 * `Symbols Nerd Font Mono` is now bundled with WezTerm and is included as a default fallback font. This means that you may use any of the glyphs available in the [Nerd Fonts](https://github.com/ryanoasis/nerd-fonts) collection with any font without patching fonts and without explicitly adding that font to your fallback list. Pomicons have an unclear license for distribution and are excluded from this bundled font, however, you may manually install the font with those icons from the Nerd Font site itself and it will take precedence over the bundled font.  This font replaces the older `PowerlineExtraSymbols` font.  [#1521](https://github.com/wez/wezterm/issues/1521).
 * [wezterm.nerdfonts](config/lua/wezterm/nerdfonts.md) as a convenient way to resolve Nerd Fonts glyphs by name in your config file
 * [ShowLauncherArgs](config/lua/keyassignment/ShowLauncherArgs.md) key assignment to show the launcher scoped to certain items, or to launch it directly in fuzzy matching mode
