Version 0.2.0 on 2022-05-09
═══════════════════════════

  ⁃ Fontaine can apply its changes on a per-frame basis.  One frame may,
    for example, use a preset of font configurations for the purposes of
    a "presentation" while the other has a "small" setup.  Concretely,
    invoke the commands `fontaine-set-preset' and
    `fontaine-set-face-font' with a universal prefix argument (`C-u').
    Without a prefix argument, these commands apply to all frames (as it
    was before).

  ⁃ The `fontaine-presets' accepts a special `t' preset which provides
    "shared fallback values" for all presets.  The manual has a section
    titled "Shared and implicit fallback values for presets" which
    covers all permutations of `fontaine-presets' at length.  The gist
    is that the user can write more concise presets.  Thanks to Ted Reed
    for proposing the idea and testing my prototype in the mailing list:
    
<https://lists.sr.ht/~protesilaos/fontaine/%3C87y1zcmo67.fsf@zenithia.net%3E>.

  ⁃ Simplified the sample configuration on how to restore the latest
    saved value or fall back to a preferred preset.  Thanks to
    Christopher League for proposing an elegant expression over at the
    mailing list:
    
<https://lists.sr.ht/~protesilaos/fontaine/%3C87sfpop0dm.fsf@contrapunctus.net%3E#%3C87pmksoyv6.fsf@contrapunctus.net%3E>

  ⁃ The `fontaine-latest-state-file' is now handled by the package
    `no-littering'.  Thanks to Christopher League for adding it there:
    
<https://github.com/emacscollective/no-littering/commit/76b7335202a5b6ddc6b6798a2e2fd5b09df57dc2>

  ⁃ The new user option `fontaine-font-families' specifies the preferred
    font families that are provided as completion candidates of the
    command `fontaine-set-face-font'.  If left to its default nil value,
    Fontaine tries to find relevant fonts from the underlying system,
    though this is not always accurate depending on the build of Emacs
    and where it runs in.

  ⁃ The doc string of `fontaine-presets' mentions some important caveats
    or information about font settings in emacs.  Thanks to Eli
    Zaretskii for the feedback on the emacs-devel mailing list:
    <https://lists.gnu.org/archive/html/emacs-devel/2022-04/msg01281.html>.


Version 0.1.0 on 2022-04-28
═══════════════════════════

  Initial release of the package.  Please read the manual.

  The core idea for this package was implemented in the `prot-fonts.el'
  file that is part of [my dotfiles] (now deprecated).  I was using it
  at least since November 2020, though the underlying code was probably
  implemented at an earlier date.
