* [PaneInformation.domain_name](config/lua/PaneInformation.md) and [pane:get_domain_name()](config/lua/pane/get_domain_name.md) which return the name of the domain with which a pane is associated. [#1881](https://github.com/wez/wezterm/issues/1881)
* You may now use `CTRL-n` and `CTRL-p` (in addition to the up/down arrow and vi motion keys) to change the selected row in the Launcher. Thanks to [@Junnplus](https://github.com/Junnplus)! [#1880](https://github.com/wez/wezterm/pull/1880)
* Attaching multiplexer domains now attaches the first window as a tab in the active window, rather than opening a new window. [#1874](https://github.com/wez/wezterm/issues/1874)
* Specifying a domain name in a [SpawnCommand](config/lua/SpawnCommand.md) will cause that domain to be attached if it is in the detached state. This is useful when combined with [SwitchToWorkspace](config/lua/keyassignment/SwitchToWorkspace.md).
* Debian packages now register wezterm as an alternative for `x-terminal-emulator`. Thanks to [@xpufx](https://github.com/xpufx)! [#1883](https://github.com/wez/wezterm/pull/1883)
* Scrollbar stopped working after a lot of output scrolled outside of the scrollback limit. Thanks to [@davidrios](https://github.com/davidrios)! [#1866](https://github.com/wez/wezterm/pull/1866)
*`wezterm start --position x,y`, `wezterm start --position displayname:30%,30%` option to control starting window position on all systems except for Wayland. See `wezterm start --help` for more info. [#1794](https://github.com/wez/wezterm/issues/1794)
* Default key assignments are `mapped:` again. A new [key_map_preference](config/lua/config/key_map_preference.md) option allows the defaults to use `"Mapped"` or `"Physical"`.
* Disabled ligatures for `"Monaco"` and `"Menlo"` fonts, as those have `"fi"` ligatures that match even for words such as `find`. [#1786](https://github.com/wez/wezterm/issues/1786) [#1736](https://github.com/wez/wezterm/issues/1736)
* Removed the `send_composed_key_when_alt_is_pressed` option. When processing generic `ALT` (eg: that has neither left nor right), if either `send_composed_key_when_left_alt_is_pressed` or `send_composed_key_when_right_alt_is_pressed` is true, then the composed form of the key event will be generated.
* You may now [specify a scaling factor per fallback font](config/lua/wezterm/font_with_fallback.md#manual-fallback-scaling), which is useful when your preferred CJK font renders smaller than your Roman primary font, for example.
* Wayland: touchpad scroll is now more responsive/precise. Thanks to [@davidrios](https://github.com/davidrios)! [#1800](https://github.com/wez/wezterm/pull/1800) [#1840](https://github.com/wez/wezterm/pull/1840)
* Kitty image protocol: now also supports shared memory data transmission. Thanks to [@tantei3](https://github.com/tantei3)! [#1810](https://github.com/wez/wezterm/pull/1810)
*`window_decorations = "RESIZE"` on Windows prevented minimize/maximize and aerosnap, double click to maximize, and had an ugly top border. Many thanks to [@davidrios](https://github.com/davidrios)! [#1674](https://github.com/wez/wezterm/issues/1674) [#1675](https://github.com/wez/wezterm/pull/1675) [#1771](https://github.com/wez/wezterm/pull/1771)
* On Windows, explorer shortcut icons with the maximized setting would fall out of maximized state on startup. Thanks to [@davidrios](https://github.com/davidrios)! [#1502](https://github.com/wez/wezterm/issues/1502)
*`LANG` environment variable was not always set on macOS, leading to mojibake when entering CJK. [#1761](https://github.com/wez/wezterm/issues/1761) [#1765](https://github.com/wez/wezterm/issues/1765)
* Fonts with only non-unicode names (eg: only using a Chinese multibyte string encoding) were treated as having names like `?????` and were not accessible. [#1761](https://github.com/wez/wezterm/issues/1761)
* On macOS, the font size could incorrectly double or halve after waking from sleep or moving the window to/from an external monitor. [#1566](https://github.com/wez/wezterm/issues/1566) [#1745](https://github.com/wez/wezterm/issues/1745)
* On Windows, touchpad scrolling was janky. Many thanks to [@davidrios](https://github.coim/davidrios)! [#1773](https://github.com/wez/wezterm/pull/1773) [#1725](https://github.com/wez/wezterm/pull/1725) [#949](https://github.com/wez/wezterm/pull/949)
* X11: workaround i3-gaps not sending initial CONFIGURE_NOTIFY or FOCUS events, leading to weird initial window size and broken focus status. [#1710](https://github.com/wez/wezterm/issues/1710) [#1757](https://github.com/wez/wezterm/issues/1757)
*`CloseCurrentPane{confirm=false}` would leave behind a phantom tab/pane when used with the multiplexer. [#1277](https://github.com/wez/wezterm/issues/1277)
* Scrollbar thumb could jump around/move out of bounds. Thanks to [@davidrios](https://github.com/davidrios)! [#1525](https://github.com/wez/wezterm/issues/1525)
* Multiplexer render update laggy, especially when using multiple windows. [#1814](https://github.com/wez/wezterm/issues/1814) [#1841](https://github.com/wez/wezterm/issues/1841)
* [window:composition_status()](config/lua/window/composition_status.md) and [window:leader_is_active()](config/lua/window/leader_is_active.md) methods that can help populate [window:set_right_status()](config/lua/window/set_right_status.md) [#686](https://github.com/wez/wezterm/issues/686)
* Support for SGR-Pixels mouse reporting. Thanks to [Autumn Lamonte](https://gitlab.com/autumnmeowmeow)! [#1457](https://github.com/wez/wezterm/issues/1457)
* Windows: wezterm may now use [win32-input-mode](https://github.com/microsoft/terminal/blob/main/doc/specs/%234999%20-%20Improved%20keyboard%20handling%20in%20Conpty.md) to send high-fidelity keyboard input to ConPTY. This means that win32 console applications, such as [FAR Manager](https://github.com/FarGroup/FarManager) that use the low level `INPUT_RECORD` API will now receive key-up events as well as events for modifier-only key presses. Use `allow_win32_input_mode=true` to enable this. [#318](https://github.com/wez/wezterm/issues/318) [#1509](https://github.com/wez/wezterm/issues/1509) [#1510](https://github.com/wez/wezterm/issues/1510)
* Windows: [default_domain](config/lua/config/default_domain.md), [wsl_domains](config/lua/config/wsl_domains.md) options and [wezterm.default_wsl_domains()](config/lua/wezterm/default_wsl_domains.md) provide more flexibility for WSL users.
