more discoverable.
 
-** Macroexp
----
-*** New function 'macroexp-file-name' to know the name of the current file.
 ---
-*** New function 'macroexp-compiling-p' to know if we're compiling.
+*** New keybinding 'C-h R' prompts for a manual to display and displays it.
+
 ---
-*** New function 'macroexp-warn-and-return' to help emit warnings.
-This used to be named 'macroexp--warn-and-return' and has proved useful
-and well-behaved enough to lose the "internal" marker.
+*** Keybindings in 'help-mode' use the new 'help-key-binding' face.
+This face is added by 'substitute-command-keys' to any "\[command]"
+substitution.  The return value of that function should consequently
+be assumed to be a propertized string.
+
+Note that the new face will also be used in tooltips.  When using the
+GTK toolkit, this is only true if 'x-gtk-use-system-tooltips' is t.
 
-** Bindat
+---
+*** The 'help-for-help' ('C-h C-h') screen has been redesigned.
 
 +++
-*** New 'Bindat type expression' description language.
-This new system is provided by the new macro 'bindat-type' and
-obsoletes the old data layout specifications.  It supports
-arbitrary-size integers, recursive types, and more.  See the Info node
-"(elisp) Byte Packing" in the ELisp manual for more details.
+*** New convenience commands with short keys in the Help buffer.
+New command 'help-view-source' ('s') will view the source file (if
+any) of the current help topic.  New command 'help-goto-info' ('i')
+will look up the current symbol (if any) in Info.  New command
+'help-customize' ('c') will customize the variable or the face
+(if any) whose doc string is being shown in the Help buffer.
 
-** pcase
+---
+*** New user option 'describe-bindings-outline'.
+It enables outlines in the output buffer of 'describe-bindings' that
+can provide a better overview in a long list of available bindings.
 
 +++
-*** The 'or' pattern now binds the union of the vars of its sub-patterns.
-If a variable is not bound by the subpattern that matched, it gets bound
-to nil.  This was already sometimes the case, but it is now guaranteed.
+*** New command 'lossage-size'.
+It allows users to set the maximum number of keystrokes and commands
+recorded for the purpose of 'view-lossage'.
 
-+++
-*** The 'pred' pattern can now take the form '(pred (not FUN))'.
-This is like '(pred (lambda (x) (not (FUN x))))' but results
-in better code.
+*** New commands to describe buttons and widgets.
+'widget-describe' (on a widget) will pop up a help buffer and give a
+description of the properties.  Likewise 'button-describe' does the
+same for a button.
 
 ---
-*** New function 'pcase-compile-patterns' to write other macros.
+*** Improved "find definition" feature of "*Help*" buffers.
+Now clicking on the link to find the definition of functions generated
+by 'cl-defstruct', or variables generated by 'define-derived-mode',
+for example, will go to the exact place where they are defined.
 
-*** Added 'cl-type' pattern.
-The new 'cl-type' pattern compares types using 'cl-typep', which allows
-comparing simple types like '(cl-type integer)', as well as forms like
-'(cl-type (integer 0 10))'.
+*** New commands 'apropos-next-symbol' and 'apropos-previous-symbol'.
+These new navigation commands are bound to 'n' and 'p' in
+'apropos-mode'.
 
-*** New macro 'pcase-setq'
-This macro is the 'setq' equivalent of 'pcase-let', which allows for
-destructuring patterns in a 'setq' form.
+---
+*** The command 'view-lossage' can now be invoked from the menu bar.
+The menu bar "Help" menu now has a "Show Recent Inputs" item under the
+"Describe" sub-menu.
 
-+++
-** profiler.el
-The results displayed by 'profiler-report' now have the usage figures
-at the left hand side followed by the function name.  This is intended
-to make better use of the horizontal space, in particular eliminating
-the truncation of function names.  There is no way to get the former
-layout back.
+---
+*** Closing the "*Help*" buffer from the toolbar now buries the buffer.
+In previous Emacs versions, the "*Help*" buffer was killed instead when
+clicking the "X" icon in the tool bar.
 
-** Loading dunnet.el in batch mode doesn't start the game any more.
-Instead you need to do "emacs -f dun-batch" to start the game in
-batch mode.
+---
+*** 'g' ('revert-buffer') in 'help-mode' no longer requires confirmation.
 
-** Emacs Server
+** Miscellaneous
 
 +++
-*** New user option 'server-client-instructions'.
-When emacsclient connects, Emacs will (by default) output a message
-about how to exit the client frame.  If 'server-client-instructions'
-is set to nil, this message is inhibited.
+*** New command 'font-lock-update', bound to 'C-x x f'.
+This command updates the syntax highlighting in this buffer.
 
 +++
-*** New command 'server-edit-abort'.
-This command (not bound to any key by default) can be used to abort
-an edit instead of marking it as "Done" (which the 'C-x #' command
-does).  The 'emacsclient' program exits with an abnormal status as
-result of this command.
+*** New command 'memory-report'.
+This command opens a new buffer called "*Memory Report*" and gives a
+summary of where Emacs is using memory currently.
 
 +++
-*** New desktop integration for connecting to the server.
-If your operating system’s desktop environment is
-freedesktop.org-compatible (which is true of most GNU/Linux and other
-recent Unix-like GUIs), you may use the new "Emacs (Client)" desktop
-menu entry to open files in an existing Emacs instance rather than
-starting a new one.  The daemon starts if not already running.
-
-** Perl mode
+*** New command 'submit-emacs-patch'.
+This works like 'report-emacs-bug', but is more geared towards sending
+patches to the Emacs issue tracker.
 
----
-*** New face 'perl-non-scalar-variable'.
-This is used to fontify non-scalar variables.
+*** New face 'apropos-button'.
+Applies to buttons that indicate a face.
 
-** Python mode
++++
+*** New face 'font-lock-doc-markup-face'.
+Intended for documentation mark-up syntax and tags inside text that
+uses 'font-lock-doc-face', with which it should harmonise.  It would
+typically be used in structured documentation comments in program
+source code by language-specific modes, for mark-up conventions like
+Haddock, Javadoc or Doxygen.  By default this face inherits from
+'font-lock-constant-face'.
 
----
-*** New user option 'python-forward-sexp-function'.
-This allows the user to easier customize whether to use block-based
-navigation or not.
++++
+*** New face 'flat-button'.
+This is a plain 2D button, but uses the background color instead of
+the foreground color.
 
 ---
-*** 'python-shell-interpreter' now defaults to python3 on systems with python3.
+*** New face 'shortdoc-heading'.
+Applies to headings of shortdoc sections.
 
 ---
-*** 'C-c C-r' can now be used on arbitrary regions.
-The command previously extended the start of the region to the start
-of the line, but will now actually send the marked region, as
-documented.
-
-** Ruby mode
+*** New face 'separator-line'.
+This is used by 'make-separator-line' (see below).
 
----
-*** 'ruby-use-smie' is declared obsolete.
-SMIE is now always enabled and 'ruby-use-smie' only controls whether
-indentation is done using SMIE or with the old ad-hoc code.
+*** 'redisplay-skip-fontification-on-input' helps Emacs keep up with fast 
input.
+This is another attempt to solve the problem of handling high key repeat rate
+and other "slow scrolling" situations.  It is hoped it behaves better
+than 'fast-but-imprecise-scrolling' and 'jit-lock-defer-time'.
+It is not enabled by default.
 
-** Icomplete
+*** Obsolete aliases are no longer hidden from command completion.
+Completion of command names now considers obsolete aliases as
+candidates, if they were marked obsolete in the current major version
+of Emacs.  Invoking a command via an obsolete alias now mentions the
+obsolescence fact and shows the new name of the command.
 
----
-*** New user option 'icomplete-matches-format'.
-This allows controlling the current/total number of matches for the
-prompt prefix.
+*** Support for '(box . SIZE)' 'cursor-type'.
+By default, 'box' cursor always has a filled box shape.  But if you
+specify 'cursor-type' to be '(box . SIZE)', the cursor becomes a hollow
+box if the point is on an image larger than SIZE pixels in any
+dimension.
 
 +++
-*** New minor modes 'icomplete-vertical-mode' and 'fido-vertical-mode'
-These modes modify Icomplete ('M-x icomplete-mode') and Fido ('M-x
-fido-mode'), to display completions candidates vertically instead of
-horizontally.  In Icomplete, completions are rotated and selection
-kept at the top.  In Fido, completions scroll like a typical dropdown
-widget.  Both these new minor modes will first turn on their
-non-vertical counterparts first, if they are not on already.
+*** New user option 'lazy-highlight-no-delay-length'.
+Lazy highlighting of matches in Isearch now starts immediately if the
+search string is at least this long.  'lazy-highlight-initial-delay'
+still applies for shorter search strings, which avoids flicker in the
+search buffer due to too many matches being highlighted.
 
----
-*** Default value of 'icomplete-compute-delay' has been changed to 0.15 s.
++++
+*** The user can now customize how "default" values are prompted for.
+The new utility function 'format-prompt' has been added which uses the
+new 'minibuffer-default-prompt-format' user option to format "default"
+prompts.  This means that prompts that look like "Enter a number
+(default 10)" can be customized to look like, for instance, "Enter a
+number [10]", or not have the default displayed at all, like "Enter a
+number".  (This requires that all callers are altered to use
+'format-prompt', though.)
 
 ---
-*** Default value of 'icomplete-max-delay-chars' has been changed to 2.
+*** New help window when Emacs prompts before opening a large file.
+Commands like 'find-file' or 'visit-tags-table' ask to visit a file
+normally or literally when the file is larger than a certain size (by
+default, 9.5 MiB).  Press '?' or 'C-h' in that prompt to read more
+about the different options to visit a file, how you can disable the
+prompt, and how you can tweak the file size threshold.
 
----
-*** Reduced blinking while completing the next completions set.
-Icomplete doesn't hide the hint with the previously computed
-completions anymore when compute delay is in effect, or the previous
-computation has been aborted by input.  Instead it shows the previous
-completions until the new ones are ready.
++++
+*** Emacs now defaults to UTF-8 instead of ISO-8859-1.
+This is only for the default, where the user has set no 'LANG' (or
+similar) variable or environment.  This change should lead to no
+user-visible changes for normal usage.
 
 ---
-** Specific warnings can now be disabled from the warning buffer.
-When a warning is displayed to the user, the resulting buffer now has
-buttons which allow making permanent changes to the treatment of that
-warning.  Automatic showing of the warning can be disabled (although
-it is still logged to the "*Messages*" buffer), or the warning can be
-disabled entirely.
+*** 'global-display-fill-column-indicator-mode' skips some buffers.
+By default, turning on 'global-display-fill-column-indicator-mode'
+doesn't turn on 'display-fill-column-indicator-mode' in special-mode
+buffers.  This can be controlled by customizing the variable
+'global-display-fill-column-indicator-modes'.
 
-** mspool.el
++++
+*** 'nobreak-char-display' now also affects all non-ASCII space characters.
+Previously, this was limited only to NO-BREAK-SPACE and hyphen
+characters.  Now it also covers the rest of the non-ASCII Unicode
+space characters.
 
----
-*** Autoload the main entry point 'mspool-show'.
++++
+*** Improved support for terminal emulators that encode the Meta flag.
+Some terminal emulators set the 8th bit of Meta characters, and then
+encode the resulting character code as if it were non-ASCII character
+above codepoint 127.  Previously, the only way of using these in Emacs
+was to set up the terminal emulator to use the 'ESC' characters to send
+Meta characters to Emacs, e.g., send "ESC x" when the user types
+'M-x'.  You can now avoid the need for this setup of such terminal
+emulators by using the new input-meta-mode with the special value
+'encoded' with these terminal emulators.
 
-** Windmove
+---
+*** 'auto-composition-mode' can now be selectively disabled on some TTYs.
+Some text-mode terminals produce display glitches trying to compose
+characters.  The 'auto-composition-mode' can now have a string value
+that names a terminal type; if the value returned by the 'tty-type'
+function compares equal with that string, automatic composition will
+be disabled in windows shown on that terminal.  The Linux terminal
+sets this up by default.
 
-+++
-*** New user options to customize windmove keybindings.
-These options include 'windmove-default-keybindings',
-'windmove-display-default-keybindings',
-'windmove-delete-default-keybindings',
-'windmove-swap-states-default-keybindings'.
+---
+*** Support for the 'strike-through' face attribute on TTY frames.
+If your terminal's termcap or terminfo database entry has the 'smxx'
+capability defined, Emacs will now emit the prescribed escape
+sequences necessary to render faces with the 'strike-through'
+attribute on TTY frames.
 
-** Windows
+---
+*** TTY menu navigation is now supported in 'xterm-mouse-mode'.
+TTY menus support mouse navigation and selection when 'xterm-mouse-mode'
+is active.  When run on a terminal, clicking on the menu bar with the
+mouse now pops up a TTY menu by default instead of running the command
+'tmm-menubar'.  To restore the old behavior, set the user option
+'tty-menu-open-use-tmm' to non-nil.
 
-+++
-*** New user option 'delete-window-choose-selected'.
-This allows to choose a frame's selected window after deleting the
-previously selected one.
+---
+*** 'M-x report-emacs-bug' will no longer include "Recent messages" section.
+These were taken from the "*Messages*" buffer, and may inadvertently
+leak information from the reporting user.
 
-+++
-*** New argument NO-OTHER for some window functions.
-'get-lru-window', ‘get-mru-window’ and 'get-largest-window' now accept a
-new optional argument NO-OTHER which, if non-nil, avoids returning a
-window whose 'no-other-window' parameter is non-nil.
+---
+*** 'C-u M-x dig' will now prompt for a query type to use.
 
-+++
-*** New 'display-buffer' function 'display-buffer-use-least-recent-window'.
-This is like 'display-buffer-use-some-window', but won't reuse the
-current window, and when called repeatedly will try not to reuse a
-previously selected window.
+---
+*** Rudimentary support for the 'st' terminal emulator.
+Emacs now supports 256 color display on the 'st' terminal emulator.
 
-*** New function 'window-bump-use-time'.
-This updates the use time of a window.
+---
+*** Prefer "chat.freenode.net" to "irc.freenode.net".
+"chat.freenode.net" has been the preferred address for connecting to the
+freenode IRC network for years now.  Occurrences of "irc.freenode.net"
+have been replaced with "chat.freenode.net" throughout Emacs.
 
-*** The key prefix 'C-x 4 1' displays next command buffer in the same window.
-It's bound to the command 'same-window-prefix' that requests the buffer
-of the next command to be displayed in the same window.
+** File Locks
 
-*** The key prefix 'C-x 4 4' displays next command buffer in a new window.
-It's bound to the command 'other-window-prefix' that requests the buffer
-of the next command to be displayed in a new window.
++++
+*** New user option 'lock-file-name-transforms'.
+This option allows controlling where lock files are written.  It uses
+the same syntax as 'auto-save-file-name-transforms'.
 
-** Frames
++++
+*** New user option 'remote-file-name-inhibit-locks'.
+When non-nil, this option suppresses lock files for remote files.
 
 +++
-*** The key prefix 'C-x 5 5' displays next command buffer in a new frame.
-It's bound to the command 'other-frame-prefix' that requests the buffer
-of the next command to be displayed in a new frame.
+*** New minor mode 'lock-file-mode'.
+This command, called interactively, toggles the local value of
+'create-lockfiles' in the current buffer.
 
-** Tab Bars
+** Emacs Server
 
-*** The key prefix 'C-x t t' displays next command buffer in a new tab.
-It's bound to the command 'other-tab-prefix' that requests the buffer
-of the next command to be displayed in a new tab.
++++
+*** New user option 'server-client-instructions'.
+When emacsclient connects, Emacs will (by default) output a message
+about how to exit the client frame.  If 'server-client-instructions'
+is set to nil, this message is inhibited.
 
 +++
-*** New command 'C-x t C-r' to open file read-only in other tab.
+*** New command 'server-edit-abort'.
+This command (not bound to any key by default) can be used to abort
+an edit instead of marking it as "Done" (which the 'C-x #' command
+does).  The 'emacsclient' program exits with an abnormal status as
+result of this command.
 
----
-*** The tab bar is frame-local when 'tab-bar-show' is a number.
-Show/hide the tab bar independently for each frame, according to the
-value of 'tab-bar-show'.
++++
+*** New desktop integration for connecting to the server.
+If your operating system’s desktop environment is
+freedesktop.org-compatible (which is true of most GNU/Linux and other
+recent Unix-like GUIs), you may use the new "Emacs (Client)" desktop
+menu entry to open files in an existing Emacs instance rather than
+starting a new one.  The daemon starts if not already running.
 
----
-*** New command 'toggle-frame-tab-bar'.
-It can be used to enable/disable the tab bar individually on each frame
-independently from the value of 'tab-bar-mode' and 'tab-bar-show'.
+** Input methods
 
----
-*** New user option 'tab-bar-format' defines a list of tab bar items.
-When it contains 'tab-bar-format-global' (possibly appended after
-'tab-bar-format-align-right'), then after enabling 'display-time-mode'
-(or any other mode that uses 'global-mode-string') it displays time
-aligned to the right on the tab bar instead of the mode line.
-When 'tab-bar-format-tabs' is replaced with 'tab-bar-format-tabs-groups',
-then the tab bar displays tab groups.
++++
+*** Emacs now supports "transient" input methods.
+A transient input method is enabled for inserting a single character,
+and is then automatically disabled.  'C-x \' temporarily enables the
+selected transient input method.  Use 'C-u C-x \' to select a
+transient input method (which can be different from the input method
+enabled by 'C-\').  For example, 'C-u C-x \ compose RET' selects the
+'compose' input method; then typing 'C-x \ 1 2' will insert the
+character '½', and disable the 'compose' input method afterwards.
+You can use 'C-x \' in incremental search to insert a single character
+to the search string.
 
