  Highly accessible themes, conforming with the highest standard for
  colour contrast between background and foreground values (WCAG AAA).
  They also are optimised for users with red-green colour deficiency.

  advanced customisations.

5.1.0 on 2025-11-07
═══════════════════

  This version fixes a critical bug in the `modus-themes-with-colors'
  macro. In short, it was not working as before or was not working at
  all. Now it should do the right thing.

  Thanks to Alexandr Semenov for reporting a relevant bug in issue 170
  and for helping me test the results:
  <https://github.com/protesilaos/modus-themes/issues/170>.

  Thanks to Stéphane Marks for testing some configurations with the
  latest stable Emacs version as well as with builds from emacs.git.
  This was done via a private channel and I am sharing this information
  with permission.

  Also thanks to Stefan Monnier for monitoring my commits as I was
  trying to refactor the `modus-themes-with-colors' macro. Some comments
  were posted on the emacs-devel mailing list, as well as a patch that I
  ended up applying and then reverting (check the commit log for the
  technicalities):
  <https://lists.gnu.org/archive/html/emacs-devel/2025-11/msg00114.html>.

  Apologies to everyone for the inconvenience! This was a tricky bug.
  The good thing is that it compelled me to improve several parts of the
  code.

  This version also includes a clarification in the manual about
  building a theme on top of Modus:

  Info manual
        Evaluate `(info "(modus-themes) Build on top of the Modus
        themes")'.

  In short, it mentions that a theme exists in an appropriately named
  file that is part of the `custom-theme-load-path'. Thanks to Ashton
  Wiersdorf for asking a related question in issue 171:
  <https://github.com/protesilaos/modus-themes/issues/171>.


5.0.0 on 2025-11-01
═══════════════════

  This is a major release. There are some small breaking changes. The
  big new feature is that Modus can be used as the basis for other theme
  projects. Two of my other theme packages, the `ef-themes' and the
  `standard-themes' are already done in this way: their next major
  versions will formalise what I have been developing for a while now
  (though the `doric-themes' will remain their own thing for the time
  being).


Build on top of Modus
─────────────────────

  This is of immediate interest to package developers or advanced users.
  It changes nothing for existing users of the Modus themes. Please
  refer to the manual on the matter and feel welcome to contact me if
  you have any questions—I am happy to help.

  Why build on top of Modus? To benefit from (i) the wide face coverage
  and extensive detail-oriented testing, (ii) the use of palette
  mappings, (iii) the palette preview done with
  `modus-themes-list-colors' or related, (iv) the inclusion of the
  derivative theme in the workings of all Modus commands that load a
  theme, like `modus-themes-rotate' and `modus-themes-select' (see the
  new minor mode `modus-themes-include-derivatives-mode').

  Derivative themes can be as simple as a few extra colours on top of,
  say, `modus-operandi'. They can also be more involved, with new
  palette mappings and custom faces that use them. Such themes can …  …