*`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).
* [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
* Workspaces. Follow work in progress on [#1531](https://github.com/wez/wezterm/issues/1531) and [#1322](https://github.com/wez/wezterm/discussions/1322)! [window:active_workspace()](config/lua/window/active_workspace.md), [default_workspace](config/lua/config/default_workspace.md), [SwitchWorkspaceRelative](config/lua/keyassignment/SwitchWorkspaceRelative.md), [SwitchToWorkspace](config/lua/keyassignment/SwitchToWorkspace.md)
*`wezterm cli send-text "hello"` allows sending text, as though pasted, to a pane. See `wezterm cli send-text --help` for more information. [#888](https://github.com/wez/wezterm/issues/888)
*`local_echo_threshold_ms` option to adjust the predictive local echo timing for [SshDomain](config/lua/SshDomain.md), [TlsDomainClient](config/lua/TlsDomainClient.md) and [unix domains](multiplexing.md). Thanks to [@qperret](https://github.com/qperret)! [#1518](https://github.com/wez/wezterm/pull/1518)
* It is now possible to set `selection_fg` and `selection_bg` to be fully or partially transparent. [Read more](config/appearance.md). [#1615](https://github.com/wez/wezterm/issues/1615)
* Experimental (and incomplete!) support for Bidi/RTL can be enabled through the config. [Follow along in the tracking issue](https://github.com/wez/wezterm/issues/784)
* Primary selection is now supported on Wayland systems that implement [primary-selection-unstable-v1](https://wayland.app/protocols/primary-selection-unstable-v1) or the older Gtk primary selection protocol. Thanks to [@lunaryorn](https://github.com/lunaryorn)! [#1423](https://github.com/wez/wezterm/issues/1423)
* [pane:has_unseen_output()](config/lua/pane/has_unseen_output.md) and [PaneInformation.has_unseen_output](config/lua/PaneInformation.md) allow coloring or marking up tabs based on unseen output. [#796](https://github.com/wez/wezterm/discussions/796)
*`wezterm cli`, when run outside of a wezterm pane, now prefers to connect to the main GUI instance rather than background mux server. Use `wezterm cli --prefer-mux` to ignore the GUI instance and talk only to the mux server. See `wezterm cli --help` for additional information.
* [ScrollByPage](config/lua/keyassignment/ScrollByPage.md) now accepts fractional numbers like `0.5` to scroll by half a page at time. Thanks to [@hahuang65](https://github.com/hahuang65)! [#1534](https://github.com/wez/wezterm/pull/1534)
* [canonicalize_pasted_newlines](config/lua/config/canonicalize_pasted_newlines.md) default has changed to be more compatible for `nano` users, and now provides more control over the text format that is pasted. [#1575](https://github.com/wez/wezterm/issues/1575)
* Blinking text is now eased rather than binary-blinked. See [text_blink_ease_in](config/lua/config/text_blink_ease_in.md) and [text_blink_ease_out](config/lua/config/text_blink_ease_out.md), [text_blink_rapid_ease_in](config/lua/config/text_blink_rapid_ease_in.md) and [text_blink_rapid_ease_out](config/lua/config/text_blink_rapid_ease_out.md) for more information.
* Blinking text cursor is now eased rather than binary-blinked. See [cursor_blink_ease_in](config/lua/config/cursor_blink_ease_in.md) and [cursor_blink_ease_out](config/lua/config/cursor_blink_ease_out.md).
* IME and dead key composition state now shows inline in the terminal using the terminal font (All platforms, except Wayland where we only support dead key composition)
* Cursor location on the primary screen wasn't updated correctly if the window was resized while the alternate screen was active [#1512](https://github.com/wez/wezterm/issues/1512)
* Windows: latency issue with AltSnap and other window-managery things [#1013](https://github.com/wez/wezterm/issues/1013) [#1398](https://github.com/wez/wezterm/issues/1398) [#1075](https://github.com/wez/wezterm/issues/1075) [#1099](https://github.com/wez/wezterm/issues/1099)
* [ScrollToPrompt](config/lua/keyassignment/ScrollToPrompt.md) could get confused when there were multiple prompts on the same line [#1121](https://github.com/wez/wezterm/issues/1121)
* Set the sticky bit on socket and pid files created in `XDG_RUNTIME_DIR` to avoid removal by tmpwatch [#1601](https://github.com/wez/wezterm/issues/1601)
* Shaping combining sequences like `e U+20d7` could "lose" the vector symbol if the font produced an entry with no `x_advance`. [#1617](https://github.com/wez/wezterm/issues/1617)
* Setting the cursor color via escape sequences now take precedence over `force_reverse_video_cursor`. [#1625](https://github.com/wez/wezterm/issues/1625)
* Fixed Detection of DECSDM support via DECRQM/DECRPM, Correct sixel image placement when DECSDM is set and VT340 default sixel colors. Thanks to [Autumn](https://github.com/autumnmeowmeow)! [#1577](https://github.com/wez/wezterm/pull/1577)
* Fixed lingering hover state in titlebar when the mouse pointer left the window. Thanks to [@davidrios](https://github.com/davidrios)! [#1434](https://github.com/wez/wezterm/issues/1434)
* We now respect the difference between `Italic` and `Oblique` font styles when matching fonts. You may explicitly specify `style="Oblique"` rather than using `italic=true` for fonts that offer both italic and oblique variants. [#1646](https://github.com/wez/wezterm/issues/1646)
* Fancy Tab Bars are now the default. The default tab bar colors have changed to accommodate the new more native look. You can turn them off by setting [use_fancy_tab_bar = false](config/lua/config/use_fancy_tab_bar.md).