 ---
-*** 'Mod-9' bound to 'tab-last' now switches to the last tab.
-It also supports a negative argument.
+*** New input method 'compose' based on X Multi_key sequences.
 
 ---
-*** New command 'tab-duplicate' bound to 'C-x t n'.
+*** New input method 'iso-transl' with the same keys as 'C-x 8'.
+After selecting it as a transient input method with 'C-u C-x \
+iso-transl RET', it supports the same key sequences as 'C-x 8',
+so e.g. like 'C-x 8 [' inserts a left single quotation mark,
+'C-x \ [' does the same.
 
 ---
-*** 'C-x t N' creates a new tab at the specified absolute position.
-It also supports a negative argument.
+*** New user option 'read-char-by-name-sort'.
+It defines the sorting order of characters for completion of 'C-x 8 RET TAB'
+and can be customized to sort them by codepoints instead of character names.
+Additionally, you can group characters by Unicode blocks after customizing
+'completions-group' and 'completions-group-sort'.
 
 ---
-*** 'C-x t M' moves the current tab to the specified absolute position.
-It also supports a negative argument.
+*** Improved language transliteration in Malayalam input methods.
+Added a new Mozhi scheme.  The inapplicable ITRANS scheme is now
+deprecated.  Errors in the Inscript method were corrected.
 
 ---
-*** 'C-x t G' assigns a group name to the tab.
-'tab-close-group' can close all tabs that belong to the selected group.
-The user option 'tab-bar-new-tab-group' defines the default group of a
-new tab.  After customizing 'tab-bar-tab-post-change-group-functions'
-to 'tab-bar-move-tab-to-group', changing the tab group will also move it
-closer to other tabs in the same group.
+*** New input method 'cham'.
+There's also a Cham greeting in "etc/HELLO".
 
 ---
-*** New user option 'tab-bar-tab-name-format-function'.
+*** New input methods for Lakota language orthographies.
+Two orthographies are represented here, the Suggested Lakota
+Orthography and what is known as the White Hat Orthography.  Input
+methods 'lakota-slo-prefix', 'lakota-slo-postfix', and
+'lakota-white-hat-postfix' have been added.  There is also a Lakota
+greeting in "etc/HELLO".

+* Editing Changes in Emacs 28.1
 
----
-*** The tabs in the tab line can now be scrolled using horizontal scroll.
-If your mouse or trackpad supports it, you can now scroll tabs when
-the mouse pointer is in the tab line by scrolling left or right.
++++
+** Standalone 'M-y' allows interactive selection from previous kills.
+'M-y' can now be typed after a command that is not a yank command.
+When invoked like that, it prompts in the minibuffer for one of the
+previous kills, offering completion and minibuffer-history navigation
+through previous kills recorded in the kill ring.  A similar feature
+in Isearch can be invoked if you bind 'C-s M-y' to the command
+'isearch-yank-pop'.  When the user option 'yank-from-kill-ring-rotate'
+is nil the kill ring is not rotated after 'yank-from-kill-ring'.
 
----
-*** New tab-line faces and options.
-The face 'tab-line-tab-special' is used for tabs whose buffers are
-special, i.e. not file-backed.  The face
-'tab-line-tab-inactive-alternate' is used to display inactive tabs
-with an alternating background color, making them easier to
-distinguish between, especially if the face 'tab-line-tab' is
-configured to not display with a box; this alternate face is only
-applied when the option 'tab-line-tab-face-functions' is
-so-configured.  That option may also be used to customize tab-line
-faces in other ways.
++++
+** New command 'undo-redo'.
+It undoes previous undo commands, but doesn't record itself as an
+undoable command.
 
-** Occur mode
++++
+** New commands 'copy-matching-lines' and 'kill-matching-lines'.
+These commands are similar to the command 'flush-lines',
+but add the matching lines to the kill ring as a single string,
+including the newlines that separate the lines.
 
-*** New bindings in occur-mode, 'next-error-no-select' bound to 'n' and
-'previous-error-no-select' bound to 'p'.
++++
+** New user option 'kill-transform-function'.
+This can be used to transform (and suppress) strings from entering the
+kill ring.
 
-*** The new command 'recenter-current-error', bound to 'l' in Occur or
-compilation buffers, recenters the current displayed occurrence/error.
++++
+** 'save-interprogram-paste-before-kill' can now be a number.
+In that case, it's interpreted as a limit on the size of the clipboard
+data that will be saved to the 'kill-ring' prior to killing text: if
+the size of the clipboard data is greater than or equal to the limit,
+it will not be saved.
 
-*** Matches in target buffers are now highlighted as in 'compilation-mode'.
-The method of highlighting is specified by the user options
-'next-error-highlight' and 'next-error-highlight-no-select'.
++++
+** New user option 'tab-first-completion'.
+If 'tab-always-indent' is 'complete', this new user option can be used to
+further tweak whether to complete or indent.
 
 ---
-*** A fringe arrow in the "*Occur*" buffer indicates the selected match.
+** 'indent-tabs-mode' is now a global minor mode instead of just a variable.
 
 ---
-*** Occur mode may use a different type for 'occur-target' property values.
-The value was previously always a marker set to the start of the first
-match on the line but can now also be a list of '(BEGIN . END)' pairs
-of markers delimiting each match on the line.
-This is a fully compatible change to the internal occur-mode
-implementation, and code creating their own occur-mode buffers will
-work as before.
+** New choice 'permanent' for 'shift-select-mode'.
+When the mark was activated by shifted motion keys, non-shifted motion
+keys don't deactivate the mark after customizing 'shift-select-mode'
+to 'permanent'.
 
-** EIEIO
++++
+** The "Edit => Clear" menu item now obeys a rectangular region.
 
 +++
-*** The macro 'oref-default' can now be used with 'setf'.
-It is now defined as a generalized variable that can be used with
-'setf' to modify the value stored in a given class slot.
+** New command 'revert-buffer-with-fine-grain'.
+Revert a buffer trying to be as non-destructive as possible,
+preserving markers, properties and overlays.  The new variable
+'revert-buffer-with-fine-grain-max-seconds' specifies the maximum
+number of seconds that 'revert-buffer-with-fine-grain' should spend
+trying to be non-destructive.
+
++++
+** New command 'revert-buffer-quick'.
+This is bound to 'C-x x g' and is like `revert-buffer', but prompts
+less.
+
++++
+** New user option 'revert-buffer-quick-short-answers'.  This
+controls how the new 'revert-buffer-quick' (`C-x x g') command
+prompts.
+
++++
+** New user option 'query-about-changed-file'.
+If non-nil (the default), users are prompted as before when
+re-visiting a file that has changed externally after it was visited
+the first time.  If nil, the user is not prompted, but instead the
+buffer is opened with its contents before the change, and the user is
+given instructions how to revert the buffer.
+
+** New value 'save-some-buffers-root' of 'save-some-buffers-default-predicate'.
+It allows to ask about saving only files under the project root
+or in subdirectories of the directory that was default during
+command invocation.
 
 ---
-*** 'form' in '(eql form)' specializers in 'cl-defmethod' is now evaluated.
-This corresponds to the behavior of defmethod in Common Lisp Object System.
-For compatibility, '(eql SYMBOL)' does not evaluate SYMBOL, for now.
+** New user option 'save-place-abbreviate-file-names'.
+This can simplify sharing the ‘save-place-file’ file across
+different hosts.
 
-** New minor mode 'cl-font-lock-built-in-mode' for 'lisp-mode'.
-The mode provides refined highlighting of built-in functions, types,
-and variables.
++++
+** New user option 'word-wrap-by-category'.
+When word-wrap is enabled, and this option is non-nil, that allows
+Emacs to break lines after more characters than just whitespace
+characters.  In particular, this significantly improves word-wrapping
+for CJK text mixed with Latin text.
 
-** Archive mode
+---
+** New user options 'copy-region-blink-delay' and 'delete-pair-blink-delay'.
+'copy-region-blink-delay' specifies a delay to indicate the region
+copied by 'kill-ring-save'.  'delete-pair-blink-delay' specifies
+a delay to show a paired character to delete.
 
 ---
-*** Archive Mode can now parse ".squashfs" files.
+** 'zap-up-to-char' now uses 'read-char-from-minibuffer'.
+This allows navigating through the history of characters that have
+been input.  This is mostly useful for characters that have complex
+input methods where inputting the character again may involve many
+keystrokes.
 
-*** Can now modify members of 'ar' archives.
++++
+** Input history for 'goto-line' can now be made local to every buffer.
+In any event, line numbers used with 'goto-line' are kept in their own
+history list.  This should help make faster the process of finding
+line numbers that were previously jumped to.  By default, all buffers
+share a single history list.  To make every buffer have its own
+history list, customize the user option 'goto-line-history-local'.
 
-*** Display of summaries unified between backends.
++++
+** New command 'goto-line-relative' for use in a narrowed buffer.
+It moves point to the line relative to the accessible portion of the
+narrowed buffer.  'M-g M-g' in Info is rebound to this command.
+When 'widen-automatically' is non-nil, 'goto-line' widens the narrowed
+buffer to be able to move point to the inaccessible portion.
+'goto-line-relative' is bound to 'C-x n g'.
 
-*** New user option 'archive-hidden-columns' and command
-'archive-hideshow-column'.  These let you control which columns are
-displayed and which are kept hidden.
++++
+** When called interactively, 'goto-char' now offers the number at
+point as default.
 
----
-*** New command bound to 'C': 'archive-copy-file'.
-This command extracts the file under point and writes the data to a
-file.
+** Autosaving via 'auto-save-visited-mode' can now be inhibited by
+setting the variable 'auto-save-visited-mode' buffer-locally to nil.
 
-** Emacs Lisp mode
++++
+** New command 'C-x C-k Q' to force redisplay in keyboard macros.
 
-*** The mode-line now indicates whether we're using lexical or dynamic scoping.
+
+* Changes in Specialized Modes and Packages in Emacs 28.1
 
-*** A space between an open paren and a symbol changes the indentation rule.
-The presence of a space between an open paren and a symbol now is
-taken as a statement by the programmer that this should be indented
-as a data list rather than as a piece of code.
+** Isearch
 
-** Calendar
++++
+*** Interactive regular expression search now uses faces for sub-groups.
+E.g., 'C-M-s foo-\([0-9]+\)' will now use the 'isearch-group-1' face
+on the part of the regexp that matches the sub-expression "[0-9]+".
+By default, there are two faces for sub-group highlighting, but you
+can define more faces whose names are of the form 'isearch-group-N',
+where N are successive numbers above 2.
+
+This is controlled by the 'search-highlight-submatches' user option.
+This feature is available only on terminals that have enough colors to
+distinguish between sub-expression highlighting.
+
+*** New user option 'isearch-wrap-pause' defines how to wrap the search.
+There are choices to disable wrapping completely and to wrap immediately.
+When wrapping immediately, it consistently handles the numeric arguments
+of 'C-s' ('isearch-repeat-forward') and 'C-r' ('isearch-repeat-backward'),
+continuing with the remaining count after wrapping.
 
 +++
-*** New user option 'calendar-time-zone-style'.
-If 'numeric', calendar functions (eg 'calendar-sunrise-sunset') that display
-time zones will use a form like "+0100" instead of "CET".
+*** New user option 'isearch-repeat-on-direction-change'.
+When this option is set, direction changes in Isearch move to another
+search match, if there is one, instead of moving point to the other
+end of the current match.
+
++++
+*** Interactive regular expression replace now uses faces for sub-groups.
+Like 'search-highlight-submatches', this is controlled by the new user option
+'query-replace-highlight-submatches'.
+
+*** New key 'M-s M-.' starts isearch with the thing found at point.
+This key is bound to the new command 'isearch-forward-thing-at-point'.
+The new user option 'isearch-forward-thing-at-point' defines
+a list of symbols to try to get the "thing" at point.  By default,
+the first element of the list is 'region' that tries to yank
+the currently active region to the search string.

-+++
-*** 'vc-revert-show-diff' now has a third possible value: 'kill'.
-If this variable is 'kill', then the diff buffer will be killed after

-*** More VC commands can be used from non-file buffers.
-The relevant commands are those that don't change the VC state.
-The non-file buffers which can use VC commands are those that have
-their 'default-directory' under VC.
++++
+*** New commands to cycle heading visibility.
+Typing 'TAB' on a heading line cycles the current section between
+"hide all", "subheadings", and "show all" states.  Typing 'S-TAB'
+anywhere in the buffer cycles the whole buffer between "only top-level
+headings", "all headings and subheadings", and "show all" states.
 
-*** New command 'vc-dir-root' uses the root directory without asking.
++++
+*** New user option 'outline-minor-mode-cycle'.
+This user option customizes 'outline-minor-mode', with the difference
+that 'TAB' and 'S-TAB' on heading lines cycle heading visibility.
+Typing 'TAB' on a heading line cycles the current section between
+"hide all", "subheadings", and "show all" states.  Typing 'S-TAB' on a
+heading line cycles the whole buffer between "only top-level
+headings", "all headings and subheadings", and "show all" states.
 
 ---
-*** New face 'log-view-commit-body'.
-This is used when expanding commit messages from 'vc-print-root-log'
-and similar commands.
+*** New user option 'outline-minor-mode-highlight'.
+This user option customizes 'outline-minor-mode'.  It puts
+highlighting on heading lines using standard outline faces.  This
+works well only when there are no conflicts with faces used by the
+major mode.
 
----
-*** New faces for 'vc-dir' buffers.
-Those are: 'vc-dir-header', 'vc-dir-header-value', 'vc-dir-directory',

-*** The responsible VC backend is now the most specific one.
-'vc-responsible-backend' loops over the backends in
-'vc-handled-backends' to determine which backend is responsible for a
-specific (unregistered) file.  Previously the first matching backend
-was chosen, but now the one with the most specific path is chosen (in
-case there's a directory handled by one backend inside another).
++++
+*** 'ispell-comments-and-strings' now accepts START and END arguments,
+defaulting to active region when used interactively.
 
-*** New commands 'vc-dir-mark-registered-files' (bound to '* r') and
-'vc-dir-mark-unregistered-files'.

-It controls whether a bookmark or branch will be created when you
-invoke 'C-u C-x v s' ('vc-create-tag').
+*** '/ s' ('package-menu-filter-by-status') changes parameter handling.
+The command was documented to take a comma-separated list of statuses
+to filter by, but instead it used the parameter as a regexp.  The
+command has been changed so that it now works as documented, and
+checks statuses not as a regexp, but instead an exact match from the
+comma-separated list.

+/ /             package-menu-filter-clear
+
+*** Option to automatically native-compile packages upon installation.
+Customize the user option 'package-native-compile' to enable automatic
+native compilation of packages when they are installed.  That option
+is nil by default; if set non-nil, and if your Emacs was built with
+native-compilation support, each package will be natively compiled
+when it is installed, by invoking an asynchronous Emacs subprocess to
+run the native-compilation of the package files.
 
 ---
-*** New user option 'vc-git-revision-complete-only-branches'.
-If non-nil, only branches and remotes are considered when doing
-completion over Git branch names.  The default is nil, which causes
-tags to be considered as well.
+*** Column widths in 'list-packages' display can now be customized.
+See the new user options 'package-name-column-width',
+'package-version-column-width', 'package-status-column-width', and
+'package-archive-column-width'.

-*** New user option 'vc-git-log-switches'.
-String or list of strings specifying switches for Git log under VC.
+*** New user option 'Info-warn-on-index-alternatives-wrap'.
+This option affects what happens when using the ',' command after
+looking up an entry with 'i' in info buffers.  If non-nil (the
+default), the ',' command will now warn you when proceeding beyond the
+final entry, and tapping ',' once more will then take you to the

 +++
-*** New user option 'gnus-topic-display-predicate'.
-This can be used to inhibit the display of some topics completely.
+*** Emacs can now suggest to use an abbrev based on text you type.
+A new user option, 'abbrev-suggest', enables the new abbrev suggestion
+feature.  When enabled, if a user manually types a piece of text that
+could have saved enough typing by using an abbrev, a hint will be
+displayed in the echo area, mentioning the abbrev that could have been
+used instead.
 
-+++
-*** nnimap now supports the oauth2.el library.
+** Bookmarks
 
-+++
-*** New Summary buffer sort options for extra headers.
-The extra header sort option ('C-c C-s C-x') prompts for a header
-and fails if no sort function has been defined.  Sorting by
-Newsgroups ('C-c C-s C-u') has been pre-defined.
-
-+++
-*** The '#' command in the Group and Summary buffer now toggles,
-instead of sets, the process mark.
+*** Bookmarks can now be targets for new tabs.
+When the bookmark.el library is loaded, a customize choice is added
+to 'tab-bar-new-tab-choice' for new tabs to show the bookmark list.
 
