* Version 9.7 (not released yet)
** Important announcements and breaking changes
*** Org babel backends are now expected to define an additional API function 
~org-babel-session-buffer:<lang>~

Org babel now uses session buffer (if it exists) to retrieve
~default-directory~ environment during src block evaluation.

By default, buffer named like session is checked.  All the backends
that create sessions inside buffers named differently should provide a
function ~org-babel-session-buffer:<lang>~.  The function must accept
two arguments - session name and info list (as returned by
~org-babel-get-src-block-info~); and return the session buffer name.

*** ~org-insert-subheading~ no longer inserts a sub-heading above current when 
point is at the beginning of line

Previously, calling ~org-insert-subheading~ on

: * Heading 1
: <point>* Heading 2

yielded

: * Heading 1
: ** <point>
: * Heading 2

This is no longer the case.  The sub-heading is always created below
current heading (prefix arguments have the same meaning as in
~org-insert-heading~):

: * Heading 1
: * Heading 2
: ** <point>

*** Org mode now fontifies whole table lines (including newline) according to 
~org-table~ face

Previously, leading indentation and trailing newline in table rows
were not fontified using ~org-table~ face.  ~default~ face was used instead.
This made it impossible to scale line height when ~org-table~ face has
smaller height than default (Emacs calculates line height using the tallest 
face).

Now, new ~org-table-row~ face is used on the whole table row lines,
including indentation and the final newline. This face, by default,
inherits from ~org-table~ face.

If the new behavior is not desired, ~org-table-row~ face can be
changed to inherit from ~default~ face.

~org-table~ takes precedence over ~org-table-row~ for the parts of
table rows without indentation and newline.

*** =ox-latex=: ~org-latex-line-break-safe~ is deprecated

~org-latex-line-break-safe~ constant was previously introduced to deal
with edge cases when LaTeX interprets [...] as LaTeX command
argument.  However, it caused a number of other issues and proved
itself not to be as "safe" as it supposed to be.

We now use a Pandoc's approach to deal with the same problem,
utilizing ={[}= to escape =[...]= instances where needed.

*** ob-python now sets ~python-shell-buffer-name~ in Org edit buffers

When editing a Python src block, the editing buffer is now associated
with the Python shell specified by the src block's ~:session~ header,
which means users can now send code directly from the edit buffer,
e.g., using ~C-c C-c~, to the session specified in the Org buffer.

*** ~org-edit-special~ no longer force-starts session in R and Julia source 
blocks

Previously, when R/Julia source block had =:session= header argument
set to a session name with "earmuffs" (like =*session-name*=),
~org-edit-special~ always started a session, if it does not exist.

Now, ~org-edit-special~ arranges that a new session with correct name
is initiated only when user explicitly executes R/Julia-mode commands
that trigger session interactions (requires ESS 24.01.0 or newer).
The same session will remain available in the context of Org babel.

*** It is no longer allowed to tangle into the same file as Org source

Previously, =file.org= with the following contents

: #+begin_src org :tangle file.org
: Text
: #+end_src

would overwrite itself.

Now, an error is thrown.

*** iCalendar export now supports multiline =SUMMARY=, =LOCATION=, and 
=DESCRIPTION= properties

Previously, it was not possible to specify multi-line location,