* Support for the [Kitty Image Protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/) is now enabled by default. Most of the protocol is supported; animation support is not yet implemented. Try the amazing [notcurses](https://notcurses.com/) if you want to see what modern terminal graphics can do! [#986](https://github.com/wez/wezterm/issues/986)
* unix domains now support an optional `proxy_command` to use in place of a direct unix socket connection. [Read more about multiplexing unix domains](multiplexing.html#unix-domains)
* [mux-is-process-stateful](config/lua/mux-events/mux-is-process-stateful.md) event for finer control over prompting when closing panes. [#1412](https://github.com/wez/wezterm/issues/1412)
* [harfbuzz_features](config/font-shaping.md), [freetype_load_target](config/lua/config/freetype_load_target.md), [freetype_render_target](config/lua/config/freetype_render_target.md) and [freetype_load_flags](config/lua/config/freetype_load_flags.md) can now be overridden on a per-font basis as described in [wezterm.font](config/lua/wezterm/font.md) and [wezterm.font_with_fallback](config/lua/wezterm/font_with_fallback.md).
* [wezterm.open_wth](config/lua/wezterm/open_with.md) function for opening URLs/documents with the default or a specific application [#1362](https://github.com/wez/wezterm/issues/1362)
* [pane:get_foreground_process_name()](config/lua/pane/get_foreground_process_name.md) method, [PaneInformation](config/lua/PaneInformation.md) now has `foreground_process_name` and `current_working_dir` fields, and [pane:get_current_working_dir](config/lua/pane/get_current_working_dir.md) is now supported on Windows for local processes, even without using OSC 7. [#1421](https://github.com/wez/wezterm/discussions/1421) [#915](https://github.com/wez/wezterm/issues/915) [#876](https://github.com/wez/wezterm/issues/876)
* [ActivatePaneDirection](config/lua/keyassignment/ActivatePaneDirection.md) now also supports `"Next"` and `"Prev"` to cycle through panes [#976](https://github.com/wez/wezterm/issues/976)
* [pane:get_logical_lines_as_text](config/lua/pane/get_logical_lines_as_text.md) to retrieve unwrapped logical lines from a pane [#1468](https://github.com/wez/wezterm/issues/1468)
* [wezterm.get_builtin_color_schemes()](config/lua/wezterm/get_builtin_color_schemes.md) function to eg: pick a random scheme per window, or otherwise reason about schemes. See [the docs](config/lua/wezterm/get_builtin_color_schemes.md) for examples!
* The default `CompleteSelectionOrOpenLinkAtMouseCursor` left button release assignment now also accepts SHIFT being held in order to make SHIFT-click `ExtendSelectionToMouseCursor` feel more ergonomic if the mouse button is released before the SHIFT key. [#1204](https://github.com/wez/wezterm/issues/1204)
* Unicode BIDI and other zero-width graphemes are now filtered out from the terminal model. It's not ideal in the sense that that information is essentially lost when copying to the clipboard, but it makes the presentation correct. [#1422](https://github.com/wez/wezterm/issues/1422)
* Line/Bar cursors in [force_reverse_video_cursor](config/lua/config/force_reverse_video_cursor.md) mode now use the text foreground color rather than the cursor border color. [#1076](https://github.com/wez/wezterm/issues/1076)
* You can now pass [SendKey](config/lua/keyassignment/SendKey.md) to [wezterm.action](config/lua/wezterm/action.md) and make your `keys` config look more consistent
* DECSTR (terminal soft reset) now turns off DECLRMM (left and right margin mode). Thanks to [@ninjalj](https://github.com/ninjalj)! [#1376](https://github.com/wez/wezterm/pull/1376)
* Improved conformance of CUP, HVP, SLRM, STBM escape sequences by support empty first parameter. Thanks to [@ninjalj](https://github.com/ninjalj)! [#1377](https://github.com/wez/wezterm/pull/1377)
* tab bar didn't correctly handle double-wide cells and could truncate at edges when using `format-tab-title` [#1371](https://github.com/wez/wezterm/issues/1371)
* Pixel geometry configured on the PTY in new windows could be incorrect on HiDPI displays until the window was resized [#1387](https://github.com/wez/wezterm/issues/1387)
* Image attachment geometry for imgcat and sixels could stretch the image across the rounded up number of cells that contained the image. [#1300](https://github.com/wez/wezterm/issues/1300), [#1270](https://github.com/wez/wezterm/issues/1270)
* Clicking when unfocused could lead to unwanted text selection [#1140](https://github.com/wez/wezterm/issues/1140) [#1310](https://github.com/wez/wezterm/issues/1310)
* Changing font scaling on Windows no longer causes the initial terminal rows/cols to be under-sized [#1381](https://github.com/wez/wezterm/issues/1381)
* New version update notifications are now more coordinated between multiple wezterm GUI instances, and update related configuration now respects configuration reloading. [#1402](https://github.com/wez/wezterm/issues/1402)
* Closing a window will no longer recursively terminate contained multiplexer client panes; the window will instead be restored when you next connect to that multiplexer server. Killing/closing individual tabs/panes *will* kill the panes; this change only affects closing the window. [#848](https://github.com/wez/wezterm/issues/848) [#917](https://github.com/wez/wezterm/issues/917) [#1224](https://github.com/wez/wezterm/issues/1224)
*`wezterm ssh` no longer tries to use `default_prog` or `default_cwd` when spawning additional panes on the remote host [#1456](https://github.com/wez/wezterm/issues/1456)
* Windows: `wezterm <something>` would fail silently when spawning `wezterm-gui` under the covers. Regression introduced by [#1278](https://github.com/wez/wezterm/issues/1278). Workaround is to directly spawn `wezterm-gui`.
* Windows: the PTY handles were ignored in favor of the redirected stdio handles of the parent of the wezterm mux process [#1358](https://github.com/wez/wezterm/issues/1358)
* Windows: Failure to spawn `wezterm` when launching an ssh mux domain session no longer waits forever
* X11 now supports IME. It currently defaults to disabled, but you can set `use_ime = true` in your config to enable it (you need to restart wezterm for this to take effect). Many thanks to [@H-M-H](https://github.com/H-M-H) for bringing xcb-imdkit to Rust and implementing this in wezterm! [#250](https://github.com/wez/wezterm/issues/250) [#1043](https://github.com/wez/wezterm/pull/1043)
* it is now possible to define colors in the range 16-255 in `colors` and color scheme definitions. Thanks to [@potamides](https://github.com/potamides)! [#841](https://github.com/wez/wezterm/issues/841) [#1056](https://github.com/wez/wezterm/pull/1056)
* Added [SendKey](config/lua/keyassignment/SendKey.md) key assignment action that makes it more convenient to rebind the key input that is sent to a pane.