-+++
-*** New user option 'gnus-process-mark-toggle'.
-If non-nil (the default), the '#' command in the Group and Summary
-buffers will toggle, instead of set, the process mark.
+---
+*** The 'list-bookmarks' menu is now based on 'tabulated-list-mode'.
+The interactive bookmark list will now benefit from features in
+'tabulated-list-mode' like sorting columns or changing column width.
 
+Support for the optional "inline" header line, allowing for a header
+without using 'header-line-format', has been dropped.  Consequently,
+the variables 'bookmark-bmenu-use-header-line' and
+'bookmark-bmenu-inline-header-height' are now declared obsolete.
 
-+++
-*** New user option 'gnus-registry-register-all'.
-If non-nil (the default), create registry entries for all messages.
-If nil, don't automatically create entries, they must be created
-manually.
+---
+*** New user option 'bookmark-fontify'.
+If non-nil, setting a bookmark will colorize the current line with
+'bookmark-face'.
 
-+++
-*** New user options to customise the summary line specs "%[" and "%]".
-Four new options introduced in customisation group
-'gnus-summary-format'.  These are 'gnus-sum-opening-bracket',
-'gnus-sum-closing-bracket', 'gnus-sum-opening-bracket-adopted', and
-'gnus-sum-closing-bracket-adopted'.  Their default values are "[", "]",
-"<", ">" respectively.  These options control the appearance of "%["
-and "%]" specs in the summary line format.  "%[" will normally display
-the value of 'gnus-sum-opening-bracket', but can also be
-'gnus-sum-opening-bracket-adopted' for the adopted articles.  "%]" will
-normally display the value of 'gnus-sum-closing-bracket', but can also
-be 'gnus-sum-closing-bracket-adopted' for the adopted articles.
+---
+*** New user option 'bookmark-menu-confirm-deletion'.
+In Bookmark Menu mode, Emacs by default does not prompt for
+confirmation when you type 'x' to execute the deletion of bookmarks
+that have been marked for deletion.  However, if this new option is
+non-nil then Emacs will require confirmation with 'yes-or-no-p' before
+deleting.
 
-+++
-*** New user option 'gnus-paging-select-next'.
-This controls what happens when using commands like 'SPC' and 'DEL' to
-page the current article.  If non-nil (the default), go to the
-next/prev article, but if nil, do nothing at the end/start of the article.
+** Recentf
 
-+++
-*** New gnus-search library.
-A new unified search syntax which can be used across multiple
-supported search engines.  Set 'gnus-search-use-parsed-queries' to
-non-nil to enable.
+---
+*** The recentf files are no longer backed up.
 
-+++
-*** New value for user option 'smiley-style'.
-Smileys can now be rendered with emojis instead of small images when
-using the new 'emoji' value in 'smiley-style'.
+---
+*** 'recentf-auto-cleanup' time string now repeats.
+When 'recentf-auto-cleanup' is set to a time string, it now repeats
+every day, rather than only running once after the mode is turned on.
 
-+++
-*** New user option 'gnus-agent-eagerly-store-articles'.
-If non-nil (which is the default), the Gnus Agent will store all read
-articles in the Agent cache.
+** Calc
 
-+++
-*** New user option 'gnus-global-groups'.
-Gnus handles private groups differently from public (i.e., NNTP-like)
-groups.  Most importantly, Gnus doesn't download external images from
-mail-like groups.  This can be overridden by putting group names in
-'gnus-global-groups': Any group present in that list will be treated
-like a public group.
+---
+*** The behavior when doing forward-delete has been changed.
+Previously, using the 'C-d' command would delete the final number in
+the input field, no matter where point was.  This has been changed to
+work more traditionally, with 'C-d' deleting the next character.
+Likewise, point isn't moved to the end of the string before inserting
+digits.
 
 +++
-*** New scoring types for the Date header.
-You can now score based on the relative age of an article with the new
-'<' and '>' date scoring types.
+*** Setting the word size to zero disables word clipping.
+The word size normally clips the results of certain bit-oriented
+operations such as shifts and bitwise XOR.  A word size of zero, set
+by 'b w', makes the operation have effect on the whole argument values
+and the result is not truncated in any way.
 
-+++
-*** User-defined scoring is now possible.
-The new type is 'score-fn'.  More information in the Gnus manual node
-"(gnus) Score File Format".
+---
+*** The '/' operator now has higher precedence in (La)TeX input mode.
+It no longer has lower precedence than '+' and '-'.
 
-+++
-*** New backend 'nnselect'.
-The newly added 'nnselect' backend allows creating groups from an
-arbitrary list of articles that may come from multiple groups and
-servers.  These groups generally behave like any other group: they may
-be ephemeral or persistent, and allow article marking, moving,
-deletion, etc.  'nnselect' groups may be created like any other group,
-but there are three convenience functions for the common case of
-obtaining the list of articles as a result of a search:
-'gnus-group-make-search-group' ('G g') that will prompt for an 'nnir'
-search query and create a persistent group for that search;
-'gnus-group-read-ephemeral-search-group' ('G G') that will prompt for
-an 'nnir' search query and create an ephemeral group for that search;
-and 'gnus-summary-make-group-from-search' ('C-c C-p') that will create
-a persistent group with the search parameters of a current ephemeral
-search group.
+---
+*** Calc now marks its windows dedicated.
+The new user option 'calc-make-windows-dedicated' controls this.  It
+is t by default; set to nil to get back the old behavior.
 
-As part of this addition, the user option 'nnir-summary-line-format'
-has been removed; its functionality is now available directly in the
-'gnus-summary-line-format' specs '%G' and '%g'.  The user option
-'gnus-refer-thread-use-nnir' has been renamed to
-'gnus-refer-thread-use-search'.
+** Calendar
 
 +++
-*** New user option 'gnus-dbus-close-on-sleep'.
-On systems with D-Bus support, it is now possible to register a signal
-to close all Gnus servers before the system sleeps.
+*** New user option 'calendar-time-zone-style'.
+If 'numeric', calendar functions (eg 'calendar-sunrise-sunset') that display
+time zones will use a form like "+0100" instead of "CET".
 
-+++
-*** The key binding of 'gnus-summary-search-article-forward' has changed.
-This command was previously on 'M-s' and shadowed the global 'M-s'
-search prefix.  The command has now been moved to 'M-s M-s'.  (For
-consistency, the 'M-s M-r' key binding has been added for the
-'gnus-summary-search-article-backward' command.)
+** ido
 
 ---
-*** The value of "all" in the 'large-newsgroup-initial' group parameter 
changes.
-It was previously nil, which didn't work, because nil is
-indistinguishable from not being present.  The new value for "all" is
-the symbol 'all'.
+*** Switching on 'ido-mode' now also overrides 'ffap-file-finder'.
 
-+++
-*** The name of dependent Gnus sessions has changed from "slave" to "child".
-The names of the commands 'gnus-slave', 'gnus-slave-no-server' and
-'gnus-slave-unplugged' have changed to 'gnus-child',
-'gnus-child-no-server' and 'gnus-child-unplugged' respectively.
+---
+*** Killing virtual ido buffers interactively will make them go away.
+Previously, killing a virtual ido buffer with 'ido-kill-buffer' didn't
+do anything.  This has now been changed, and killing virtual buffers
+with that command will remove the buffer from recentf.
 
-+++
-*** The 'W Q' summary mode command now takes a numerical prefix to
-allow adjusting the fill width.
+** Flyspell mode
 
 +++
-*** New variable 'mm-inline-font-lock'.
-This variable is supposed to be bound by callers to determine whether
-inline MIME parts (that support it) are supposed to be font-locked or
-not.
-
-** Message
+*** Corrections and actions menu can be optionally bound to 'mouse-3'.
+When Flyspell mode highlights a word as misspelled, you can click on
+it to display a menu of possible corrections and actions.  You can now
+easily bind this menu to 'down-mouse-3' (usually the right mouse button)
+instead of 'mouse-2' (the default) by enabling 'context-menu-mode'.
 
 ---
-*** Respect 'message-forward-ignored-headers' more.
-Previously, this user option would not be consulted if
-'message-forward-show-mml' was nil and forwarding as MIME.
-
-+++
-*** New user option 'message-forward-included-mime-headers'.
-This is used when forwarding messages as MIME, but not using MML.
+*** The current dictionary is now displayed in the minor mode lighter.
+Clicking the dictionary name changes the current dictionary.
 
-+++
-*** Message now supports the OpenPGP header.
-To generate these headers, add the new function
-'message-add-openpgp-header' to 'message-send-hook'.  The header will
-be generated according to the new 'message-openpgp-header' variable.
+** So Long
 
 ---
-*** A change to how "Mail-Copies-To: never" is handled.
-If a user has specified "Mail-Copies-To: never", and Message was asked
-to do a "wide reply", some other arbitrary recipient would end up in
-the resulting "To" header, while the remaining recipients would be put
-in the "Cc" header.  This is somewhat misleading, as it looks like
-you're responding to a specific person in particular.  This has been
-changed so that all the recipients are put in the "To" header in these
-instances.
-
-+++
-*** New command to start Emacs in Message mode to send an email.
-Emacs can be defined as a handler for the "x-scheme-handler/mailto"
-MIME type with the following command: "emacs -f message-mailto %u".
-An "emacs-mail.desktop" file has been included, suitable for
-installing in desktop directories like "/usr/share/applications" or
-"~/.local/share/applications".
-Clicking on a 'mailto:' link in other applications will then open
-Emacs with headers filled out according to the link, e.g.
-"mailto:larsi@gnus.org?subject=This+is+a+test";.  If you prefer
-emacsclient, use "emacsclient -e '(message-mailto "%u")'"
-or "emacsclient-mail.desktop".
+*** New 'so-long-predicate' function 'so-long-statistics-excessive-p'
+efficiently detects the presence of a long line anywhere in the buffer
+using 'buffer-line-statistics' (see above).  This is now the default
+predicate (replacing 'so-long-detected-long-line-p').
 
 ---
-*** Change to default value of 'message-draft-headers' user option.
-The 'Date' symbol has been removed from the default value, meaning that
-draft or delayed messages will get a date reflecting when the message
-was sent.  To restore the original behavior of dating a message
-from when it is first saved or delayed, add the symbol 'Date' back to
-this user option.
+*** 'so-long-threshold' and 'so-long-max-lines' have been raised to
+10000 bytes and 500 lines respectively, to reduce the likelihood of
+false-positives when 'global-so-long-mode' is enabled.  The latter
+value is now only used by the old predicate, as the new predicate
+knows the longest line in the entire buffer.
 
-+++
-*** New command to take screenshots.
-In Message mode buffers, the 'C-c C-p' ('message-insert-screenshot')
-command has been added.  It depends on using an external program to
-take the actual screenshot, and defaults to "ImageMagick import".
+---
+*** 'so-long-target-modes' now includes 'fundamental-mode' by default,
+meaning that 'global-so-long-mode' will also process files which were
+not recognised.  (This only has an effect if 'set-auto-mode' chooses
+'fundamental-mode'; buffers which are simply in 'fundamental-mode' by
+default are unaffected.)
 
-** Smtpmail
+---
+*** New user options 'so-long-mode-preserved-minor-modes' and
+'so-long-mode-preserved-variables' allow specified mode and variable
+states to be maintained if 'so-long-mode' replaces the original major
+mode.  By default, these new options support 'view-mode'.
 
-+++
-*** smtpmail now supports using the oauth2.el library.
+** Grep
 
 +++
-*** New user option 'smtpmail-store-queue-variables'.
-If non-nil, SMTP variables will be stored together with the queued
-messages, and will then be used when sending with
-'M-x smtpmail-send-queued-mail'.
-
-+++
-*** Allow direct selection of smtp authentication mechanism.
-A server entry retrieved by auth-source can request a desired smtp
-authentication mechanism by setting a value for the key 'smtp-auth'.
-
-** Search and Replace
-
-*** New key 'M-s M-.' starts isearch with the thing found at point.
-This key is bound to the new command 'isearch-forward-thing-at-point'.
-The new user option 'isearch-forward-thing-at-point' defines
-a list of symbols to try to get the "thing" at point.  By default,
-the first element of the list is 'region' that tries to yank
-the currently active region to the search string.
-
-*** New user option 'isearch-wrap-pause' defines how to wrap the search.
-There are choices to disable wrapping completely and to wrap immediately.
-When wrapping immediately, it consistently handles the numeric arguments
-of 'C-s' ('isearch-repeat-forward') and 'C-r' ('isearch-repeat-backward'),
-continuing with the remaining count after wrapping.
-
-** Grep
-
-+++
-*** New user option 'grep-match-regexp' matches grep markers to highlight.
-Grep emits SGR ANSI escape sequences to color its output.  The new
-user option 'grep-match-regexp' holds the regular expression to match
-the appropriate markers in order to provide highlighting in the source
-buffer.  The user option can be customized to accommodate other
-grep-like tools.

 *** The 'lgrep' command now ignores directories.
@@ -1309,596 +1349,717 @@ This change is for better compatibility with old 
versions of non-GNU
 This returns the name of the file at point (if any) in 'grep-mode'
 buffers.
 
-** Help
-
-+++
-*** New convenience commands with short keys in the Help buffer.
-New command 'help-view-source' ('s') will view the source file (if
-any) of the current help topic.  New command 'help-goto-info' ('i')
-will look up the current symbol (if any) in Info.  New command
-'help-customize' ('c') will customize the variable or the face
-(if any) whose doc string is being shown in the Help buffer.
+** Shell
 
 ---
-*** The 'help-for-help' ('C-h C-h') screen has been redesigned.
+*** New command in 'shell-mode': 'narrow-to-prompt'.
+This is bound to 'C-x n d' in 'shell-mode' buffers, and narrows to the
+command line under point (and any following output).
 
 ---
-*** Keybindings in 'help-mode' use the new 'help-key-binding' face.
-This face is added by 'substitute-command-keys' to any "\[command]"
-substitution.  The return value of that function should consequently
-be assumed to be a propertized string.
+*** New user option 'shell-has-auto-cd'.
+If non-nil, 'shell-mode' handles implicit "cd" commands, changing the
+directory if the command is a directory.  Useful for shells like "zsh"
+that has this feature.
 
-Note that the new face will also be used in tooltips.  When using the
-GTK toolkit, this is only true if 'x-gtk-use-system-tooltips' is t.
+** term-mode
 
 ---
-*** 'g' ('revert-buffer') in 'help-mode' no longer requires confirmation.
+*** New user option 'term-scroll-snap-to-bottom'.
+By default, 'term' and 'ansi-term' will now recenter the buffer so
+that the prompt is on the final line in the window.  Setting this new
+user option to nil inhibits this behavior.
 
-+++
-*** New command 'describe-command' shows help for a command.
-This can be used instead of 'describe-function' for interactive
-commands and is globally bound to 'C-h x'.
+---
+*** New user option 'term-set-terminal-size'
+If non-nil, the 'LINES' and 'COLUMNS' environment variables will be set
+based on the current window size.  In previous versions of Emacs, this
+was always done (and that could lead to odd displays when resizing the
+window after starting).  This variable defaults to nil.
 
-+++
-*** New command 'describe-keymap' describes keybindings in a keymap.
+** Eshell
 
 ---
-*** New user option 'describe-bindings-outline'.
-It enables outlines in the output buffer of 'describe-bindings' that
-can provide a better overview in a long list of available bindings.
+*** 'eshell-hist-ignoredups' can now also be used to mimic "erasedups" in bash.
 
 ---
-*** New keybinding 'C-h R' prompts for a manual to display and displays it.
+*** Environment variable 'INSIDE_EMACS' is now copied to subprocesses.
+Its value contains the result of evaluating '(format "%s,eshell"
+emacs-version)'.  Other package names, like "tramp", could also be included.
 
 ---
-*** Closing the "*Help*" buffer from the toolbar now buries the buffer.
-In previous Emacs versions, the "*Help*" buffer was killed instead when
-clicking the "X" icon in the tool bar.
+*** Eshell no longer re-initializes its keymap every call.
+This allows users to use (define-key eshell-mode-map ...) as usual.
+Some modules have their own minor mode now to account for these
+changes.
 
-** Info
+** Archive mode
 
 ---
-*** New user option 'Info-warn-on-index-alternatives-wrap'.
-This option affects what happens when using the ',' command after
-looking up an entry with 'i' in info buffers.  If non-nil (the
-default), the ',' command will now warn you when proceeding beyond the
-final entry, and tapping ',' once more will then take you to the
-first entry.
-
-+++
-** New command 'lossage-size'.
-It allows users to set the maximum number of keystrokes and commands
-recorded for the purpose of 'view-lossage'.
+*** Archive Mode can now parse ".squashfs" files.
 
----
-*** The command 'view-lossage' can now be invoked from the menu bar.
-The menu bar "Help" menu now has a "Show Recent Inputs" item under the
-"Describe" sub-menu.
+*** Can now modify members of 'ar' archives.
 
-** Input methods
+*** Display of summaries unified between backends.
 
-+++
-*** Emacs now supports "transient" input methods.
-A transient input method is enabled for inserting a single character,
-and is then automatically disabled.  'C-x \' temporarily enables the
-selected transient input method.  Use 'C-u C-x \' to select a
-transient input method (which can be different from the input method
-enabled by 'C-\').  For example, 'C-u C-x \ compose RET' selects the
-'compose' input method; then typing 'C-x \ 1 2' will insert the
-character '½', and disable the 'compose' input method afterwards.
-You can use 'C-x \' in incremental search to insert a single character
-to the search string.
+*** New user option 'archive-hidden-columns' and command
+'archive-hideshow-column'.  These let you control which columns are
+displayed and which are kept hidden.
 
