+# Bundled emoji data
+
+These are pinned copies of the upstream data files that
+`tools/gen-emoji-data.py` compiles into ZoiteChat's emoji picker catalog
+at build time. Bundling them means every ZoiteChat package exposes the
+same emoji, names, categories and search keywords, independent of the
+GTK runtime version or the emoji data a distribution installs under
+`/usr/share/gtk-3.0/emoji`.
+
+Nothing here affects what is sent over IRC: the picker inserts plain
+Unicode sequences. Official builds register the bundled Noto Color Emoji
+font privately for consistent rendering, while preserving platform font
+fallback if registration is unavailable.

+# Bundled emoji font
+
+`NotoColorEmoji.ttf` reports Noto Color Emoji version 2.051 and covers
+Unicode Emoji 17.0. It is vendored from Debian's
+`fonts-noto-color-emoji` 2.051 package, built from the corresponding
+Google Noto Emoji release.
+
+Every GTK build installs this exact file: Windows (installer and portable
+build files), AppImage, Flatpak and native Meson/RPM builds. It is loaded
+into a private Pango/FreeType font map as `ZoiteChat Emoji`; an older system
+Noto font cannot replace it. No font is installed globally on Windows.
+
+Chat windows and the emoji picker share this map. Fontconfig still loads
+system fonts and configuration for ordinary text, and the configured text
+font, size and style remain in effect. In particular, plain digits, `#`
+and `*` are not assigned emoji metrics.
+
+Windows uses the same FreeType backend rather than GDI registration or an
+OS-version-specific picker. The dependency bundle already ships FreeType,
+Fontconfig and PangoFT2. This rendering path does not require Windows' native
+color-font support. Actual Windows 7 execution still needs testing on that OS.
+
+Meson requires PangoFT2 >= 1.44 and Fontconfig >= 2.13. Normal installations
+load `share/fonts/zoitechat/NotoColorEmoji.ttf` beneath the configured data
+directory; Windows resolves it relative to the executable. AppImage sets
+`ZOITECHAT_EMOJI_FONT` to its own copy. For an uninstalled development build:
+
+```sh
+ZOITECHAT_EMOJI_FONT="$PWD/data/fonts/NotoColorEmoji.ttf" build/src/fe-gtk/zoitechat
+```
+
+A missing/unloadable file logs a warning and retains system-font fallback.
+CI verifies the installed copy and tests catalog/font coverage; AppImage and
+Windows also run the interactive picker regression tests. Native themes,
+DPI and different Pango/Cairo versions can still affect pixel-level output.

-## Read the Docs theme skin
+## HTML theme
 
-The HTML output keeps the existing `basicstrap` Sphinx theme, then applies the
-ZoiteChat main-site skin from `_static/css/zoitechat-docs.css`.
+The `zoitechat` theme inherits Sphinx's built-in `basic` theme. It uses the
+same compact layout, blue navigation, and system fonts as zoitechat.org.
+Appearance starts in System mode on each page. Light and Dark are available
+for the current page; no cookies or browser storage are used.
 
-Brand navigation links are set in `conf.py` through `html_context`, and the
-header logo uses `_static/zoitechat-logo.svg`.
+The theme's templates are in `_theme/zoitechat/`. Its readable CSS and
+JavaScript are in `_static/css/zoitechat-docs.css` and
+`_static/js/zoitechat-docs.js`. No minification, JavaScript package manager,
+external fonts, or CDN assets are required.
+
+Navigation URLs, including `zoite_atlas_url`, are configured through
+`html_context` in `conf.py`. The logo
+is `_static/zoitechat-logo.svg`. Standard Sphinx search, indexes, source
+links, anchors, translations, and previous/next links remain available.
+The HTML output also works as locally installed documentation; project-site
+links only access the network when clicked.
+
+Build from the repository root:
+
+```sh
+sphinx-build -b html docs docs/_build/html
+```
+
+Use a clean output directory when switching themes, so stale Basicstrap
+assets from an earlier build are not included in a package.
+
+## Debian packaging
+
+The active theme does not use the bundled Basicstrap, Bootstrap, jQuery,
+jQuery Cookie, Font Awesome, or icon fonts. Its font stack includes DejaVu
+Sans and DejaVu Sans Mono; no font files are bundled by the theme.
+
+Packagers may exclude `docs/_theme/basicstrap/` from the source package.
+The default theme continues to build without that directory. No pre-minified
+third-party assets need to be added or rebuilt for this theme.
+
+Build with the distribution's `python3-sphinx`. After installing the HTML
+into the package staging directory, use `dh_sphinxdoc` (or `dh --with
+sphinxdoc`) to replace Sphinx's standard JavaScript files with system
+symlinks. Include `${sphinxdoc:Depends}` in the package dependencies and
+`${sphinxdoc:Built-Using}` where required for generated assets. The custom
+`zoitechat-docs.js` remains a small, readable project source file.
+
+A built-in theme is still selectable with `-D html_theme=classic` if a
+packager needs a different layout. The old RST content has existing build
+diagnostics; changing the theme does not suppress or alter them.
+
+Shared website chrome is in `_static/css/zoitechat-site.css`, copied from the main site. Keep that readable stylesheet in sync when changing the shared header, navigation, typography, or colours.

 ZoiteChat ChangeLog
 =================
 
+2.19.1 (2026-09-15)
+-------------------
+
+- Fixed ``/msg`` messages showing twice on servers using IRCv3 ``echo-message``.
+- Fixed escaping a leading command slash so ``//text`` sends ``/text`` as normal chat.
+- Fixed automatic away clearing when sending messages on servers using ``echo-message``.
+- Fixed other users' away status not updating until rejoining a channel when ``away-notify`` updates are missed.
+- Fixed private messages and ``/me`` actions being routed to the wrong window when using WeeChat's IRC relay, while preserving channel ACTION routing.
+- Fixed a Flatpak startup error caused by the D-Bus service still using the old HexChat app ID.
+- Fixed optional Windows 10 theme downloads in the Windows installer.
+- Fixed the GTK warning when switching from channel tabs to the channel tree.
+- Fixed GTK3 theme archive root detection so themes with an ``index.theme`` file are preferred correctly.
+- Fixed source-build configuration when plugin AppStream metadata installation is disabled, and corrected the minimum Meson version to 0.59.