* Added [Multiple](config/lua/keyassignment/Multiple.md) key assignment action for combining multuple actions in a single press.
* Added [use_resize_increments](config/lua/config/use_resize_increments.md) option to tell X11, Wayland, macOS window resizing to prefers to step in increments of the cell size
* [visual_bell](config/lua/config/visual_bell.md) and [audible_bell](config/lua/config/audible_bell.md) configuration options, as well as a [bell](config/lua/window-events/bell.md) event allows you to trigger lua code when the bell is rung. [#3](https://github.com/wez/wezterm/issues/3)
* [wezterm.action_callback](config/lua/wezterm/action_callback.md) function to make it easier to use custom events. Thanks to [@bew](https://github.com/bew)! [#1151](https://github.com/wez/wezterm/pull/1151)
*`wezterm connect` now also supports the `--class` parameter to override the window class
* [window_padding](config/lua/config/window_padding.md) now accepts values such as `"1cell"` or `"30%"` to compute values based on font or window metrics.
* BSDish systems now support [toast notifications](https://github.com/wez/wezterm/issues/489)
* [mux_env_remove](config/lua/config/mux_env_remove.md) setting to control which environment variables should be cleared prior to spawning processes in the multiplexer server [#1225](https://github.com/wez/wezterm/issues/1225)
* [canonicalize_pasted_newlines](config/lua/config/canonicalize_pasted_newlines.md) option to help Windows users manage newlines in pastes [#1213](https://github.com/wez/wezterm/issues/1213)
* [unicode_version](config/lua/config/unicode_version.md) option and corresponding OSC escape sequences that affects how the width of certain unicode sequences are interpreted.
* macOS: binaries produced by wezterm's CI are now codesigned, which resolves some spurious permission dialogs that affected some users [#482](https://github.com/wez/wezterm/issues/482)
* new default key assignments: CTRL+PageUp and CTRL+Tab activate next tab, CTRL+PageDown and CTRL+SHIFT+Tab activate previous tab. ALT+{1..8} directly select the first through 8th tabs. Thanks to [@friederbluemle](https://github.com/friederbluemle)! [#1132](https://github.com/wez/wezterm/pull/1132)
* X11: we now allow matching visuals with >= 8 bits per rgb value. Previously, we only matched exactly 8 bits. This improve compatibility with systems that have the COMPOSITE extension disabled. Thanks to [@shizeeg](https://github.com/shizeeg)! [#1083](https://github.com/wez/wezterm/pull/1083)
* Windows: `wezterm-gui.exe` now only grabs the parent process' console handle when spawned from `wezterm.exe`, which prevents some frustrating interactions when launching `wezterm-gui.exe` via `start` in cmd/powershell. [#1278](https://github.com/wez/wezterm/issues/1278)
* AppImage: take care to remove APPIMAGE related environment when spawning child processes. Thanks to [@srevinsaju](https://github.com/srevinsaju)! [#1338](https://github.com/wez/wezterm/pull/1338)
* bundled harfbuzz updated to version 3.0.0, bundled freetype updated to 2.11

* multi-click-streaks are now interrupted by the cursor moving to a different cell. Thanks to [@unrelentingtech](https://github.com/unrelentingtech)! [#1126](https://github.com/wez/wezterm/issues/1126)
*`.deb` packages now `Provides: x-terminal-emulator`. [#1139](https://github.com/wez/wezterm/issues/1139)
* [use_cap_height_to_scale_fallback_fonts](config/lua/config/use_cap_height_to_scale_fallback_fonts.md) now computes *cap-height* based on the rasterized glyph bitmap which means that the data is accurate in more cases, including for bitmap fonts. Scaling is now also applied across varying text styles; previously it only applied to a font within an `wezterm.font_with_fallback` font list.
* Can now match fontconfig aliases, such as `monospace`, on systems that use fontconfig. Thanks to [@unrelentingtech](https://github.com/unrelentingtech)! [#1149](https://github.com/wez/wezterm/issues/1149)
* Powerline semicircle glyphs now look much better. Thanks to [@bew](https://github.com/bew) and [@sdrik](https://github.com/sdrik)! [#1311](https://github.com/wez/wezterm/issues/1311)
* Splits now look better, especially when using escape sequences to change the default background color [#1256](https://github.com/wez/wezterm/issues/1256)
*`wezterm cli spawn` would use the initial terminal size for a new tab, rather than using the current tab size [#920](https://github.com/wez/wezterm/issues/920)
*`text_background_opacity` opacity was not respected
* spawning commands via the mux didn't respect the `PATH` configured in `set_environment_variables`. [#1029](https://github.com/wez/wezterm/issues/1029)
* cursor could have a transparent "hole" through the window with certain cursor styles
* Consolas font + random input could cause a divide-by-zero when computing glyph metrics [#1042](https://github.com/wez/wezterm/issues/1042)
* Emoji fallback was too strict in respecting VS15/VS16 presentation selection, adjust the fallback to allow showing Emoji/Text presentation if Text/Emoji was requested but not found.
* X11: laggy input after selecting text. [#1027](https://github.com/wez/wezterm/issues/1027)

* incorrect spacing for IDEOGRAPHIC SPACE. [#1161](https://github.com/wez/wezterm/issues/1161)
* italic fonts weren't always recognized as being italic, resulting in italic variants being used instead of the non-italic variants in some cases! [#1162](https://github.com/wez/wezterm/issues/1162)
* Ask freetype for cell metrics in bitmap-only fonts, rather than simply taking the bitmap width. [#1165](https://github.com/wez/wezterm/issues/1165)

* multiplexer: wrong `WEZTERM_UNIX_SOCKET` environment passed to children when using unix domain sockets and `connect_automatically=true` [#1222](https://github.com/wez/wezterm/issues/1222)
* multiplexer: spawning remote tabs didn't correctly record local tab mapping, resulting in phantom additional tabs showing in the client. [#1222](https://github.com/wez/wezterm/issues/1222)
* Reloading config now loads newly defined multiplexer domains, however, existing domains are not updated. [#1279](https://github.com/wez/wezterm/issues/1279)

* New: Added support for [Synchronized Rendering](https://gist.github.com/christianparpart/d8a62cc1ab659194337d73e399004036) [#882](https://github.com/wez/wezterm/issues/882)
* New: wezterm now draws its own pixel-perfect versions of more block drawing glyphs. See [custom_block_glyphs](config/lua/config/custom_block_glyphs.md) for more details. [#584](https://github.com/wez/wezterm/issues/584)
* Updated bundled `Noto Color Emoji` font to version 2.028 featuring a [design update](https://blog.google/products/android/emoji-day-redesign-easier-sharing/). Thanks to [@4cm4k1](https://github.com/4cm4k1)! [#1003](https://github.com/wez/wezterm/pull/1003)

* Improved: wezterm now respects default emoji presentation and explicit emoji variation selectors (VS15 and VS16) so that glyphs that have both textual (usually monochrome, single cell width) and emoji (color, double width) presentations can be more faithfully rendered. [#997](https://github.com/wez/wezterm/issues/997)
* Fixed: red and blue subpixel channels were swapped, leading to excessively blurry text when using `freetype_load_flags="HorizontalLcd"`. [#639](https://github.com/wez/wezterm/issues/639)
* New: [wezterm.font](config/lua/wezterm/font.md) and [wezterm.font_with_fallback](config/lua/wezterm/font_with_fallback.md) *attributes* parameter now allows matching more granular font weights and font stretch. e.g.: `wezterm.font('Iosevka Term', {stretch="Expanded", weight="Regular"})`, as fallback can specify weight/stretch/style for each individual font in the fallback.