 ---
-*** New input method 'compose' based on X Multi_key sequences.
+*** New command bound to 'C': 'archive-copy-file'.
+This command extracts the file under point and writes the data to a
+file.
 
----
-*** New input method 'iso-transl' with the same keys as 'C-x 8'.
-After selecting it as a transient input method with 'C-u C-x \
-iso-transl RET', it supports the same key sequences as 'C-x 8',
-so e.g. like 'C-x 8 [' inserts a left single quotation mark,
-'C-x \ [' does the same.
+** browse-url
 
----
-*** New user option 'read-char-by-name-sort'.
-It defines the sorting order of characters for completion of 'C-x 8 RET TAB'
-and can be customized to sort them by codepoints instead of character names.
-Additionally, you can group characters by Unicode blocks after customizing
-'completions-group' and 'completions-group-sort'.
+*** Added support for custom URL handlers.
+There is a new variable 'browse-url-default-handlers' and a user
+option 'browse-url-handlers' being alists with '(REGEXP-OR-PREDICATE
+. FUNCTION)' entries allowing to define different browsing FUNCTIONs
+depending on the URL to be browsed.  The variable is for default
+handlers provided by Emacs itself or external packages, the user
+option is for the user (and allows for overriding the default
+handlers).
 
----
-*** Improved language transliteration in Malayalam input methods.
-Added a new Mozhi scheme.  The inapplicable ITRANS scheme is now
-deprecated.  Errors in the Inscript method were corrected.
+Formerly, one could do the same by setting
+'browse-url-browser-function' to such an alist.  This usage is still
+supported but deprecated.
 
----
-*** New input method 'cham'.
-There's also a Cham greeting in "etc/HELLO".
+*** Categorization of browsing commands in internal vs. external.
+All standard browsing commands such as 'browse-url-firefox',
+'browse-url-mail', or 'eww' have been categorized into internal (URL
+is browsed in Emacs) or external (an external application is spawned
+with the URL).  This is done by adding a 'browse-url-browser-kind'
+symbol property to the browsing commands.  With a new command
+'browse-url-with-browser-kind', an URL can explicitly be browsed with
+either an internal or external browser.
 
 ---
-*** New input methods for Lakota language orthographies.
-Two orthographies are represented here, the Suggested Lakota
-Orthography and what is known as the White Hat Orthography.  Input
-methods 'lakota-slo-prefix', 'lakota-slo-postfix', and
-'lakota-white-hat-postfix' have been added.  There is also a Lakota
-greeting in "etc/HELLO".
+*** Support for browsing of remote files.
+If a remote file is taken, a local temporary copy of that file is
+passed to the browser.
 
-** Ispell
+*** Support for the conkeror browser is now obsolete.
 
-+++
-*** 'ispell-comments-and-strings' now accepts START and END arguments,
-defaulting to active region when used interactively.
+*** Support for the Mosaic browser has been removed.
+This support has been obsolete since 25.1.
+
+** Completion List Mode
+New key bindings have been added to 'completion-list-mode': 'n' and
+'p' now navigate completions, and 'M-g M-c' switches to the
+minibuffer and back to the completion list buffer.
 
 +++
-*** New command 'ispell-comment-or-string-at-point' is provided.
+** profiler.el
+The results displayed by 'profiler-report' now have the usage figures
+at the left hand side followed by the function name.  This is intended
+to make better use of the horizontal space, in particular eliminating
+the truncation of function names.  There is no way to get the former
+layout back.
 
----
-** The old non-SMIE indentation of 'sh-mode' has been removed.
+** Python mode
 
 ---
-** The sb-image.el library is now marked obsolete.
-This file was a compatibility kludge which is no longer needed.
+*** New user option 'python-forward-sexp-function'.
+This allows the user to easier customize whether to use block-based
+navigation or not.
 
 ---
-** Lisp mode now uses 'common-lisp-indent-function'.
-To revert to the previous behavior,
-'(setq lisp-indent-function 'lisp-indent-function)' from 'lisp-mode-hook'.
-
-** Customize
+*** 'python-shell-interpreter' now defaults to python3 on systems with python3.
 
 ---
-*** Customize buffers can now be reverted with 'C-x x g'.
+*** 'C-c C-r' can now be used on arbitrary regions.
+The command previously extended the start of the region to the start
+of the line, but will now actually send the marked region, as
+documented.
 
-*** Most customize commands now hide obsolete user options.
-Obsolete user options are no longer shown in the listings produced by
-the commands 'customize', 'customize-group', 'customize-apropos' and
-'customize-changed'.
+** Perl mode
 
-To customize obsolete user options, use 'customize-option' or
-'customize-saved'.
+---
+*** New face 'perl-non-scalar-variable'.
+This is used to fontify non-scalar variables.
 
-*** New SVG icons for checkboxes and arrows.
-They will be used automatically instead of the old icons.  If Emacs is
-built without SVG support, the old icons will be used instead.
+** Icomplete
 
-** Bookmarks
+---
+*** New user option 'icomplete-matches-format'.
+This allows controlling the current/total number of matches for the
+prompt prefix.
 
-*** Bookmarks can now be targets for new tabs.
-When the bookmark.el library is loaded, a customize choice is added
-to 'tab-bar-new-tab-choice' for new tabs to show the bookmark list.
++++
+*** New minor modes 'icomplete-vertical-mode' and 'fido-vertical-mode'
+These modes modify Icomplete ('M-x icomplete-mode') and Fido ('M-x
+fido-mode'), to display completions candidates vertically instead of
+horizontally.  In Icomplete, completions are rotated and selection
+kept at the top.  In Fido, completions scroll like a typical dropdown
+widget.  Both these new minor modes will first turn on their
+non-vertical counterparts first, if they are not on already.
 
 ---
-*** The 'list-bookmarks' menu is now based on 'tabulated-list-mode'.
-The interactive bookmark list will now benefit from features in
-'tabulated-list-mode' like sorting columns or changing column width.
+*** Default value of 'icomplete-compute-delay' has been changed to 0.15 s.
 
-Support for the optional "inline" header line, allowing for a header
-without using 'header-line-format', has been dropped.  Consequently,
-the variables 'bookmark-bmenu-use-header-line' and
-'bookmark-bmenu-inline-header-height' are now declared obsolete.
+---
+*** Default value of 'icomplete-max-delay-chars' has been changed to 2.
 
 ---
-*** New user option 'bookmark-fontify'.
-If non-nil, setting a bookmark will colorize the current line with
-'bookmark-face'.
+*** Reduced blinking while completing the next completions set.
+Icomplete doesn't hide the hint with the previously computed
+completions anymore when compute delay is in effect, or the previous
+computation has been aborted by input.  Instead it shows the previous
+completions until the new ones are ready.
 
 ---
-*** New user option 'bookmark-menu-confirm-deletion'.
-In Bookmark Menu mode, Emacs by default does not prompt for
-confirmation when you type 'x' to execute the deletion of bookmarks
-that have been marked for deletion.  However, if this new option is
-non-nil then Emacs will require confirmation with 'yes-or-no-p' before
-deleting.
+*** Change in meaning of 'icomplete-show-matches-on-no-input'.
+Previously, choosing a different completion with commands like 'C-.'
+and then hitting 'RET' would choose the default completion.  Doing this
+will now choose the completion under point instead.  Also when this option
+is nil, completions are not shown when the minibuffer reads a file name
+with initial input as the default directory.
 
-** Edebug
+** mspool.el
 
-*** Obsoletions
 ---
-**** 'get-edebug-spec' is obsolete, replaced by 'edebug-get-spec'.
-+++
-**** The spec operator ':name NAME' is obsolete, use '&name' instead.
-+++
-**** The spec element 'function-form' is obsolete, use 'form' instead.
+*** Autoload the main entry point 'mspool-show'.
 
----
-*** rfc2368.el is now obsolete.
-Use rfc6068.el instead.  The main difference is that
-'rfc2368-parse-mailto-url' and 'rfc2368-unhexify-string' assumed that
-the strings were all-ASCII, while 'rfc6068-parse-mailto-url' and
-'rfc6068-unhexify-string' parse UTF-8 strings.
+** Windmove
 
 +++
-*** New function 'def-edebug-elem-spec' to define Edebug spec elements.
-These used to be defined with 'def-edebug-spec' thus conflating the
-two name spaces, which lead to name collisions.
-The use of 'def-edebug-spec' to define Edebug spec elements is
-declared obsolete.
+*** New user options to customize windmove keybindings.
+These options include 'windmove-default-keybindings',
+'windmove-display-default-keybindings',
+'windmove-delete-default-keybindings',
+'windmove-swap-states-default-keybindings'.
 
-*** Edebug specification lists can use some new keywords:
+** Occur mode
 
-+++
-**** '&interpose SPEC FUN ARGS..' lets FUN control parsing after SPEC.
-More specifically, FUN is called with 'HEAD PF ARGS..' where
-PF is a parsing function that expects a single argument (the specs to
-use) and HEAD is the code that matched SPEC.
+*** New bindings in occur-mode, 'next-error-no-select' bound to 'n' and
+'previous-error-no-select' bound to 'p'.
 
-+++
-**** '&error MSG' unconditionally aborts the current edebug instrumentation.
+*** The new command 'recenter-current-error', bound to 'l' in Occur or
+compilation buffers, recenters the current displayed occurrence/error.
 
-+++
-**** '&name SPEC FUN' extracts the current name from the code matching SPEC.
+*** Matches in target buffers are now highlighted as in 'compilation-mode'.
+The method of highlighting is specified by the user options
+'next-error-highlight' and 'next-error-highlight-no-select'.
 
-** ElDoc
+---
+*** A fringe arrow in the "*Occur*" buffer indicates the selected match.
 
-+++
-*** New user option 'eldoc-echo-area-display-truncation-message'.
-If non-nil (the default), eldoc will display a message saying
-something like "(Documentation truncated.  Use `M-x eldoc-doc-buffer'
-to see rest)" when a message has been truncated.  If nil, truncated
-messages will be marked with just "..." at the end.
+---
+*** Occur mode may use a different type for 'occur-target' property values.
+The value was previously always a marker set to the start of the first
+match on the line but can now also be a list of '(BEGIN . END)' pairs
+of markers delimiting each match on the line.
+This is a fully compatible change to the internal occur-mode
+implementation, and code creating their own occur-mode buffers will
+work as before.
 
-+++
-*** New hook 'eldoc-documentation-functions'.
-This hook is intended to be used for registering doc string functions.
-These functions don't need to produce the doc string right away, they
-may arrange for it to be produced asynchronously.  The results of all
-doc string functions are accessible to the user through the user
-option 'eldoc-documentation-strategy'.
+** New minor mode 'cl-font-lock-built-in-mode' for 'lisp-mode'.
+The mode provides refined highlighting of built-in functions, types,
+and variables.
 
-*** New hook 'eldoc-display-functions'.
-This hook is intended to be used for displaying doc strings.  The
-functions receive the doc string composed according to
-'eldoc-documentation-strategy' and are tasked with displaying it to
-the user.  Examples of such functions would use the echo area, a
-separate buffer, or a tooltip.
+** Emacs Lisp mode
+
+*** The mode-line now indicates whether we're using lexical or dynamic scoping.
+
+*** A space between an open paren and a symbol changes the indentation rule.
+The presence of a space between an open paren and a symbol now is
+taken as a statement by the programmer that this should be indented
+as a data list rather than as a piece of code.
+
+** Change Logs and VC
 
 +++
-*** New user option 'eldoc-documentation-strategy'.
-The built-in choices available for this user option let users compose
-the results of 'eldoc-documentation-functions' in various ways, even
-if some of those functions are synchronous and some asynchronous.
-The user option replaces 'eldoc-documentation-function', which is now
-obsolete.
+*** 'vc-revert-show-diff' now has a third possible value: 'kill'.
+If this variable is 'kill', then the diff buffer will be killed after
+the 'vc-revert' action instead of buried.
 
-*** 'eldoc-echo-area-use-multiline-p' is now handled by ElDoc.
-The user option 'eldoc-echo-area-use-multiline-p' is now handled
-by the ElDoc library itself.  Functions in
-'eldoc-documentation-functions' don't need to worry about consulting
-it when producing a doc string.
+*** More VC commands can be used from non-file buffers.
+The relevant commands are those that don't change the VC state.
+The non-file buffers which can use VC commands are those that have
+their 'default-directory' under VC.
 
-** Shell
+*** New command 'vc-dir-root' uses the root directory without asking.
 
 ---
-*** New command in 'shell-mode': 'narrow-to-prompt'.
-This is bound to 'C-x n d' in 'shell-mode' buffers, and narrows to the
-command line under point (and any following output).
+*** New face 'log-view-commit-body'.
+This is used when expanding commit messages from 'vc-print-root-log'
+and similar commands.
 
 ---
-*** New user option 'shell-has-auto-cd'.
-If non-nil, 'shell-mode' handles implicit "cd" commands, changing the
-directory if the command is a directory.  Useful for shells like "zsh"
-that has this feature.
-
-** Eshell
+*** New faces for 'vc-dir' buffers.
+Those are: 'vc-dir-header', 'vc-dir-header-value', 'vc-dir-directory',
+'vc-dir-file', 'vc-dir-mark-indicator', 'vc-dir-status-warning',
+'vc-dir-status-edited', 'vc-dir-status-up-to-date',
+'vc-dir-status-ignored'.
 
 ---
-*** 'eshell-hist-ignoredups' can now also be used to mimic "erasedups" in bash.
+*** The responsible VC backend is now the most specific one.
+'vc-responsible-backend' loops over the backends in
+'vc-handled-backends' to determine which backend is responsible for a
+specific (unregistered) file.  Previously the first matching backend
+was chosen, but now the one with the most specific path is chosen (in
+case there's a directory handled by one backend inside another).
+
+*** New commands 'vc-dir-mark-registered-files' (bound to '* r') and
+'vc-dir-mark-unregistered-files'.
+
+*** Support for bookmark.el.
+Bookmark locations can refer to VC directory buffers.
 
 ---
-*** Environment variable 'INSIDE_EMACS' is now copied to subprocesses.
-Its value contains the result of evaluating '(format "%s,eshell"
-emacs-version)'.  Other package names, like "tramp", could also be included.
+*** New user option 'vc-hg-create-bookmark'.
+It controls whether a bookmark or branch will be created when you
+invoke 'C-u C-x v s' ('vc-create-tag').
 
 ---
-*** Eshell no longer re-initializes its keymap every call.
-This allows users to use (define-key eshell-mode-map ...) as usual.
-Some modules have their own minor mode now to account for these
-changes.
+*** 'vc-hg' now uses 'hg summary' to populate extra 'vc-dir' headers.
 
-** EUDC
+---
+*** New user option 'vc-git-revision-complete-only-branches'.
+If non-nil, only branches and remotes are considered when doing
+completion over Git branch names.  The default is nil, which causes
+tags to be considered as well.
 
-+++
-*** New macOS Contacts backend.
-This backend works on newer versions of macOS and is generally
-preferred over the eudcb-mab.el backend.
+---
+*** New user option 'vc-git-log-switches'.
+String or list of strings specifying switches for Git log under VC.
 
-** Tramp
+** Gnus
 
 +++
-*** New connection method "mtp", which allows accessing media devices
-like cell phones, tablets or cameras.
+*** New user option 'gnus-topic-display-predicate'.
+This can be used to inhibit the display of some topics completely.
 
 +++
-*** New connection method "sshfs", which allows accessing remote files
-via a file system mounted with 'sshfs'.
+*** nnimap now supports the oauth2.el library.
 
 +++
-*** Tramp supports SSH authentication via a hardware security key now.
-This requires at least OpenSSH 8.2, and a FIDO U2F compatible
-security key, like yubikey, solokey, or nitrokey.
+*** New Summary buffer sort options for extra headers.
+The extra header sort option ('C-c C-s C-x') prompts for a header
+and fails if no sort function has been defined.  Sorting by
+Newsgroups ('C-c C-s C-u') has been pre-defined.
 
 +++
-*** Trashed remote files are moved to the local trash directory.
-All remote files, which are trashed, are moved to the local trash
-directory.  Except remote encrypted files, which are always deleted.
+*** The '#' command in the Group and Summary buffer now toggles,
+instead of sets, the process mark.
 
 +++
-*** New command 'tramp-crypt-add-directory'.
-This command marks a remote directory to contain only encrypted files.
-See the "(tramp) Keeping files encrypted" node of the Tramp manual for
-details.  This feature is experimental.
+*** New user option 'gnus-process-mark-toggle'.
+If non-nil (the default), the '#' command in the Group and Summary
+buffers will toggle, instead of set, the process mark.
+
 
 +++
-*** Support of direct asynchronous process invocation.
-When Tramp connection property "direct-async-process" is set to
-non-nil for a given connection, 'make-process' and 'start-file-process'
-calls are performed directly as in "ssh ... <command>".  This avoids
-initialization performance penalties.  See the "(tramp) Improving
-performance of asynchronous remote processes" node of the Tramp manual
-for details, and also for a discussion or restrictions.  This feature
-is experimental.
+*** New user option 'gnus-registry-register-all'.
+If non-nil (the default), create registry entries for all messages.
+If nil, don't automatically create entries, they must be created
+manually.
 
