Version 0.3.0 on 2022-03-30
═══════════════════════════

  This release basically contains one major refinement about how buffer
  narrowing is handled.  In detail:

  1. If `logos-outlines-are-pages' is non-nil, it now includes the match
     of the `page-delimiter' regexp in the narrowed region and leaves
     point right after the `page-delimiter'—so in Org mode, after the
     stars.  (It is better to leave point there than at the very
     beginning of the narrowed buffer to match the behavior of
     `logos-forward-page-dwim' when the buffer is not narrowed.)  The
     inclusion of the delimiter helps retain any folding functionality
     associated with that line (e.g. Org headings).

  2. To avoid skipping pages in the narrowed case when point is at their
     outer boundaries, `logos' checks if you are right at the start of a
     `page-delimiter' and if so moves past the delimiter in the opposite
     direction of the given motion: so if you are moving back, it puts
     you after the delimiter, and if you are moving forward it puts you
     before the delimiter.  (The bug was that if the point was at
     `point-max' while narrowed and moving forward, it would skip past a
     page and the same in the opposite direction with `point-min'.)

  3. Changed `logos-narrow-dwim' to call `logos--narrow-to-page' instead
     of `narrow-to-page', so that it too includes the `page-delimiter'
     match in the page.

  4. The `logos--page-p' now always checks for the right delimiter,
     which may be that of the outline if `logos-outlines-are-pages' is
     non-nil.  Whereas before it was hard-coded to the generic
     `page-delimiter'.

  Thanks to Omar Antolín Camarena for commit
  `8c2e85033db982ef13a5e041012dc45d86d9de32' which covers the first
  three of the aforementioned points.  The contribution was sent as a
  patch via email.  Omar has already assigned copyright to the Free

Version 0.2.0 on 2022-03-17
═══════════════════════════

  All functions or variables referenced herein have documentation
  strings and are also documented in the manual.

  ⁃ Implemented the user option `logos-olivetti' which is a buffer-local
    variable that is read when `logos-focus-mode' is enabled.  This
    provides the glue code to integrate Logos with `olivetti'.  Olivetti
    is a package by Paul W. Rankin which centres the contents of the
    buffer in its window.

  ⁃ Removed the do-it-yourself snippet that was present in the manual
    for piecing together Logos and Olivetti.  The documentation has been
    updated accordingly.  Users who followed the old method are advised
    to review their configurations.

  ⁃ Abstracted the state handling of the variables and modes that are
    affected by `logos-focus-mode', based on feedback by Daniel Mendler.
    This improves how the code is written and makes it easier to extend
    it.

  ⁃ Introduced the user options `logos-indicate-buffer-boundaries' and
    `logos-buffer-read-only'.  Both are buffer-local and both take
    effect when `logos-focus-mode' is enabled.  The former controls the
    `indicate-buffer-boundaries' while the latter determines whether the
    buffer should be put in a read-only mode.

  ⁃ Changed how user options are declared as buffer-local, by using the
    appropriate keyword of `defcustom'.  Thanks to Philip Kaludercic for
    the patch, which was sent via email.

  ⁃ Wrote a node entry on how to write a regular expression that targets
    only specific Org heading levels.  This pertains to user options
    `logos-outlines-are-pages' and `logos-outline-regexp-alist'.