* New [window:toast_notification](config/lua/window/toast_notification.md) method for showing desktop notifications. [#619](https://github.com/wez/wezterm/issues/619)
* Improved: [font_rules](config/lua/config/font_rules.md) behavior to always append reasonable default `font_rules` to those that you may have specified in your config. `font_rules` now also include defaults for half-bright text styles.
* Improved: added [use_cap_height_to_scale_fallback_fonts](config/lua/config/use_cap_height_to_scale_fallback_fonts.md) option to scale secondary fonts according to relative their *cap-height* metric to improve size consistency. This partially applies to some symbol/emoji fonts, but is dependent upon the font having reliable metrics.
* Fixed: [Hide](config/lua/keyassignment/Hide.md) had no effect on macOS when the titlebar was disabled [#679](https://github.com/wez/wezterm/issues/679)
* Fixed: key and mouse assignments set via [window:set_config_overrides](config/lua/window/set_config_overrides.md) were not respected. [#656](https://github.com/wez/wezterm/issues/656)
* New: [format-tab-title](config/lua/window-events/format-tab-title.md) hook for customizing the text in tab titles. [#647](https://github.com/wez/wezterm/issues/647)
* Removed: active and inactive [tab_bar_style](config/lua/config/tab_bar_style.md) config values; use the new [format-tab-title](config/lua/window-events/format-tab-title.md) event instead
* New: [force_reverse_video_cursor](config/lua/config/force_reverse_video_cursor.md) setting to override the cursor color scheme settings. [#706](https://github.com/wez/wezterm/issues/706)

* New: [wezterm.pad_left](config/lua/wezterm/pad_left.md), [wwezterm.pad_right](config/lua/wezterm/pad_right.md), [wezterm.truncate_left](config/lua/wezterm/truncate_left.md) and [wezterm.truncate_right](config/lua/wezterm/truncate_right.md) function for truncating/padding a string based on its displayed width
* Updated bundled `Noto Color Emoji` font to version 2.020 with unicode 13.1 support. Thanks to [@4cm4k1](https://github.com/4cm4k1)! [#742](https://github.com/wez/wezterm/pull/742)
* Fixed: wezterm now sets argv0 to `-$SHELL` to invoke a login shell, rather than running `$SHELL -l`. [#753](https://github.com/wez/wezterm/issues/753)
* Fixed: the pixel size reported by the pty to the kernel wasn't adjusted for font metrics/dpi until the config was reloaded or window resized. [#563](https://github.com/wez/wezterm/issues/563)
* Fixed: Windows: `window_background_opacity` was only taking effect when `window_decorations="NONE"` [#553](https://github.com/wez/wezterm/issues/553)
* Fixed: font fallback on macOS returns unresolvable `.AppleSymbolsFB` rather than `Apple Symbols`, leading to slowdowns when rendering symbols [#506](https://github.com/wez/wezterm/issues/506)
* Fixed: laggy repaints for large windows particularly on Windows, but applicable to all systems. Tuned and triple-buffered vertex buffer updates. [#546](https://github.com/wez/wezterm/issues/546)
* Changed: [allow_square_glyphs_to_overflow_width](config/lua/config/allow_square_glyphs_to_overflow_width.md) now defaults to `WhenFollowedBySpace` and applies to more symbol glyphs. [#565](https://github.com/wez/wezterm/issues/565)
* New: added [skip_close_confirmation_for_processes_named](config/lua/config/skip_close_confirmation_for_processes_named.md) option which specifies a list of processes for which it is considered safe to allow closing a pane/tab/window without a prompt. [#562](https://github.com/wez/wezterm/issues/562)
* Fixed: triggering the search overlay again while the search overlay is active no longer closes the underlying pane [#572](https://github.com/wez/wezterm/issues/572)
* Fixed: X10 mouse coordinate reporting encoding could produce invalid outputs for large windows. Capped coordinate values to the maximum value that is representable in UTF-8 encoding
* Fixed: implicit hyperlink rules, word and line selection now operate on logical lines which means that they deal with wrapped lines outside of the viewport. [#408](https://github.com/wez/wezterm/issues/408)
* New: `wezterm ssh` now supports reading `~/.ssh/config` and overriding options via the command line. `IdentityFile` and `ProxyCommand` are the two main new supported options. Read more about it in [ssh](ssh.md).
* Fixed: ssh support will now try all available identities from the SSH agent rather than just the first.
* New: splitting panes in `wezterm ssh` now works like spawning new tabs: the new program is started on the remote host with no additional authentication required.
* Fixed: Multiplexer sessions would fail to bootstrap via ssh because the bootstrap process exited too soon. [#507](https://github.com/wez/wezterm/issues/507)
* Fixed: Windows: we now compile libssh2 against openssl on all platforms to improve overall key and crypto algorithm support
* Fixed: spawning a new tab via the launcher menu failed because it used the pretty printed multiplexer domain label rather than the multiplexer domain name.