 +++
-*** New user option 'tramp-debug-to-file'.
-When non-nil, this user option instructs Tramp to mirror the debug
-buffer to a file under the "/tmp/" directory.  This is useful, if (in
-rare cases) Tramp blocks Emacs, and we need further debug information.
+*** New user options to customise the summary line specs "%[" and "%]".
+Four new options introduced in customisation group
+'gnus-summary-format'.  These are 'gnus-sum-opening-bracket',
+'gnus-sum-closing-bracket', 'gnus-sum-opening-bracket-adopted', and
+'gnus-sum-closing-bracket-adopted'.  Their default values are "[", "]",
+"<", ">" respectively.  These options control the appearance of "%["
+and "%]" specs in the summary line format.  "%[" will normally display
+the value of 'gnus-sum-opening-bracket', but can also be
+'gnus-sum-opening-bracket-adopted' for the adopted articles.  "%]" will
+normally display the value of 'gnus-sum-closing-bracket', but can also
+be 'gnus-sum-closing-bracket-adopted' for the adopted articles.
 
 +++
-*** Tramp supports lock files now.
-In order to deactivate this, set user option
-'remote-file-name-inhibit-locks' to t.
+*** New user option 'gnus-paging-select-next'.
+This controls what happens when using commands like 'SPC' and 'DEL' to
+page the current article.  If non-nil (the default), go to the
+next/prev article, but if nil, do nothing at the end/start of the article.
 
 +++
-*** Writing sensitive auto-save, backup or lock files to the local
-temporary directory must be confirmed.  In order to suppress this
-confirmation, set user option 'tramp-allow-unsafe-temporary-files' to
-t.
+*** New gnus-search library.
+A new unified search syntax which can be used across multiple
+supported search engines.  Set 'gnus-search-use-parsed-queries' to
+non-nil to enable.
 
-** Tempo
++++
+*** New value for user option 'smiley-style'.
+Smileys can now be rendered with emojis instead of small images when
+using the new 'emoji' value in 'smiley-style'.
 
----
-*** 'tempo-define-template' can now re-assign templates to tags.
-Previously, assigning a new template to an already defined tag had no
-effect.
++++
+*** New user option 'gnus-agent-eagerly-store-articles'.
+If non-nil (which is the default), the Gnus Agent will store all read
+articles in the Agent cache.
 
-** map.el
++++
+*** New user option 'gnus-global-groups'.
+Gnus handles private groups differently from public (i.e., NNTP-like)
+groups.  Most importantly, Gnus doesn't download external images from
+mail-like groups.  This can be overridden by putting group names in
+'gnus-global-groups': Any group present in that list will be treated
+like a public group.
 
-*** Pcase 'map' pattern added keyword symbols abbreviation.
-A pattern like '(map :sym)' binds the map's value for ':sym' to 'sym',
-equivalent to '(map (:sym sym))'.
-
----
-*** The function 'map-copy' now uses 'copy-alist' on alists.
-This is a slightly deeper copy than the previous 'copy-sequence'.
-
----
-*** The function 'map-contains-key' now supports plists.
++++
+*** New scoring types for the Date header.
+You can now score based on the relative age of an article with the new
+'<' and '>' date scoring types.
 
----
-*** More consistent duplicate key handling in 'map-merge-with'.
-Until now, 'map-merge-with' promised to call its function argument
-whenever multiple maps contained 'eql' keys.  However, this did not
-always coincide with the keys that were actually merged, which could
-be 'equal' instead.  The function argument is now called whenever keys
-are merged, for greater consistency with 'map-merge' and 'map-elt'.
++++
+*** User-defined scoring is now possible.
+The new type is 'score-fn'.  More information in the Gnus manual node
+"(gnus) Score File Format".
 
-** Package
++++
+*** New backend 'nnselect'.
+The newly added 'nnselect' backend allows creating groups from an
+arbitrary list of articles that may come from multiple groups and
+servers.  These groups generally behave like any other group: they may
+be ephemeral or persistent, and allow article marking, moving,
+deletion, etc.  'nnselect' groups may be created like any other group,
+but there are three convenience functions for the common case of
+obtaining the list of articles as a result of a search:
+'gnus-group-make-search-group' ('G g') that will prompt for an 'nnir'
+search query and create a persistent group for that search;
+'gnus-group-read-ephemeral-search-group' ('G G') that will prompt for
+an 'nnir' search query and create an ephemeral group for that search;
+and 'gnus-summary-make-group-from-search' ('C-c C-p') that will create
+a persistent group with the search parameters of a current ephemeral
+search group.
 
----
-*** '/ s' ('package-menu-filter-by-status') changes parameter handling.
-The command was documented to take a comma-separated list of statuses
-to filter by, but instead it used the parameter as a regexp.  The
-command has been changed so that it now works as documented, and
-checks statuses not as a regexp, but instead an exact match from the
-comma-separated list.
+As part of this addition, the user option 'nnir-summary-line-format'
+has been removed; its functionality is now available directly in the
+'gnus-summary-line-format' specs '%G' and '%g'.  The user option
+'gnus-refer-thread-use-nnir' has been renamed to
+'gnus-refer-thread-use-search'.
 
 +++
-*** New command 'package-browse-url' and keystroke 'w'.
+*** New user option 'gnus-dbus-close-on-sleep'.
+On systems with D-Bus support, it is now possible to register a signal
+to close all Gnus servers before the system sleeps.
 
 +++
-*** New commands to filter the package list.
-The filter commands are bound to the following keys:
-
-key             binding
----             -------
-/ a             package-menu-filter-by-archive
-/ d             package-menu-filter-by-description
-/ k             package-menu-filter-by-keyword
-/ N             package-menu-filter-by-name-or-description
-/ n             package-menu-filter-by-name
-/ s             package-menu-filter-by-status
-/ v             package-menu-filter-by-version
-/ m             package-menu-filter-marked
-/ u             package-menu-filter-upgradable
-/ /             package-menu-filter-clear
-
-*** Option to automatically native-compile packages upon installation.
-Customize the user option 'package-native-compile' to enable automatic
-native compilation of packages when they are installed.  That option
-is nil by default; if set non-nil, and if your Emacs was built with
-native-compilation support, each package will be natively compiled
-when it is installed, by invoking an asynchronous Emacs subprocess to
-run the native-compilation of the package files.
+*** The key binding of 'gnus-summary-search-article-forward' has changed.
+This command was previously on 'M-s' and shadowed the global 'M-s'
+search prefix.  The command has now been moved to 'M-s M-s'.  (For
+consistency, the 'M-s M-r' key binding has been added for the
+'gnus-summary-search-article-backward' command.)
 
 ---
-*** Column widths in 'list-packages' display can now be customized.
-See the new user options 'package-name-column-width',
-'package-version-column-width', 'package-status-column-width', and
-'package-archive-column-width'.
-
-** gdb-mi
-
-*** New user option 'gdb-registers-enable-filter'.
-If non-nil, apply a register filter based on
-'gdb-registers-filter-pattern-list'.
-
-+++
-*** gdb-mi can now store and restore window configurations.
-Use 'gdb-save-window-configuration' to save window configuration to a
-file and 'gdb-load-window-configuration' to load from a file.  These
-commands can also be accessed through the menu bar under "Gud =>
-GDB-Windows".  'gdb-default-window-configuration-file', when non-nil,
-is loaded when GDB starts up.
+*** The value of "all" in the 'large-newsgroup-initial' group parameter 
changes.
+It was previously nil, which didn't work, because nil is
+indistinguishable from not being present.  The new value for "all" is
+the symbol 'all'.
 
 +++
-*** gdb-mi can now restore window configuration after quit.
-Set 'gdb-restore-window-configuration-after-quit' to non-nil and Emacs
-will remember the window configuration before GDB started and restore
-it after GDB quits.  A toggle button is also provided under "Gud =>
-GDB-Windows".
+*** The name of dependent Gnus sessions has changed from "slave" to "child".
+The names of the commands 'gnus-slave', 'gnus-slave-no-server' and
+'gnus-slave-unplugged' have changed to 'gnus-child',
+'gnus-child-no-server' and 'gnus-child-unplugged' respectively.
 
 +++
-*** gdb-mi now has a better logic for displaying source buffers.
-Now GDB only uses one source window to display source file by default.
-Customize 'gdb-max-source-window-count' to use more than one window.
-Control source file display by 'gdb-display-source-buffer-action'.
+*** The 'W Q' summary mode command now takes a numerical prefix to
+allow adjusting the fill width.
 
 +++
-*** The default value of 'gdb-mi-decode-strings' is now t.
-This means that the default coding-system is now used to decode strings
-and source file names from GDB.
-
-** Gravatar
-
----
-*** New user option 'gravatar-service' for host to query for gravatars.
-Defaults to 'libravatar', with 'unicornify' and 'gravatar' as options.
+*** New variable 'mm-inline-font-lock'.
+This variable is supposed to be bound by callers to determine whether
+inline MIME parts (that support it) are supposed to be font-locked or
+not.
 
-** Compilation mode
+** Message
 
 ---
-*** New function 'ansi-color-compilation-filter'.
-This function is meant to be used in 'compilation-filter-hook'.
+*** Respect 'message-forward-ignored-headers' more.
+Previously, this user option would not be consulted if
+'message-forward-show-mml' was nil and forwarding as MIME.
 
----
-*** New user option 'ansi-color-for-compilation-mode'.
-This controls what 'ansi-color-compilation-filter' does.
++++
+*** New user option 'message-forward-included-mime-headers'.
+This is used when forwarding messages as MIME, but not using MML.
 
-*** Regexp matching of messages is now case-sensitive by default.
-The variable 'compilation-error-case-fold-search' can be set for
-case-insensitive matching of messages when the old behavior is
-required, but the recommended solution is to use a correctly matching
-regexp instead.
++++
+*** Message now supports the OpenPGP header.
+To generate these headers, add the new function
+'message-add-openpgp-header' to 'message-send-hook'.  The header will
+be generated according to the new 'message-openpgp-header' variable.
 
 ---
-*** New user option 'compilation-search-all-directories'.
-When doing parallel builds, directories and compilation errors may
-arrive in the "*compilation*" buffer out-of-order.  If this variable is
-non-nil (the default), Emacs will now search backwards in the buffer
-for any directory the file with errors may be in.  If nil, this won't
-be done (and this restores how this previously worked).
+*** A change to how "Mail-Copies-To: never" is handled.
+If a user has specified "Mail-Copies-To: never", and Message was asked
+to do a "wide reply", some other arbitrary recipient would end up in
+the resulting "To" header, while the remaining recipients would be put
+in the "Cc" header.  This is somewhat misleading, as it looks like
+you're responding to a specific person in particular.  This has been
+changed so that all the recipients are put in the "To" header in these
+instances.
 
----
-*** Messages from ShellCheck are now recognized.
++++
+*** New command to start Emacs in Message mode to send an email.
+Emacs can be defined as a handler for the "x-scheme-handler/mailto"
+MIME type with the following command: "emacs -f message-mailto %u".
+An "emacs-mail.desktop" file has been included, suitable for
+installing in desktop directories like "/usr/share/applications" or
+"~/.local/share/applications".
+Clicking on a 'mailto:' link in other applications will then open
+Emacs with headers filled out according to the link, e.g.
+"mailto:larsi@gnus.org?subject=This+is+a+test";.  If you prefer
+emacsclient, use "emacsclient -e '(message-mailto "%u")'"
+or "emacsclient-mail.desktop".
 
 ---
-*** Messages from Visual Studio that mention column numbers are now recognized.
+*** Change to default value of 'message-draft-headers' user option.
+The 'Date' symbol has been removed from the default value, meaning that
+draft or delayed messages will get a date reflecting when the message
+was sent.  To restore the original behavior of dating a message
+from when it is first saved or delayed, add the symbol 'Date' back to
+this user option.
 
-** Hi Lock mode
++++
+*** New command to take screenshots.
+In Message mode buffers, the 'C-c C-p' ('message-insert-screenshot')
+command has been added.  It depends on using an external program to
+take the actual screenshot, and defaults to "ImageMagick import".
 
----
-*** Matching in 'hi-lock-mode' is case-sensitive when regexp contains
-upper case characters and 'search-upper-case' is non-nil.
-'highlight-phrase' also uses 'search-whitespace-regexp'
-to substitute spaces in regexp search.
+** Smtpmail
 
----
-*** The default value of 'hi-lock-highlight-range' was enlarged.
-The new default value is 2000000 (2 megabytes).
++++
+*** smtpmail now supports using the oauth2.el library.
 
-** Whitespace mode
++++
+*** New user option 'smtpmail-store-queue-variables'.
+If non-nil, SMTP variables will be stored together with the queued
+messages, and will then be used when sending with
+'M-x smtpmail-send-queued-mail'.
 
 +++
-*** New style 'missing-newline-at-eof'.
-If present in 'whitespace-style' (as it is by default), the final
-character in the buffer will be highlighted if the buffer doesn't end
-with a newline.
+*** Allow direct selection of smtp authentication mechanism.
+A server entry retrieved by auth-source can request a desired smtp
+authentication mechanism by setting a value for the key 'smtp-auth'.
 
 ---
-*** The default 'whitespace-enable-predicate' predicate has changed.
-It used to check elements in the list version of
-'whitespace-global-modes' with 'eq', but now uses 'derived-mode-p'.
+** Lisp mode now uses 'common-lisp-indent-function'.
+To revert to the previous behavior,
+'(setq lisp-indent-function 'lisp-indent-function)' from 'lisp-mode-hook'.
 
-** Texinfo
+** ElDoc
 
----
-*** New user option 'texinfo-texi2dvi-options'.
-This is used when invoking 'texi2dvi' from 'texinfo-tex-buffer'.
++++
+*** New user option 'eldoc-echo-area-display-truncation-message'.
+If non-nil (the default), eldoc will display a message saying
+something like "(Documentation truncated.  Use `M-x eldoc-doc-buffer'
+to see rest)" when a message has been truncated.  If nil, truncated
+messages will be marked with just "..." at the end.
 
----
-*** New commands for moving in and between environments.
-An "environment" is something that ends with '@end'.  The commands are
-'C-c C-c C-f' (next end), 'C-c C-c C-b' (previous end),
-'C-c C-c C-n' (next start) and 'C-c C-c C-p' (previous start), as well
-as 'C-c .', which will alternate between the start and the end of the
-current environment.
++++
+*** New hook 'eldoc-documentation-functions'.
+This hook is intended to be used for registering doc string functions.
+These functions don't need to produce the doc string right away, they
+may arrange for it to be produced asynchronously.  The results of all
+doc string functions are accessible to the user through the user
+option 'eldoc-documentation-strategy'.
 
-** Rmail
+*** New hook 'eldoc-display-functions'.
+This hook is intended to be used for displaying doc strings.  The
+functions receive the doc string composed according to
+'eldoc-documentation-strategy' and are tasked with displaying it to
+the user.  Examples of such functions would use the echo area, a
+separate buffer, or a tooltip.
 
----
-*** New user option 'rmail-re-abbrevs'.
-Its default value matches localized abbreviations of the "reply"
-prefix on the Subject line in various languages.
++++
+*** New user option 'eldoc-documentation-strategy'.
+The built-in choices available for this user option let users compose
+the results of 'eldoc-documentation-functions' in various ways, even
+if some of those functions are synchronous and some asynchronous.
+The user option replaces 'eldoc-documentation-function', which is now
+obsolete.
 
----
-*** New user option 'shr-offer-extend-specpdl'.
-If this is nil, rendering of HTML in the email message body that
-requires to enlarge 'max-specpdl-size', the number of Lisp variable
-bindings, will be aborted, and Emacs will not ask you whether to
-enlarge 'max-specpdl-size' to complete the rendering.  The default is
-t, which preserves the original behavior.
+*** 'eldoc-echo-area-use-multiline-p' is now handled by ElDoc.
+The user option 'eldoc-echo-area-use-multiline-p' is now handled
+by the ElDoc library itself.  Functions in
+'eldoc-documentation-functions' don't need to worry about consulting
+it when producing a doc string.
 
----
-*** New user option 'rmail-show-message-set-modified'.
-If set non-nil, showing an unseen message will set the Rmail buffer's
-modified flag.
+** Tramp
+
++++
+*** New connection method "mtp", which allows accessing media devices
+like cell phones, tablets or cameras.
+
++++
+*** New connection method "sshfs", which allows accessing remote files
+via a file system mounted with 'sshfs'.
+
++++
+*** Tramp supports SSH authentication via a hardware security key now.
+This requires at least OpenSSH 8.2, and a FIDO U2F compatible
+security key, like yubikey, solokey, or nitrokey.
+
++++
+*** Trashed remote files are moved to the local trash directory.
+All remote files, which are trashed, are moved to the local trash
+directory.  Except remote encrypted files, which are always deleted.
+
++++
+*** New command 'tramp-crypt-add-directory'.
+This command marks a remote directory to contain only encrypted files.
+See the "(tramp) Keeping files encrypted" node of the Tramp manual for
+details.  This feature is experimental.
+
++++
+*** Support of direct asynchronous process invocation.
+When Tramp connection property "direct-async-process" is set to
+non-nil for a given connection, 'make-process' and 'start-file-process'
+calls are performed directly as in "ssh ... <command>".  This avoids
+initialization performance penalties.  See the "(tramp) Improving
+performance of asynchronous remote processes" node of the Tramp manual
+for details, and also for a discussion or restrictions.  This feature
+is experimental.
+
++++
+*** New user option 'tramp-debug-to-file'.
+When non-nil, this user option instructs Tramp to mirror the debug
+buffer to a file under the "/tmp/" directory.  This is useful, if (in
+rare cases) Tramp blocks Emacs, and we need further debug information.
+
++++
+*** Tramp supports lock files now.
+In order to deactivate this, set user option
+'remote-file-name-inhibit-locks' to t.
+
++++
+*** Writing sensitive auto-save, backup or lock files to the local
+temporary directory must be confirmed.  In order to suppress this
+confirmation, set user option 'tramp-allow-unsafe-temporary-files' to
+t.
+
+** Tempo
 
 ---
-*** New faces for heading elements.
-Those are 'shr-h1', 'shr-h2', 'shr-h3', 'shr-h4', 'shr-h5', 'shr-h6'.
+*** 'tempo-define-template' can now re-assign templates to tags.
+Previously, assigning a new template to an already defined tag had no
+effect.
 
-** MH-E mail handler for Emacs
+** gdb-mi
 
-Functions and variables related to handling junk mail have been
-renamed to not associate color with sender quality.
+*** New user option 'gdb-registers-enable-filter'.
+If non-nil, apply a register filter based on
+'gdb-registers-filter-pattern-list'.
 
 +++
-*** New names for mh-junk interactive functions.
-Function 'mh-junk-whitelist' is renamed 'mh-junk-allowlist'.
-Function 'mh-junk-blacklist' is renamed 'mh-junk-blocklist'.
+*** gdb-mi can now store and restore window configurations.
+Use 'gdb-save-window-configuration' to save window configuration to a
+file and 'gdb-load-window-configuration' to load from a file.  These
+commands can also be accessed through the menu bar under "Gud =>
+GDB-Windows".  'gdb-default-window-configuration-file', when non-nil,
+is loaded when GDB starts up.
 
 +++
-*** New binding for 'mh-junk-allowlist'.
-The key binding for 'mh-junk-allowlist' is changed from 'J w' to 'J a'.
-The old binding is supported but warns that it is obsolete.
+*** gdb-mi can now restore window configuration after quit.
+Set 'gdb-restore-window-configuration-after-quit' to non-nil and Emacs
+will remember the window configuration before GDB started and restore
+it after GDB quits.  A toggle button is also provided under "Gud =>
+GDB-Windows".
 
 +++
-*** New names for some hooks.
-'mh-whitelist-msg-hook' is renamed 'mh-allowlist-msg-hook'.
-'mh-blacklist-msg-hook' is renamed 'mh-blocklist-msg-hook'.
+*** gdb-mi now has a better logic for displaying source buffers.
+Now GDB only uses one source window to display source file by default.
+Customize 'gdb-max-source-window-count' to use more than one window.
+Control source file display by 'gdb-display-source-buffer-action'.
 
 +++
-*** New names for some variables.
-Variable 'mh-whitelist-preserves-sequences-flag' is renamed
-'mh-allowlist-preserves-sequences-flag'.
+*** The default value of 'gdb-mi-decode-strings' is now t.
+This means that the default coding-system is now used to decode strings
+and source file names from GDB.
+
+** Compilation mode
+
+---
+*** New function 'ansi-color-compilation-filter'.
+This function is meant to be used in 'compilation-filter-hook'.
+
+---
+*** New user option 'ansi-color-for-compilation-mode'.
+This controls what 'ansi-color-compilation-filter' does.
+
+*** Regexp matching of messages is now case-sensitive by default.
+The variable 'compilation-error-case-fold-search' can be set for
+case-insensitive matching of messages when the old behavior is
+required, but the recommended solution is to use a correctly matching
+regexp instead.
+
+---
+*** New user option 'compilation-search-all-directories'.
+When doing parallel builds, directories and compilation errors may
+arrive in the "*compilation*" buffer out-of-order.  If this variable is
+non-nil (the default), Emacs will now search backwards in the buffer

+'C-c C-c C-f' (next end), 'C-c C-c C-b' (previous end),
+'C-c C-c C-n' (next start) and 'C-c C-c C-p' (previous start), as well
+as 'C-c .', which will alternate between the start and the end of the
+current environment.

+Its default value matches localized abbreviations of the "reply"
+prefix on the Subject line in various languages.

+---
+*** New user option 'shr-offer-extend-specpdl'.
+If this is nil, rendering of HTML in the email message body that
+requires to enlarge 'max-specpdl-size', the number of Lisp variable
+bindings, will be aborted, and Emacs will not ask you whether to
+enlarge 'max-specpdl-size' to complete the rendering.  The default is
+t, which preserves the original behavior.

-
-*** The JSON functions 'json-serialize', 'json-insert',

+
+** In 'nroff-mode', 'center-line' is now bound to 'M-o M-s'.
+The original key binding was 'M-s', which interfered with I-search,
+since the latter uses 'M-s' as a prefix key of the search prefix map.
+
+** In 'f90-mode', the backslash character ('\') no longer escapes.
+For about a decade, the backslash character has no longer had a

+
+* Incompatible Lisp Changes in Emacs 28.1
+
+---
+** Some floating-point numbers are now handled differently by the Lisp reader.
+In previous versions of Emacs, numbers with a trailing dot and an exponent
+were read as integers and the exponent ignored: 2.e6 was interpreted as the
+integer 2.  Such numerals are now read as floats with the exponent included:
+2.e6 is now read as the floating-point value 2000000.0.
+That is, '(read-from-string "1.e3")' => '(1000.0 . 4)' now.
+
+** 'equal' no longer examines some contents of window configurations.
+Instead, it considers window configurations to be equal only if they
+are 'eq'.  To compare contents, use 'compare-window-configurations'
+instead.  This change helps fix a bug in 'sxhash-equal', which returned
+incorrect hashes for window configurations and some other objects.
+
++++
+** The 'lexical-binding' local variable is always enabled.
+Previously, if 'enable-local-variables' was nil, a 'lexical-binding'
+local variable would not be heeded.  This has now changed, and a file
+with a 'lexical-binding' cookie is always heeded.  To revert to the
+old behavior, set 'permanently-enabled-local-variables' to nil.
+
+---
+** 'kill-all-local-variables' has changed how it handles non-symbol hooks.
+The function is documented to eliminate all buffer-local bindings
+except variables with a 'permanent-local' property, or hooks that
+have elements with a 'permanent-local-hook' property.  In addition, it
+would also keep lambda expressions in hooks sometimes.  The latter has
+now been changed: The function will now also remove these.
+
++++
+** Temporary buffers no longer run certain buffer hooks.
+The macros 'with-temp-buffer' and 'with-temp-file' no longer run the
+hooks 'kill-buffer-hook', 'kill-buffer-query-functions', and
+'buffer-list-update-hook' for the temporary buffers they create.  This
+avoids slowing them down when a lot of these hooks are defined.
+
+** New face 'child-frame-border' and frame parameter 
'child-frame-border-width'.
+The face and width of child frames borders can now be determined
+separately from those of normal frames.  To minimize backward
+incompatibility, child frames without a 'child-frame-border-width'
+parameter will fall back to using 'internal-border-width'.  However,
+the new 'child-frame-border' face does constitute a breaking change
+since child frames' borders no longer use the 'internal-border' face.
+
+---
+** 'run-at-time' now tries harder to implement the t TIME parameter.
+If TIME is t, the timer runs at an integral multiple of REPEAT.
+(I.e., if given a REPEAT of 60, it'll run at 08:11:00, 08:12:00,
+08:13:00.)  However, when a machine goes to sleep (or otherwise didn't
+get a time slot to run when the timer was scheduled), the timer would
+then fire every 60 seconds after the time the timer was fired.  This
+has now changed, and the timer code now recomputes the integral
+multiple every time it runs, which means that if the laptop wakes at
+08:16:43, it'll fire at that time, but then at 08:17:00, 08:18:00...
+
+---
+** 'parse-partial-sexp' now signals an error if TO is smaller than FROM.
+Previously this would lead to the function interpreting FROM as TO and
+vice versa, which would be confusing when passing in OLDSTATE, which
+refers to the old state at FROM.
+
++++
+** 'global-mode-string' constructs should end with a space.
+This was previously not formalized, which led to combinations of modes
+displaying data "smushed together" on the mode line.
+
++++
+** 'overlays-in' now handles zero-length overlays slightly differently.
+Previously, zero-length overlays at the end of the buffer were included
+in the result (if the region queried for stopped at that position).
+The same was not the case if the buffer had been narrowed to exclude
+the real end of the buffer.  This has now been changed, and
+zero-length overlays at `point-max' are always included in the results.
+
+---
+** 'replace-match' now runs modification hooks slightly later.
+The function is documented to leave point after the replacement text,
+but this was not always the case if a modification hook inserted text
+in front of the replaced text -- 'replace-match' would instead leave
+point where the end of the inserted text would have been before the
+hook ran.  'replace-match' now always leaves point after the
+replacement text.
+
++++
+** 'completing-read-default' sets completion variables buffer-locally.
+'minibuffer-completion-table' and related variables are now set buffer-locally
+in the minibuffer instead of being set via a global let-binding.
+
+** XML serialization functions now reject invalid characters.
+Previously 'xml-print' would produce invalid XML when given a string
+with characters that are not valid in XML (see
+https://www.w3.org/TR/xml/#charsets).  Now it rejects such strings.
+
+
+---
+** JSON number parsing is now stricter.
+Numbers with a leading plus sign, leading zeros, or a missing integer
+component are now rejected by 'json-read' and friends.  This makes
+them more compliant with the JSON specification and consistent with
+the native JSON parsing functions.
+
+** The JSON functions 'json-serialize', 'json-insert',
+'json-parse-string', and 'json-parse-buffer' now implement some of the
+semantics of RFC 8259 instead of the earlier RFC 4627.  In particular,
+these functions now accept top-level JSON values that are neither
+arrays nor objects.
+
+---
+** Some JSON encoding functions are now obsolete.
+The functions 'json-encode-number', 'json-encode-hash-table',
+'json-encode-key', and 'json-encode-list' are now obsolete.
+
+The first two are kept as aliases of 'json-encode', which should be
+used instead.  Uses of 'json-encode-list' should be changed to call
+one of 'json-encode', 'json-encode-alist', 'json-encode-plist', or
+'json-encode-array' instead.
+
++++
+** Native JSON functions now signal an error if libjansson is unavailable.
+This affects 'json-serialize', 'json-insert', 'json-parse-string',
+and 'json-parse-buffer'.  This can happen if Emacs was compiled with
+libjansson, but the DLL cannot be found and/or loaded by Emacs at run
+time.  Previously, Emacs would display a message and return nil in
+these cases.
+
++++
+** The use of positional arguments in 'define-minor-mode' is obsolete.
+These were actually rendered obsolete in Emacs 21 but were never
+marked as such.
+
+** 'pcomplete-ignore-case' is now an obsolete alias of 
'completion-ignore-case'.
+
+** 'completions-annotations' face is not used when the caller puts own face.
+This affects the suffix specified by completion 'annotation-function'.
+
++++
+** An active minibuffer now has major mode 'minibuffer-mode', not the
+erroneous 'minibuffer-inactive-mode' it formerly had.
+
+** When its first argument is a string, 'make-text-button' no longer
+modifies the string's text properties; instead, it uses and returns
+a copy of the string.  This helps avoid trouble when strings are
+shared or constants.
+
++++
+** Some properties from completion tables are now preserved.
+If 'minibuffer-allow-text-properties' is non-nil, doing completion
+over a table of strings with properties will no longer remove all the
+properties before returning.  This affects things like 'completing-read'.
+
+** 'dns-query' now consistently uses Lisp integers to represent integers.
+Formerly it made an exception for integer components of SOA records,
+because SOA serial numbers can exceed fixnum ranges on 32-bit platforms.
+Emacs now supports bignums so this old glitch is no longer needed.
+
++++
+** The '&define' keyword in an Edebug specification now disables backtracking.
+The implementation was buggy, and multiple '&define' forms in an '&or'
+form should be exceedingly rare.  See the Info node "(elisp) Backtracking" in
+the Emacs Lisp reference manual for background.
+
++++
+** The error 'ftp-error' belongs also to category 'remote-file-error'.
+
+** The WHEN argument of 'make-obsolete' and related functions is mandatory.
+The use of those functions without a WHEN argument was marked obsolete
+back in Emacs 23.1.  The affected functions are: 'make-obsolete',
+'define-obsolete-function-alias', 'make-obsolete-variable',
+'define-obsolete-variable-alias'.
+
++++
+** 'inhibit-nul-byte-detection' is renamed to 'inhibit-null-byte-detection'.
+
+---
+** Some functions are no longer considered safe by 'unsafep':
+'replace-regexp-in-string', 'catch', 'throw', 'error', 'signal'
+and 'play-sound-file'.

+---
+** 'ruby-use-smie' is declared obsolete.
+SMIE is now always enabled and 'ruby-use-smie' only controls whether
+indentation is done using SMIE or with the old ad-hoc code.
+
+---
+** 'sql-*-statement-starters' are no longer user options.
+These variables describe facts about the SQL standard and
+product-specific additions.  There should be no need for users to
+customize them.
+
+** The Lisp variables 'previous-system-messages-locale' and
+'previous-system-time-locale' have been removed, as they were created
+by mistake and were not useful to Lisp code.
+
+---
+** Function 'lm-maintainer' is replaced with 'lm-maintainers'.
+The former is now declared obsolete.
+
+** 'facemenu.el' is no longer preloaded.
+To use functions/variables from the package, you now have to say
+'(require 'facemenu)' or similar.
+
+** 'facemenu-color-alist' is now obsolete, and is not used.
+
+** The variable 'keyboard-type' is obsolete and not dynamically scoped any 
more.
+
++++
+** The 'values' variable is now obsolete.
+Using it just contributes to the growth of the Emacs memory
+footprint.
+
+---
+** The 'load-dangerous-libraries' variable is now obsolete.
+It was used to allow loading Lisp libraries compiled by XEmacs, a
+modified version of Emacs which is no longer actively maintained.
+This is no longer supported, and setting this variable has no effect.
+
++++
+** The macro 'with-displayed-buffer-window' is now obsolete.
+Use macro 'with-current-buffer-window' with action alist entry 'body-function'.
+
+---
+** The rfc2368.el library is now obsolete.
+Use rfc6068.el instead.  The main difference is that
+'rfc2368-parse-mailto-url' and 'rfc2368-unhexify-string' assumed that
+the strings were all-ASCII, while 'rfc6068-parse-mailto-url' and
+'rfc6068-unhexify-string' parse UTF-8 strings.
+
+---
+** The inversion.el library is now obsolete.
+
+---
+** The metamail.el library is now obsolete.
+
+** Edebug changes
+
+---
+*** 'get-edebug-spec' is obsolete, replaced by 'edebug-get-spec'.
+
++++
+*** The spec operator ':name NAME' is obsolete, use '&name' instead.
+
++++
+*** The spec element 'function-form' is obsolete, use 'form' instead.
+
++++
+*** New function 'def-edebug-elem-spec' to define Edebug spec elements.
+These used to be defined with 'def-edebug-spec' thus conflating the
+two name spaces, which lead to name collisions.
+The use of 'def-edebug-spec' to define Edebug spec elements is
+declared obsolete.
+
+---
+** The sb-image.el library is now obsolete.
+This was a compatibility kludge which is no longer needed.
+
+---
+** Some libraries obsolete since Emacs 23 have been removed:
+ledit.el, lmenu.el, lucid.el and old-whitespace.el.

+'gnus-article-hide-pgp-hook', 'gnus-inews-mark-gcc-as-read',
+'gnus-treat-display-xface', 'gnus-treat-strip-pgp',
+'nnmail-spool-file'.
 
-** In 'f90-mode', the backslash character ('\') no longer escapes.
-For about a decade, the backslash character has no longer had a
-special escape syntax in Fortran F90.  To get the old behavior back,
-say something like:
+---
+** The obsolete function 'thread-alive-p' has been removed.
 
-    (modify-syntax-entry ?\\ "\\" f90-mode-syntax-table)
+---
+** The variable 'force-new-style-backquotes' has been removed.
+This removes the final remaining trace of old-style backquotes.
 
-** In 'nroff-mode', 'center-line' is now bound to 'M-o M-s'.
-The original key binding was 'M-s', which interfered with I-search,
-since the latter uses 'M-s' as a prefix key of the search prefix map.
+---
+** Some obsolete variable and function aliases in dbus.el have been removed.
+In Emacs 24.3, the variable 'dbus-event-error-hooks' was renamed to
+'dbus-event-error-functions' and the function
+'dbus-call-method-non-blocking' was renamed to 'dbus-call-method'.
+The old names, which were kept as obsolete aliases of the new names,
+have now been removed.
 