* New: added [ActivateLastTab](config/lua/keyassignment/ActivateLastTab.md) key assignment for jumping back to a previously active tab. Thanks to [@alexgartrell](https://github.com/alexgartrell) [#610](https://github.com/wez/wezterm/pull/610)
* Fixed: avoid showing an error dialog for synthesized `font_rules` when the configuration specifies a font that doesn't have bold/italic variants. [#617](https://github.com/wez/wezterm/issues/617)
* New: mouse cursor hides when keyboard input is sent to a pane, and shows again when the mouse is moved. [#618](https://github.com/wez/wezterm/issues/618)
* Fixed: macOS: CTRL-Tab key combination was not recognized. [#630](https://github.com/wez/wezterm/issues/630)
* Fixed: wezterm-mux-server will now continue running even after all tabs/panes have been closed. [#631](https://github.com/wez/wezterm/issues/631)
* Fixed: macOS: wezterm-gui could linger in the background until the mouse moves after all tabs/panes have closed
* Fixed: when using [line_height](config/lua/config/line_height.md), wezterm now vertically centers the cell rather than padding only the top [#582](https://github.com/wez/wezterm/issues/582)
* Fixed: macOS: in US layouts, `SUPER+SHIFT+[` was incorrectly recognized as `SUPER+SHIFT+{` instead of `SUPER+{` [#601](https://github.com/wez/wezterm/issues/601)
* New: [tab_bar_style](config/lua/config/tab_bar_style.md) allows customizing the appearance of the rest of tha tab bar.
* New: animated gif and png images displayed via `wezterm imgcat` (the iTerm2 image protocol), or attached to the window background via [window_background_image](config/appearance.html#window-background-image) will now animate while the window has focus.
* New: OSC 777 and OSC 9 escapes now generate Toast Notifications. `printf "\e]777;notify;%s;%s\e\\" "title" "body"` and `printf "\e]9;%s\e\\" "hello there"`. These don't currently pass through multiplexer connections. [#489](https://github.com/wez/wezterm/issues/489).
* New: [exit_behavior](config/lua/config/exit_behavior.md) config option to keep panes open after the program has completed. [#499](https://github.com/wez/wezterm/issues/499)
* New: added `--config name=value` options to `wezterm`, `wezterm-gui` and `wezterm-mux-server`. The `--front-end`, `--font-locator`, `--font-rasterizer` and `--font-shaper` CLI options have been removed in favor of this new mechanism.
* New: [window:set_config_overrides](config/lua/window/set_config_overrides.md) method that can be used to override GUI related configuration options on a per-window basis. Click through to see examples of dynamically toggling ligatures and window opacity. [#469](https://github.com/wez/wezterm/issues/469) [#329](https://github.com/wez/wezterm/issues/329)
* New: introduced [custom_block_glyphs](config/lua/config/custom_block_glyphs.md) option to ensure that block glyphs don't have gaps. [#433](https://github.com/wez/wezterm/issues/433)
* New: holding SUPER+Drag (or CTRL+SHIFT+Drag) will drag the wezterm window. Use [StartWindowDrag](config/lua/keyassignment/StartWindowDrag.md) to configure your own binding.
* New: configure [window_decorations](config/lua/config/window_decorations.md) to remove the title bar and/or window border
* New: we now bundle [PowerlineExtraSymbols](https://github.com/ryanoasis/powerline-extra-symbols) as a built-in fallback font, so that you can use powerline glyphs with any font without patching the font.
* New: [window:set_right_status](config/lua/window/set_right_status.md) allows setting additional status information in the tab bar. [#500](https://github.com/wez/wezterm/issues/500)
* New: Search Mode: Added `CTRL-u` key assignment to clear the current search pattern. Thanks to [@bew](https://github.com/bew)! [#465](https://github.com/wez/wezterm/pull/465)
* Fonts: `font_antialias` and `font_hinting` are now deprecated in favor of the new [freetype_load_target](config/lua/config/freetype_load_target.md) and [freetype_load_flags](config/lua/config/freetype_load_flags.md) options. The deprecated options have no effect and will be removed in a future release. The new options provide more direct control over how freetype rasterizes text.
* Fonts: when computing default `font_rules` for bold and italic fonts, strip italic and bold components from the family name. eg: if you set `font = wezterm.font("Source Code Pro Medium")` then the ` Medium` text will be stripped from the font name used to locate bold and italic variants so that we don't report an error loading a non-sensical `Source Code Pro Medium Bold`. [#456](https://github.com/wez/wezterm/issues/456)
* Fonts: fix a regression where bright windows behind wezterm could "shine through" on the alpha channel, and adjust the tinting operation to avoid anti-aliased dark fringes [#470](https://github.com/wez/wezterm/issues/470) [#491](https://github.com/wez/wezterm/issues/491)
* Fonts: macOS: fix an issue where wezterm could hang when loading a font located via Core Text [#475](https://github.com/wez/wezterm/issues/475)

* Added `--config-file` CLI option to specify an alternate config file location. [Read more about config file resolution](config/files.md). Thanks to [@bew](https://github.com/bew)! [#459](https://github.com/wez/wezterm/pull/459)
* OSC 52 (Clipboard manipulation) now respects the difference between PRIMARY and CLIPBOARD on X11 systems.
* Fixed an issue where large pastes could result in a hang
* Closing the configuration error window no longer requires confirmation
* Fixed: an issue where the window would be redrawn on mouse move. This was most noticeable as a laggy mouse pointer when moving the mouse across a window running on the nouveau display driver on X11 and Wayland systems
* Fixed: an issue where closing a pane would immediately `SIGKILL` the associated process, rather than sending `SIGHUP`. Thanks to [@bew](https://github.com/bew)!
* Fixed: line-based mouse selection (default: triple click) now extends forwards to include wrapped lines. [#466](https://github.com/wez/wezterm/issues/466)
* Fixed: the [RIS](https://vt100.net/docs/vt510-rm/RIS) escape wasn't clearing the scrollback. [#511](https://github.com/wez/wezterm/issues/511)
* Wayland: the raw key modifiers are now correctly propagated so that they activate when used with key assignments using the `key = "raw:123"` binding syntax.