-** 'vc-print-branch-log' shows the change log for BRANCH from its root
-directory instead of the default directory.
+
+* Lisp Changes in Emacs 28.1
 
----
-** 'project-shell' and 'shell' now use 'pop-to-buffer-same-window'.
-This is to keep the same behavior as Eshell.
++++
+** The 'interactive' syntax has been extended to allow listing applicable 
modes.
+Forms like '(interactive "p" dired-mode)' can be used to annotate the
+commands as being applicable for modes derived from 'dired-mode',
+or if the mode is a minor mode, that the current buffer has that
+minor mode activated.  Note that using this form will create byte code
+that is not compatible with byte code in previous Emacs versions.
 
-** The escape sequence '\e[29~' in Xterm is now mapped to 'menu'.
-Xterm sends this sequence for both 'F16' and 'Menu' keys
-It used to be mapped to 'print' but we couldn't find a terminal
-that uses this sequence for any kind of 'Print' key.
-This makes the Menu key (see https://en.wikipedia.org/wiki/Menu_key)
-work for `context-menu-mode` in Xterm.
++++
+** New forms to declare how completion should happen has been added.
+'(declare (completion PREDICATE))' can be used as a general predicate
+to say whether the command should be present when completing with
+'M-x TAB'.  '(declare (modes MODE...))' can be used as a short-hand
+way of saying that the command should be present when completing from
+buffers in major modes derived from MODE..., or, if it's a minor mode,
+whether that minor mode is enabled in the current buffer.
 
----
-** New user option 'xterm-store-paste-on-kill-ring'.
-If non-nil (the default), Emacs pushes pasted text onto the kill ring
-(if using an xterm-like terminal that supports bracketed paste).
-Setting this to nil inhibits that.
++++
+** 'define-minor-mode'  now takes an ':interactive' argument.
+This can be used for specifying which modes this minor mode is meant
+for, or to make the new minor mode non-interactive.  The default value
+is t.
 
-
-* Incompatible Lisp Changes in Emacs 28.1
++++
+** 'define-derived-mode' now takes an ':interactive' argument.
+This can be used to control whether the defined mode is a command
+or not, and is useful when defining commands that aren't meant to be
+used by users directly.
 
----
-** 'run-at-time' now tries harder to implement the t TIME parameter.
-If TIME is t, the timer runs at an integral multiple of REPEAT.
-(I.e., if given a REPEAT of 60, it'll run at 08:11:00, 08:12:00,
-08:13:00.)  However, when a machine goes to sleep (or otherwise didn't
-get a time slot to run when the timer was scheduled), the timer would
-then fire every 60 seconds after the time the timer was fired.  This
-has now changed, and the timer code now recomputes the integral
-multiple every time it runs, which means that if the laptop wakes at
-08:16:43, it'll fire at that time, but then at 08:17:00, 08:18:00...
++++
+** 'define-globalized-minor-mode' now takes a ':predicate' parameter.
+This can be used to control which major modes the minor mode should be
+used in.
 
----
-** 'parse-partial-sexp' now signals an error if TO is smaller than FROM.
-Previously this would lead to the function interpreting FROM as TO and
-vice versa, which would be confusing when passing in OLDSTATE, which
-refers to the old state at FROM.
++++
+** 'condition-case' now allows for a success handler.
+It is written as '(:success BODY...)' where BODY is executed
+whenever the protected form terminates without error, with the
+specified variable bound to the the value of the protected form.
 
 +++
-** 'overlays-in' now handles zero-length overlays slightly differently.
-Previously, zero-length overlays at the end of the buffer were included
-in the result (if the region queried for stopped at that position).
-The same was not the case if the buffer had been narrowed to exclude
-the real end of the buffer.  This has now been changed, and
-zero-length overlays at `point-max' are always included in the results.
+** A function can now be thrown to the 'exit' label in addition to t or nil.
+The command loop will call it with zero arguments before returning.
 
----
-** 'replace-match' now runs modification hooks slightly later.
-The function is documented to leave point after the replacement text,
-but this was not always the case if a modification hook inserted text
-in front of the replaced text -- 'replace-match' would instead leave
-point where the end of the inserted text would have been before the
-hook ran.  'replace-match' now always leaves point after the
-replacement text.
++++
+** The behavior of 'format-spec' is now closer to that of 'format'.
+In order for the two functions to behave more consistently,
+'format-spec' now pads and truncates based on string width rather than
+length, and also supports format specifications that include a
+truncating precision field, such as "%.2a".
 
 ---
-** 'kill-all-local-variables' has changed how it handles non-symbol hooks.
-The function is documented to eliminate all buffer-local bindings
-except variables with a 'permanent-local' property, or hooks that
-have elements with a 'permanent-local-hook' property.  In addition, it
-would also keep lambda expressions in hooks sometimes.  The latter has
-now been changed: The function will now also remove these.
+** 'defvar' detects the error of defining a variable currently lexically bound.
+Such mixes are always signs that the outer lexical binding was an
+error and should have used dynamic binding instead.
 
 ---
-** Some floating-point numbers are now handled differently by the Lisp reader.
-In previous versions of Emacs, numbers with a trailing dot and an exponent
-were read as integers and the exponent ignored: 2.e6 was interpreted as the
-integer 2.  Such numerals are now read as floats with the exponent included:
-2.e6 is now read as the floating-point value 2000000.0.
-That is, '(read-from-string "1.e3")' => '(1000.0 . 4)' now.
+** New variable 'inhibit-mouse-event-check'.
+If bound to non-nil, a command with '(interactive "e")' doesn't signal
+an error when invoked by input event that is not a mouse click (e.g.,
+a key sequence).
 
 +++
-** The 'lexical-binding' local variable is always enabled.
-Previously, if 'enable-local-variables' was nil, a 'lexical-binding'
-local variable would not be heeded.  This has now changed, and a file
-with a 'lexical-binding' cookie is always heeded.  To revert to the
-old behavior, set 'permanently-enabled-local-variables' to nil.
+** Doc strings can now link to customization groups.
+Text like "customization group `whitespace'" will be made into a
+button.  When clicked, it'll take the user to a Custom buffer
+displaying that customization group.
 
 +++
-** 'completing-read-default' sets completion variables buffer-locally.
-'minibuffer-completion-table' and related variables are now set buffer-locally
-in the minibuffer instead of being set via a global let-binding.
+** Buffers can now be created with certain hooks disabled.
+The functions 'get-buffer-create' and 'generate-new-buffer' accept a
+new optional argument INHIBIT-BUFFER-HOOKS.  If non-nil, the new
+buffer does not run the hooks 'kill-buffer-hook',
+'kill-buffer-query-functions', and 'buffer-list-update-hook'.  This
+avoids slowing down internal or temporary buffers that are never
+presented to users or passed on to other applications.
 
 +++
-** The use of positional arguments in 'define-minor-mode' is obsolete.
-These were actually rendered obsolete in Emacs 21 but were never
-marked as such.
-
-** 'facemenu-color-alist' is now obsolete, and is not used.
+** New command 'make-directory-autoloads'.
+This does the same as the old command 'update-directory-autoloads',
+but has different semantics: Instead of passing in the output file via
+the dynamically bound 'generated-autoload-file' variable, the output
+file is now a explicit parameter.
 
-** 'facemenu.el' is no longer preloaded.
-To use functions/variables from the package, you now have to say
-'(require 'facemenu)' or similar.
+---
+** Dragging a file to Emacs will now also push the name of the file
+onto 'file-name-history'.
 
-** 'pcomplete-ignore-case' is now an obsolete alias of 
'completion-ignore-case'.
+---
+** The 'easymenu' library is now preloaded.
 
-** 'completions-annotations' face is not used when the caller puts own face.
-This affects the suffix specified by completion 'annotation-function'.
+---
+** The 'iso-transl' library is now preloaded.
+This means that keystrokes like 'Alt-[' are defined by default,
+instead of only becoming available after doing (for instance)
+'C-x 8 <letter>'.
 
-** 'set-process-buffer' now updates the process mark.
-The mark will be set to point to the end of the new buffer.
+---
+** ':safe' settings in 'defcustom' are now propagated to the loaddefs files.
 
 +++
-** An active minibuffer now has major mode 'minibuffer-mode', not the
-erroneous 'minibuffer-inactive-mode' it formerly had.
+** ERT can now output more verbose test failure reports.
+If the 'EMACS_TEST_VERBOSE' environment variable is set, failure
+summaries will include the failing condition.
+
+** Byte compiler changes
 
 +++
-** Some properties from completion tables are now preserved.
-If 'minibuffer-allow-text-properties' is non-nil, doing completion
-over a table of strings with properties will no longer remove all the
-properties before returning.  This affects things like 'completing-read'.
+*** New byte-compiler check for missing dynamic variable declarations.
+It is meant as an (experimental) aid for converting Emacs Lisp code
+to lexical binding, where dynamic (special) variables bound in one
+file can affect code in another.  For details, see the manual section
+"(elisp) Converting to Lexical Binding".
 
-** 'equal' no longer examines some contents of window configurations.
-Instead, it considers window configurations to be equal only if they
-are 'eq'.  To compare contents, use 'compare-window-configurations'
-instead.  This change helps fix a bug in 'sxhash-equal', which returned
-incorrect hashes for window configurations and some other objects.
++++
+*** 'byte-recompile-directory' can now compile symlinked ".el" files.
+This is achieved by giving a non-nil FOLLOW-SYMLINKS parameter.
 
-** When its first argument is a string, 'make-text-button' no longer
-modifies the string's text properties; instead, it uses and returns
-a copy of the string.  This helps avoid trouble when strings are
-shared or constants.
+---
+*** The byte-compiler now warns about too wide documentation strings.
+By default, it will warn if a documentation string is wider than the
+largest of 'byte-compile-docstring-max-column' or 'fill-column'
+characters.
 
 +++
-** Temporary buffers no longer run certain buffer hooks.
-The macros 'with-temp-buffer' and 'with-temp-file' no longer run the
-hooks 'kill-buffer-hook', 'kill-buffer-query-functions', and
-'buffer-list-update-hook' for the temporary buffers they create.  This
-avoids slowing them down when a lot of these hooks are defined.
+*** 'byte-compile-file' optional argument LOAD is now obsolete.
+To load the file after byte-compiling, add a call to 'load' from Lisp
+or use 'M-x emacs-lisp-byte-compile-and-load' interactively.
 
-** New face 'child-frame-border' and frame parameter 
'child-frame-border-width'.
-The face and width of child frames borders can now be determined
-separately from those of normal frames.  To minimize backward
-incompatibility, child frames without a 'child-frame-border-width'
-parameter will fall back to using 'internal-border-width'.  However,
-the new 'child-frame-border' face does constitute a breaking change
-since child frames' borders no longer use the 'internal-border' face.
+** Macroexp
+---
+*** New function 'macroexp-file-name' to know the name of the current file.
+---
+*** New function 'macroexp-compiling-p' to know if we're compiling.
+---
+*** New function 'macroexp-warn-and-return' to help emit warnings.
+This used to be named 'macroexp--warn-and-return' and has proved useful
+and well-behaved enough to lose the "internal" marker.
+
+** map.el
+
+*** Pcase 'map' pattern added keyword symbols abbreviation.
+A pattern like '(map :sym)' binds the map's value for ':sym' to 'sym',
+equivalent to '(map (:sym sym))'.
 
 ---
-** The obsolete function 'thread-alive-p' has been removed.
+*** The function 'map-copy' now uses 'copy-alist' on alists.
+This is a slightly deeper copy than the previous 'copy-sequence'.
 
-** 'dns-query' now consistently uses Lisp integers to represent integers.
-Formerly it made an exception for integer components of SOA records,
-because SOA serial numbers can exceed fixnum ranges on 32-bit platforms.
-Emacs now supports bignums so this old glitch is no longer needed.
+---
+*** The function 'map-contains-key' now supports plists.
 
 ---
-** The new function 'dns-query-asynchronous' has been added.
-It takes the same parameters as 'dns-query', but adds a callback
-parameter.
+*** More consistent duplicate key handling in 'map-merge-with'.
+Until now, 'map-merge-with' promised to call its function argument
+whenever multiple maps contained 'eql' keys.  However, this did not
+always coincide with the keys that were actually merged, which could
+be 'equal' instead.  The function argument is now called whenever keys
+are merged, for greater consistency with 'map-merge' and 'map-elt'.
 
-** The Lisp variables 'previous-system-messages-locale' and
-'previous-system-time-locale' have been removed, as they were created
-by mistake and were not useful to Lisp code.
+** pcase
 
----
-** The 'load-dangerous-libraries' variable is now obsolete.
-It was used to allow loading Lisp libraries compiled by XEmacs, a
-modified version of Emacs which is no longer actively maintained.
-This is no longer supported, and setting this variable has no effect.
++++
+*** The 'or' pattern now binds the union of the vars of its sub-patterns.
+If a variable is not bound by the subpattern that matched, it gets bound
+to nil.  This was already sometimes the case, but it is now guaranteed.
 
 +++
-** The macro 'with-displayed-buffer-window' is now obsolete.
-Use macro 'with-current-buffer-window' with action alist entry 'body-function'.
+*** The 'pred' pattern can now take the form '(pred (not FUN))'.
+This is like '(pred (lambda (x) (not (FUN x))))' but results
+in better code.
 
 ---
-** The inversion.el library is now obsolete.
+*** New function 'pcase-compile-patterns' to write other macros.
 
----
-** The metamail.el library is now obsolete.
+*** Added 'cl-type' pattern.
+The new 'cl-type' pattern compares types using 'cl-typep', which allows
+comparing simple types like '(cl-type integer)', as well as forms like
+'(cl-type (integer 0 10))'.
 
----
-** Some obsolete variable and function aliases in dbus.el have been removed.
-In Emacs 24.3, the variable 'dbus-event-error-hooks' was renamed to
-'dbus-event-error-functions' and the function
-'dbus-call-method-non-blocking' was renamed to 'dbus-call-method'.
-The old names, which were kept as obsolete aliases of the new names,
-have now been removed.
+*** New macro 'pcase-setq'
+This macro is the 'setq' equivalent of 'pcase-let', which allows for
+destructuring patterns in a 'setq' form.
 
----
-** Some libraries obsolete since Emacs 23 have been removed:
-ledit.el, lmenu.el, lucid.el and old-whitespace.el.
+** Edebug specification lists can use some new keywords:

+**** '&interpose SPEC FUN ARGS..' lets FUN control parsing after SPEC.
+More specifically, FUN is called with 'HEAD PF ARGS..' where
+PF is a parsing function that expects a single argument (the specs to

----
-** Some functions and variables obsolete since Emacs 22 have been removed:
-'gnus-article-hide-pgp-hook', 'gnus-inews-mark-gcc-as-read',
-'gnus-treat-display-xface', 'gnus-treat-strip-pgp',
-'nnmail-spool-file'.
++++
+**** '&error MSG' unconditionally aborts the current edebug instrumentation.
 
-** The WHEN argument of 'make-obsolete' and related functions is mandatory.
-The use of those functions without a WHEN argument was marked obsolete
-back in Emacs 23.1.  The affected functions are: 'make-obsolete',
-'define-obsolete-function-alias', 'make-obsolete-variable',
-'define-obsolete-variable-alias'.
++++
+**** '&name SPEC FUN' extracts the current name from the code matching SPEC.
 
-** The variable 'keyboard-type' is obsolete and not dynamically scoped any 
more.
+** Dynamic modules changes
 
 +++
-** The 'values' variable is now obsolete.
-Using it just contributes to the growth of the Emacs memory
-footprint.
+*** The module header 'emacs-module.h' now contains type aliases
+'emacs_function' and 'emacs_finalizer' for module functions and
+finalizers, respectively.
 
 +++
-** The '&define' keyword in an Edebug specification now disables backtracking.
-The implementation was buggy, and multiple '&define' forms in an '&or'
-form should be exceedingly rare.  See the Info node "(elisp) Backtracking" in
-the Emacs Lisp reference manual for background.
-
----
-** 'sql-*-statement-starters' are no longer user options.
-These variables describe facts about the SQL standard and
-product-specific additions.  There should be no need for users to
-customize them.
+*** Module functions can now be made interactive.
+Use 'make_interactive' to give a module function an interactive
+specification.
 
----
-** Function 'lm-maintainer' is replaced with 'lm-maintainers'.
-The former is now declared obsolete.
++++
+*** Module functions can now install an optional finalizer that is
+called when the function object is garbage-collected.  Use
+'set_function_finalizer' to set the finalizer and
+'get_function_finalizer' to retrieve it.
 
-
-* Lisp Changes in Emacs 28.1
++++
+*** Modules can now open a channel to an existing pipe process using
+the new module function 'open_channel'.  Modules can use this
+functionality to asynchronously send data back to Emacs.
 
 +++
-*** Doc strings can now link to customization groups.
-Text like "customization group `whitespace'" will be made into a
-button.  When clicked, it'll take the user to a Custom buffer
-displaying that customization group.
+*** A new module API 'make_unibyte_string' is provided.
+It can be used to create Lisp strings with arbitrary byte sequences
+(a.k.a. "raw bytes").
 
 +++
-*** New macro 'with-existing-directory'.
-This macro binds 'default-directory' to some other existing directory
-if 'default-directory' doesn't exist, and then executes the body forms.
+** New function 'string-search'.
+This function takes two string parameters and returns the position of
+the first instance of the former string in the latter.
 