* Wayland: fixed window decoration and full screen handling [#224](https://github.com/wez/wezterm/issues/224)
* Wayland: fixed an issue where key repeat processing could "run away" and hang the application

* Windows: Fixed [ToggleFullScreen](config/lua/keyassignment/ToggleFullScreen.md) so that it once again toggles between full screen and normal placement. [#177](https://github.com/wez/wezterm/issues/177)
* Windows: fix the unexpected default behavior of Ctrl-Alt being converted to AltGr for layouts supporting this key, the previous behavior is still possible by enabling the option [`treat_left_ctrlalt_as_altgr`](config/lua/config/treat_left_ctrlalt_as_altgr.md) (to solve [#392](https://github.com/wez/wezterm/issues/392)). Thanks to [@bew](https://github.com/bew)! [#512](https://github.com/wez/wezterm/pull/512)
* Windows: fixed "Open WezTerm Here" context menu in explorer when used on the root of a drive (eg: `C:\`). Thanks to [@flyxyz123](https://github.com/flyxyz123)! [#526](https://github.com/wez/wezterm/issues/526) [#451](https://github.com/wez/wezterm/issues/451)
* X11: we now load the XCursor themes when possible, which means that the mouse cursor is now generally a bit larger and clearer as well as conforming more with the prevailing style of the desktop environment. [#524](https://github.com/wez/wezterm/issues/524)
* Improved and optimized image processing so that watching videos via [timg - Terminal Image and Video Viewer](http://timg.sh) works better [#537](https://github.com/wez/wezterm/issues/537) [#535](https://github.com/wez/wezterm/issues/535) [#534](https://github.com/wez/wezterm/issues/534)
* Fix cursor position after using iTerm2 image protocol [#317](https://github.com/wez/wezterm/issues/317)
* Fix pixel dimensions after changing the pane size; this was mostly invisible but impacted image scaling when using sixel or iTerm2 image protocols. [#312](https://github.com/wez/wezterm/issues/312)
* Add support for OSC 133 which allows annotating output as `Output`, `Input` (that you typed) and `Prompt` (shell "chrome"). [Learn more about Semantic prompt and OSC 133](https://gitlab.freedesktop.org/Per_Bothner/specifications/blob/master/proposals/semantic-prompts.md)
* Add [`ScrollToPrompt`](config/lua/keyassignment/ScrollToPrompt.md) key assignment that scrolls the viewport to the prior/next shell prompt emitted using OSC 133 Semantic Prompt escapes. This assignment is not bound by default.
* Added `wezterm start --class CLASSNAME` option to specify the window class name under X11 and Windows, or the `app_id` under Wayland. See `wezterm start --help` for more information.
* Added shell integration for setting OSC 7 (working directory) and OSC 133 (semantic zones) for Zsh and Bash. [See Shell Integration docs](shell-integration.md).
* Added `SemanticZone` as a possible parameter for [SelectTextAtMouseCursor](config/lua/keyassignment/SelectTextAtMouseCursor.md), making it possible to conveniently select complete input or output regions.
* Improved font rendering [#320](https://github.com/wez/wezterm/issues/320) [#331](https://github.com/wez/wezterm/issues/331) [#413](https://github.com/wez/wezterm/issues/413) and changed `font_antialias = "Greyscale"` by default.
* Added `allow_square_glyphs_to_overflow_width = "WhenFollowedBySpace"` option to allow square symbol glyphs to deliberately overflow their specified cell width when the next cell is a space. Can be set to `Always` to allow overflowing regardless of the next cell being a space, or `Never` to strictly respect the cell width. The default is `Never`. [#342](https://github.com/wez/wezterm/issues/342)
* Workaround Cocoa leaking window position saved state file descriptors to child processes on macOS Big Sur, and Gnome/Mutter doing something similar under X11
* New: added `line_height` configuration option to scale the computed cell height. The default is `1.0`, resulting in using the font-specified metrics. Setting it to `1.2` will result in a 20% larger cell height.
* macOS: Fixed an issue where hovering over the split between panes could result in wezterm becoming unresponsive [#391](https://github.com/wez/wezterm/issues/391)
* Closing windows and `QuitApplication` will now prompt for confirmation before proceeding with the close/quit. Added `window_close_confirmation` to control this; valid values are `AlwaysPrompt` and `NeverPrompt`. [#280](https://github.com/wez/wezterm/issues/280)
* Tidied up logging. Previously ERROR level logging was used to make sure that informational things showed up in the stderr stream. Now we use INFO level logging for this to avoid alarming the user. You can set `WEZTERM_LOG=trace` in the environment to get more verbose logging for troubleshooting purposes.
* X11: fix an issue where keys that produce unicode characters retained SHIFT as a modifier instead of normalizing it away. [#394](https://github.com/wez/wezterm/issues/394)
* Tweaked mouse selection: we now round the x-coordinate to the nearest cell which makes it a bit more forgiving if the mouse cursor is slightly to the left of the intended cell start. [#350](https://github.com/wez/wezterm/issues/350)
* Added `selection_word_boundary` option to control double-click word selection boundaries. The default is <tt> \t\n{}\[\]()\"'\`</tt>. [#405](https://github.com/wez/wezterm/issues/405)
* Added support for Curly, Dotted and Dashed underlines. See [this documentation](faq.html#how-do-i-enable-undercurl-curly-underlines) on the escape sequences how enable undercurl support in vim and nvim. [#415](https://github.com/wez/wezterm/issues/415)
* Fixed an issue where wezterm would spawn processes with `umask 077` on unix systems, rather than the more commonly expected `umask 022`. [#416](https://github.com/wez/wezterm/issues/416)
* Fixed an issue where the mouse wheel wasn't mapped to cursor up/down when the alternate screen was active [#429](https://github.com/wez/wezterm/issues/429)
* Fixed `ToggleFullScreen` not working on macOS and X11. It still doesn't function on Windows. `native_macos_fullscreen_mode = false` uses a fast full-screen window on macOS. Set it to `true` to use the slower macOS native "Spaces" style fullscreen mode. [#177](https://github.com/wez/wezterm/issues/177)
* Windows: fix an issue where the initial window size didn't factor the correct DPI when the system-wide display scaling was not 100%. [#427](https://github.com/wez/wezterm/issues/427)
* New: `adjust_window_size_when_changing_font_size` option to control whether changing the font size adjusts the dimensions of the window (true) or adjusts the number of terminal rows/columns (false). The default is `true`. [#431](https://github.com/wez/wezterm/issues/431)
* macOS: we no longer use MetalANGLE to render the gui; it was short lived as macOS Big Sur now uses Metal in its CGL implementation. Support for using MetalANGLE is still present if the dylib is found on startup, but we no longer ship the dylib.
* Windows: when pasting text, ensure that the text has CRLF line endings unless bracketed paste is enabled. This imperfect heuristic helps to keep multi-line pastes on multiple lines when using Windows console applications and to avoid interleaved blank lines when using unix applications. [#411](https://github.com/wez/wezterm/issues/411)
* New: [ClearScrollback](config/lua/keyassignment/ClearScrollback.html) now accepts a parameter to control whether the viewport is cleared along with the scrollback. Thanks to [@dfrankland](https://github.com/dfrankland)!
* New: [default_cwd](config/lua/config/default_cwd.html) to specify an alternative current working directory. Thanks to [@dfrankland](https://github.com/dfrankland)!
* New: [CopyTo](config/lua/keyassignment/CopyTo.md) and [PasteFrom](config/lua/keyassignment/PasteFrom.md) actions. [Copy](config/lua/keyassignment/Copy.md), [Paste](config/lua/keyassignment/Paste.md) and [PastePrimarySelection](config/lua/keyassignment/PastePrimarySelection.md) are now deprecated in favor of these new options.
* X11: Mouse-based selection now copies-to and pastes-from the `PrimarySelection` by default. The [CompleteSelection](config/lua/keyassignment/CompleteSelection.md) and [CompleteSelectionOrOpenLinkAtMouseCursor](config/lua/keyassignment/CompleteSelectionOrOpenLinkAtMouseCursor.md) actions now require a parameter to specify the clipboard.
* X11: `SHIFT-CTRL-C` and `SHIFT-CTRL-V` now copy-to and paste from the `Clipboard` by default. `SHIFT-Insert` pastes from the `PrimarySelection` by default.
* New: Added a new default `CTRL-Insert` key assignment bound to `CopyTo(PrimarySelection)`
* macOS: Windows now have drop-shadows when they are opaque. These were disabled due transparency support was added. Thanks to [Rice](https://github.com/fanzeyi)! [#445](https://github.com/wez/wezterm/pull/445)
* Unix: adjust font-config patterns to also match "dual spacing" fonts such as [Iosevka Term](https://typeof.net/Iosevka/). Thanks to [Leiser](https://github.com/leiserfg)! [#446](https://github.com/wez/wezterm/pull/446)
* New: Added [alternate_buffer_wheel_scroll_speed](config/lua/config/alternate_buffer_wheel_scroll_speed.md) option to control how many cursor key presses are generated by the mouse wheel when the alternate screen is active. The new default for this is a faster-than-previous-releases 3 lines per wheel tick. [#432](https://github.com/wez/wezterm/issues/432)
* macOS: Dead Keys are now processed even when `use_ime=false`. [More details in the docs](config/keys.md#macos-left-and-right-option-key). [#410](https://github.com/wez/wezterm/issues/410).
* We now accept `rgb:XX/XX/XX` color syntax for OSC 4 and related escape
sequences; previously only `#XXXXXX` and named colors were accepted.
* We now accept OSC 104 to reset custom colors to their defaults.
* Added Tab Navigator overlay for folks that hoard tabs; it presents
an interactive UI for selecting and activating a tab from a vertically
oriented list. This is bound to `Alt-9` by default.
* Added support for DEC Origin Mode (`DECOM`) which improves cursor positioning
with some applications
* Added support for DEC AutoWrap Mode (`DECAWM`) which was previously always on.
This improves rendering for applications that explicitly disable it.
* We now show a connection status window while establishing MUX and SSH connections.
The status window is also where any interactive authentication is carried out
for eg: SSH sessions.
* Improved SSH authentication handling; we now give you a few opportunities to
authenticate and are now able to successfully authenticate with sites that
have configured 2-Factor authentication in their server side SSH configuration.
* Fixed an issue where SHIFT-Space would swallow the space key.
* Nightly builds are now available for Linux in [AppImage](https://github.com/wez/wezterm/releases/download/nightly/WezTerm-nightly.AppImage) format.
* Shift+Left Mouse button can now be used to extend the selection to the clicked location. This is particularly helpful when you want to select something that is larger than the viewport.
* Windows: a single mouse wheel tick now scrolls by the number of positions configured in the Windows system settings (default 3)
* Windows: fixed IME position when the tab bar is enabled
* Windows: removed support for WinPty, which was too difficult to obtain, configure and use.
* Configuration errors now show in a separate window on startup, or when the configuration is reloaded
* Improved reliability and performance of MUX sessions, although they still have room for further improvement
* The OSC 7 (CurrentWorkingDirectory) escape sequence is now supported; wezterm records the cwd in a tab and that will be used to set the working directory when spawning new tabs in the same domain. You will need to configure your shell to emit OSC 7 when appropriate.
The multiplexer will now raise an error if the client and server are incompatible.
* Fixed an issue where wezterm would linger for a few seconds after the last tab was closed
* Fixed an issue where wezterm wouldn't repaint the screen after a tab was closed
* Clicking the OS window close button in the titlebar now closes the window rather than the active tab
* Added `use_ime` option to optionally disable the use of the IME on macOS. You might consider enabling this if you don't like the way that the IME swallows key repeats for some keys.
* Fix an [issue](https://github.com/knsd/daemonize/pull/39) where the pidfile would leak into child processes and block restarting the mux server
* Fix an issue where the title bars of remote tabs were not picked up at domain attach time
* Fixed selection and scrollbar position for multiplexer tabs
* Added `ScrollByPage` key assignment and moved the `SHIFT+PageUp` handling up to the
gui layer so that it can be rebound.
* X11: a single mouse wheel tick now scrolls by 5 rows rather than 1
* Wayland: normalize line endings to unix line endings when pasting
* Windows: fixed handling of focus related messages, which impacted both the appearance of
the text cursor and copy and paste handling.
* When hovering over implicitly hyperlinked items, we no longer show the underline for every other URL with the same destination
* Added a `window_padding` config section to add padding to the window display
* We now respect [DECSCUSR and DECTCEM](https://github.com/wez/wezterm/issues/7) escape sequence to select between hidden, block, underline and bar cursor types, as well as blinking cursors. New configuration options have been added to control the appearance and blink rate.
* We now support an optional basic scroll bar. The scroll bar occupies the right window padding and has a configurable color. Scroll bars are not yet supported for multiplexer connections and remain disabled by default for the moment.