 +++
-*** New function 'file-name-concat'.
-This appends file name components to a directory name and returns the
-result.
+** New function 'string-replace'.
+This function works along the line of 'replace-regexp-in-string', but
+matching on strings instead of regexps, and does not change the global
+match state.
 
 +++
-*** New function 'split-string-shell-command'.
+** New function 'split-string-shell-command'.
 This splits a shell command string into separate components,
 respecting quoting with single ('like this') and double ("like this")
 quotes, as well as backslash quoting (like\ this).
 
----
-*** ':safe' settings in 'defcustom' are now propagated to the loaddefs files.
+** New string manipulation functions added to subr-x.el.
+'string-clean-whitespace', 'string-fill', 'string-limit',
+'string-lines', 'string-pad' and 'string-chop-newline'.
 
 +++
-** New function 'syntax-class-to-char'.
-This does almost the opposite of 'string-to-syntax' -- it returns the
-syntax descriptor (a character) given a raw syntax descriptor (an
-integer).
+** New function 'replace-regexp-in-region'.
 
 +++
-** New function 'buffer-local-boundp'.
-This predicate says whether a symbol is bound in a specific buffer.
+** New function 'replace-string-in-region'.
 
----
-** Emacs now attempts to test for high-rate subprocess output more fairly.
-When several subprocesses produce output simultaneously at high rate,
-Emacs will now by default attempt to service them all in a round-robin
-fashion.  Set the new variable 'process-prioritize-lower-fds' to a
-non-nil value to get back the old behavior, whereby after reading
-from a subprocess, Emacs would check for output of other subprocesses
-in a way that is likely to read from the same process again.
++++
+** New function 'file-name-with-extension'.
+This function allows a canonical way to set/replace the extension of a
+file name.
 
 +++
-** New function 'sxhash-equal-including-properties'.
-This is identical to 'sxhash-equal' but accounting also for string
-properties.
+** New function 'file-modes-number-to-symbolic' to convert a numeric
+file mode specification into symbolic form.
 
 +++
-** 'unlock-buffer' displays warnings instead of signaling.
-Instead of signaling 'file-error' conditions for file system level
-errors, the function now calls 'display-warning' and continues as if
-the error did not occur.
+** New function 'file-name-concat'.
+This appends file name components to a directory name and returns the
+result.
+
++++
+** New function 'file-backup-file-names'.
+This function returns the list of file names of all the backup files
+of its file argument.
+
++++
+** New function 'directory-empty-p'.
+This predicate tests whether a given file name is an accessible
+directory and whether it contains no other directories or files.
+
++++
+** New function 'buffer-local-boundp'.
+This predicate says whether a symbol is bound in a specific buffer.
 
 +++
 ** New function 'always'.
 This is identical to 'ignore', but returns t instead.
 
 +++
-** New forms to declare how completion should happen has been added.
-'(declare (completion PREDICATE))' can be used as a general predicate
-to say whether the command should be present when completing with
-'M-x TAB'.  '(declare (modes MODE...))' can be used as a short-hand
-way of saying that the command should be present when completing from
-buffers in major modes derived from MODE..., or, if it's a minor mode,
-whether that minor mode is enabled in the current buffer.
+** New function 'sxhash-equal-including-properties'.
+This is identical to 'sxhash-equal' but accounting also for string
+properties.
 
-+++
-** The 'interactive' syntax has been extended to allow listing applicable 
modes.
-Forms like '(interactive "p" dired-mode)' can be used to annotate the
-commands as being applicable for modes derived from 'dired-mode',
-or if the mode is a minor mode, that the current buffer has that
-minor mode activated.  Note that using this form will create byte code
-that is not compatible with byte code in previous Emacs versions.
+** New function 'buffer-line-statistics'.
+This function returns some statistics about the line lengths in a buffer.
+
+---
+** New function 'color-values-from-color-spec'.
+This can be used to parse RGB color specs in several formats and
+convert them to a list '(R G B)' of primary color values.
 
-+++
-** New buffer-local variable 'local-minor-modes'.
-This permanently buffer-local variable holds a list of currently
-enabled non-global minor modes in the current buffer (as a list of
-symbols).
+---
+** New function 'custom-add-choice'.
+This function can be used by modes to add elements to the
+'choice' customization type of a variable.
 
-+++
-** New variable 'global-minor-modes'.
-This variable holds a list of currently enabled global minor modes (as
-a list of symbols).
+---
+** New function 'decoded-time-period'.
+It interprets a decoded time structure as a period and returns the
+equivalent period in seconds.
 
 +++
-** 'define-minor-mode'  now takes an ':interactive' argument.
-This can be used for specifying which modes this minor mode is meant
-for, or to make the new minor mode non-interactive.  The default value
-is t.
+** New function 'dom-print'.
 
 +++
-** 'define-derived-mode' now takes an ':interactive' argument.
-This can be used to control whether the defined mode is a command
-or not, and is useful when defining commands that aren't meant to be
-used by users directly.
+** New function 'dom-remove-attribute'.
 
 ---
-** The 'easymenu' library is now preloaded.
-
----
-** New variable 'indent-line-ignored-functions'.
-This allows modes to cycle through a set of indentation functions
-appropriate for those modes.
+** New function 'dns-query-asynchronous'.
+It takes the same parameters as 'dns-query', but adds a callback
+parameter.
 
 ** New function 'garbage-collect-maybe' to trigger GC early.
 
 ---
-** 'defvar' detects the error of defining a variable currently lexically bound.
-Such mixes are always signs that the outer lexical binding was an
-error and should have used dynamic binding instead.
+** New function 'get-locale-names'.
+This utility function returns a list of locale names on the current
+system.
 
 +++
-** New completion function 'affixation-function' to add prefix/suffix.
-It accepts a list of completions and should return a list where
-each element is a list with three elements: a completion,
-a prefix string, and a suffix string.
+** New function 'insert-into-buffer'.
+This is like 'insert-buffer-substring', but works in the opposite
+direction.
 
 +++
-** New completion function 'group-function' for grouping candidates.
-It takes two arguments: a completion candidate and a 'transform' flag.
+** New function 'json-available-p'.
+This predicate returns non-nil if Emacs is built with libjansson
+support, and it is available on the current system.
 
-+++
-** 'read-char-from-minibuffer' and 'y-or-n-p' support 'help-form'.
-If you bind 'help-form' to a non-nil value while calling these functions,
-then pressing 'C-h' ('help-char') causes the function to evaluate 'help-form'
-and display the result.
+---
+** New function 'mail-header-parse-addresses-lax'.
+This takes a comma-separated string and returns a list of mail/name
+pairs.
 
 ---
-** New variables 'read-char-choice-use-read-key' and 'y-or-n-p-use-read-key'.
-When non-nil, then functions 'read-char-choice' and 'y-or-n-p' (respectively)
-use the function 'read-key' to read a character instead of using the 
minibuffer.
+** New function 'mail-header-parse-address-lax'.
+Parse a string as a mail address-like string.
 
 ---
-** New user option 'use-short-answers'.
-When non-nil, the function 'y-or-n-p' is used instead of
-'yes-or-no-p'.  This eliminates the need to define an alias that maps
-one to another in the init file.  The same user option also controls
-whether the function 'read-answer' accepts short answers.
+** New function 'make-separator-line'.
+Make a string appropriate for usage as a visual separator line.
 
 +++
-** 'set-window-configuration' now takes two optional parameters,
-'dont-set-frame' and 'dont-set-miniwindow'.  The first of these, when
-non-nil, instructs the function not to select the frame recorded in
-the configuration.  The second prevents the current minibuffer being
-replaced by the one stored in the configuration.
+** New function 'object-intervals'.
+This function returns a copy of the list of intervals (i.e., text
+properties) in the object in question (which must either be a string
+or a buffer).
 
 +++
-** 'define-globalized-minor-mode' now takes a ':predicate' parameter.
-This can be used to control which major modes the minor mode should be
-used in.
+** New function 'process-lines-ignore-status'.
+This is like 'process-lines', but does not signal an error if the
+return status is non-zero.  'process-lines-handling-status' has also
+been added, and takes a callback to handle the return status.
 
 +++
-** 'truncate-string-ellipsis' now uses '…' by default.
-Modes that use 'truncate-string-to-width' with non-nil, non-string
-argument ELLIPSIS, will now indicate truncation using '…' when
-the selected frame can display it, and using "..." otherwise.
+** New function 'require-theme'.
+This function is like 'require', but searches 'custom-theme-load-path'
+instead of 'load-path'.  It can be used by Custom themes to load
+supporting Lisp files when 'require' is unsuitable.
 
 +++
-** 'string-width' now accepts two optional arguments FROM and TO.
-This allows calculating the width of a substring without consing a
-new string.
+** New function 'syntax-class-to-char'.
+This does almost the opposite of 'string-to-syntax' -- it returns the
+syntax descriptor (a character) given a raw syntax descriptor (an
+integer).
 
 +++
-** New command 'make-directory-autoloads'.
-This does the same as the old command 'update-directory-autoloads',
-but has different semantics: Instead of passing in the output file via
-the dynamically bound 'generated-autoload-file' variable, the output
-file is now a explicit parameter.
+** New functions 'null-device' and 'path-separator'.
+These functions return the connection local value of the respective
+variables.  This can be used for remote hosts.
 
 +++
-** New function 'string-search'.
-This function takes two string parameters and returns the position of
-the first instance of the former string in the latter.
+** New predicate functions 'length<', 'length>' and 'length='.
+Using these functions may be more efficient than using 'length' (if
+the length of a (long) list is being computed just to compare this
+length to a number).
 
 +++
-** New function 'string-replace'.
-This function works along the line of 'replace-regexp-in-string', but
-matching on strings instead of regexps, and does not change the global
-match state.
+** New macro 'dlet' to dynamically bind variables.
 
 +++
-** New function 'process-lines-ignore-status'.
-This is like 'process-lines', but does not signal an error if the
-return status is non-zero.  'process-lines-handling-status' has also
-been added, and takes a callback to handle the return status.
-
----
-** 'ascii' is now a coding system alias for 'us-ascii'.
+** New macro 'with-existing-directory'.
+This macro binds 'default-directory' to some other existing directory
+if 'default-directory' doesn't exist, and then executes the body forms.
 
 +++
-** New function 'file-name-with-extension'.
-This function allows a canonical way to set/replace the extension of a
-file name.
+** New variable 'current-minibuffer-command'.
+This is like 'this-command', but it is bound recursively when entering
+the minibuffer.
 
 +++
-** New function 'file-backup-file-names'.
-This function returns the list of file names of all the backup files
-of its file argument.
+** New variable 'inhibit-interaction' to make user prompts signal an error.
+If this is bound to something non-nil, functions like
+'read-from-minibuffer', 'read-char' (and related) will signal an
+'inhibited-interaction' error.
+
+---
+** New variable 'indent-line-ignored-functions'.
+This allows modes to cycle through a set of indentation functions
+appropriate for those modes.
 
 +++
-** New utility function 'directory-empty-p'.
-This predicate tests whether a given file name is an accessible
-directory and whether it contains no other directories or files.
+** New variable 'print-integers-as-characters' modifies integer printing.
+If this variable is non-nil, character syntax is used for printing
+numbers when this makes sense, such as '?A' for 65.
 
 +++
-** 'directory-files' now takes an additional COUNT parameter.
-The parameter makes 'directory-files' return COUNT first file names
-from a directory.  If MATCH is also given, the function will return
-first COUNT file names that match the expression.  The same COUNT
-parameter has been added to 'directory-files-and-attributes'.
+** New variable 'tty-menu-calls-mouse-position-function'.
+This controls whether 'mouse-position-function' is called by functions
+that retrieve the mouse position when that happens during TTY menu
+handling.  Lisp programs that set 'mouse-position-function' should
+also set this variable non-nil if they are compatible with the tty
+menu handling.
 
 +++
-** The 'count-lines' function now takes an optional parameter to
-ignore invisible lines.
+** New variables that hold default buffer names for shell output.
+The new constants 'shell-command-buffer-name' and
+'shell-command-buffer-name-async' store the default buffer names
+for the output of, respectively, synchronous and async shell
+commands.
 
 ---
-** 'count-words' now crosses field boundaries.
-Originally, 'count-words' would stop counting at the first field
-boundary it encountered; now it keeps counting all the way to the
-region's (or buffer's) end.
+** New variables 'read-char-choice-use-read-key' and 'y-or-n-p-use-read-key'.
+When non-nil, then functions 'read-char-choice' and 'y-or-n-p' (respectively)
+use the function 'read-key' to read a character instead of using the 
minibuffer.
 
----
-** New function 'custom-add-choice'.
-This function can be used by modes to add elements to the
-'choice' customization type of a variable.
++++
+** New variable 'global-minor-modes'.
+This variable holds a list of currently enabled global minor modes (as
+a list of symbols).
 
 +++
-** New function 'require-theme'.
-This function is like 'require', but searches 'custom-theme-load-path'
-instead of 'load-path'.  It can be used by Custom themes to load
-supporting Lisp files when 'require' is unsuitable.
+** New buffer-local variable 'local-minor-modes'.
+This permanently buffer-local variable holds a list of currently
+enabled non-global minor modes in the current buffer (as a list of
+symbols).
 
 +++
-** New function 'file-modes-number-to-symbolic' to convert a numeric
-file mode specification into symbolic form.
+** New completion function 'affixation-function' to add prefix/suffix.
+It accepts a list of completions and should return a list where
+each element is a list with three elements: a completion,
+a prefix string, and a suffix string.
 
 +++
-** New macro 'dlet' to dynamically bind variables.
+** New completion function 'group-function' for grouping candidates.
+It takes two arguments: a completion candidate and a 'transform' flag.
+
++++
+** New error symbol 'minibuffer-quit'.
+Signaling it has almost the same effect as 'quit' except that it
+doesn't cause keyboard macro termination.
+
++++
+** New error 'remote-file-error', a subcategory of 'file-error'.
+It is signaled if a remote file operation fails due to internal
+reasons, and could block Emacs.  It does not replace 'file-error'
+signals for the usual cases.  Timers, process filters and process
+functions, which run remote file operations, shall protect themselves
+against this error.
+
+If such an error occurs, please report this as bug via 'M-x report-emacs-bug'.
+Until it is solved you could ignore such errors by performing
+
+    (setq debug-ignored-errors (cons 'remote-file-error debug-ignored-errors))
+
+** New macro 'named-let' added to subr-x.el.
+It provides Scheme's "named let" looping construct.
 
 ---
-** The variable 'force-new-style-backquotes' has been removed.
-This removes the final remaining trace of old-style backquotes.
+** Emacs now attempts to test for high-rate subprocess output more fairly.
+When several subprocesses produce output simultaneously at high rate,
+Emacs will now by default attempt to service them all in a round-robin
+fashion.  Set the new variable 'process-prioritize-lower-fds' to a
+non-nil value to get back the old behavior, whereby after reading
+from a subprocess, Emacs would check for output of other subprocesses
+in a way that is likely to read from the same process again.
 
-** Mode Lines
+** 'set-process-buffer' now updates the process mark.
+The mark will be set to point to the end of the new buffer.
 
 +++
-*** New user options to control the line/column numbers in the mode line.
-'mode-line-position-line-format' is the line number format (when
-'line-number-mode' is on), 'mode-line-position-column-format' is
-the column number format (when 'column-number-mode' is on), and
-'mode-line-position-column-line-format' is the combined format (when
-both modes are on).
+** 'unlock-buffer' displays warnings instead of signaling.
+Instead of signaling 'file-error' conditions for file system level
+errors, the function now calls 'display-warning' and continues as if
+the error did not occur.
 
 +++
-*** New user option 'mode-line-compact'.
-If non-nil, repeating spaces are compressed into a single space.  If
-'long', this is only done when the mode line is longer than the
-current window width (in characters).
+** 'read-char-from-minibuffer' and 'y-or-n-p' support 'help-form'.
+If you bind 'help-form' to a non-nil value while calling these functions,
+then pressing 'C-h' ('help-char') causes the function to evaluate 'help-form'
+and display the result.
 
 +++
-*** 'global-mode-string' constructs should end with a space.
-This was previously not formalized, which led to combinations of modes
-displaying data "smushed together" on the mode line.
-
-** Changes in handling dynamic modules
+** 'read-number' now has its own history variable.
+Additionally, the function now accepts a HIST argument which can be
+used to specify a custom history variable.
 
 +++
-*** The module header 'emacs-module.h' now contains type aliases
-'emacs_function' and 'emacs_finalizer' for module functions and
-finalizers, respectively.
+** 'set-window-configuration' now takes two optional parameters,
+'dont-set-frame' and 'dont-set-miniwindow'.  The first of these, when
+non-nil, instructs the function not to select the frame recorded in
+the configuration.  The second prevents the current minibuffer being
+replaced by the one stored in the configuration.
+
+---
+** 'count-windows' now takes an optional parameter ALL-FRAMES.
+The semantics are as with 'walk-windows'.
 
 +++
-*** Module functions can now be made interactive.
-Use 'make_interactive' to give a module function an interactive
-specification.
+** 'truncate-string-ellipsis' now uses '…' by default.
+Modes that use 'truncate-string-to-width' with non-nil, non-string
+argument ELLIPSIS, will now indicate truncation using '…' when
+the selected frame can display it, and using "..." otherwise.

-** The new function 'dom-remove-attribute' has been added.
+** 'format-seconds' can now be used for sub-second times.
