* Fixed: `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)
* Fixed: `text_background_opacity` opacity was not respected
* Fixed: spawning commands via the mux didn't respect the `PATH` configured in `set_environment_variables`. [#1029](https://github.com/wez/wezterm/issues/1029)
* Fixed: cursor could have a transparent "hole" through the window with certain cursor styles
* Fixed: Consolas font + random input could cause a divide-by-zero when computing glyph metrics [#1042](https://github.com/wez/wezterm/issues/1042)
* Fixed: 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.
* New: 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)
* New: 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)
* Changed: 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)
* Fixed: macOS: `send_composed_key_when_left_alt_is_pressed` and `send_composed_key_when_right_alt_is_pressed` are now respected when `use_ime=true`. Thanks to [@jakelinnzy](https://github.com/jakelinnzy)! [#1096](https://github.com/wez/wezterm/pull/1096)

* Fixed: split separators didn't respect `tab_bar_at_bottom=true` and were rendered in the wrong place [#797](https://github.com/wez/wezterm/issues/797)
* Fixed: OSC 7 (current working directory) now works with paths that contain spaces and other special characters. Thanks to [@Arvedui](https://github.com/Arvedui)! [#799](https://github.com/wez/wezterm/pull/799)
* Changed: the homebrew tap is now a Cask that installs to the /Applications directory on macOS. Thanks to [@laggardkernel](https://github.com/laggardkernel)!
* New: bold/dim and/or italics are now synthesized for fonts when the matching font is not actually italic or doesn't match the requested weight. [#815](https://github.com/wez/wezterm/issues/815)
* Fixed: multiplexer now propagates toast notifications and color palette to client [#489](https://github.com/wez/wezterm/issues/489) [#748](https://github.com/wez/wezterm/issues/748)
* New: `CTRL+SHIFT+L` is assigned to [ShowDebugOverlay](config/lua/keyassignment/ShowDebugOverlay.md) [#641](https://github.com/wez/wezterm/issues/641)
* Improved: [skip_close_confirmation_for_processes_named](config/lua/config/skip_close_confirmation_for_processes_named.md) now includes common windows shell processes `cmd.exe`, `pwsh.exe` and `powershell.exe`. [#843](https://github.com/wez/wezterm/issues/843)
* Improved: `wezterm ls-fonts --list-system` shows all available fonts, `wezterm ls-fonts --text "hello"` explains which fonts are used for each glyph in the supplied text
* Fixed: mouse cursor is now Arrow rather than I-beam when the application in the terminal has enabled mouse reporting [#859](https://github.com/wez/wezterm/issues/859)
* Improved: DEC Special Graphics mode conformance and complete coverage of the graphics character set. Thanks to [Autumn Lamonte](https://gitlab.com/klamonte)! [#891](https://github.com/wez/wezterm/pull/891)
* Removed: `Parasio Dark` color scheme; it was a duplicate of the correctly named `Paraiso Dark` scheme. Thanks to [@adrian5](https://github.com/adrian5)! [#906](https://github.com/wez/wezterm/pull/906)
* Fixed: key repeat on Wayland now respects the system specified key repeat rate, and doesn't "stick". [#669](https://github.com/wez/wezterm/issues/669)
* Improved: implement braille characters as custom glyphs, to have perfect rendering when `custom_block_glyphs` is enabled. Thanks to [@bew](http://github.com/bew)!
* New: [window:get_appearance()](config/lua/window/get_appearance.md) to determine if the window has a dark mode appearance, and adjust color scheme to match [#806](https://github.com/wez/wezterm/issues/806)
* Fixed: if a line of text was exactly the width of the terminal it would get marked as wrappable even when followed by a newline, causing text to reflow incorrectly on resize. [#971](https://github.com/wez/wezterm/issues/971)
* Fixed: `wezterm ssh` could loop forever in the background if the connection drops and the window is closed. [#857](https://github.com/wez/wezterm/issues/857)
* New: [text_blink_rate](config/lua/config/text_blink_rate.md) and [text_blink_rate_rapid](config/lua/config/text_blink_rate_rapid.md) options to control blinking text. Thanks to [Autumn Lamonte](https://gitlab.com/klamonte)! [#904](https://github.com/wez/wezterm/pull/904)
* 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)
* Fixed: mouse reporting now correctly reports release events when multiple buttons are pressed and released at the same time. [#973](https://github.com/wez/wezterm/issues/973)
* New: CTRL-SHIFT-L shows the [debug overlay](config/lua/keyassignment/ShowDebugOverlay.md), which shows the error log and a lua repl. [#641](https://github.com/wez/wezterm/issues/641)
* Improved: wezterm now uses the Dual Source Blending feature of OpenGL to manage subpixel anti-aliasing alpha blending, resulting in improved appearance particularly when using a transparent window over the top of something with a light background. [#932](https://github.com/wez/wezterm/issues/932)
* New: [wezterm.add_to_config_reload_watch_list](config/lua/wezterm/add_to_config_reload_watch_list.md) function to aid with automatically reloading the config when you've split your config across multiple files. Thanks to [@AusCyberman](https://github.com/AusCyberman)! [#989](https://github.com/wez/wezterm/pull/989)
* 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)
* Fixed: ssh config parsing now expands `~` to your home directory for appropriate options; previously only `%d` and `${HOME}` were substituted. [#729](https://github.com/wez/wezterm/issues/729)
* New: [Quick Select Mode](quickselect.md) for a tmux-fingers/tmux-thumbs style mouse-less select and copy flow [#732](https://github.com/wez/wezterm/issues/732)
* New: [tab_bar_at_bottom](config/lua/config/tab_bar_at_bottom.md) setting to put the tab bar at the bottom of the window [#278](https://github.com/wez/wezterm/issues/278)
* New: [wezterm.pad_left](config/lua/wezterm/pad_left.md), [wwezterm.pad_right](config/lua/wezterm/pad_right.md), [wezterm.truncate_left](config/lua/wezterm/truncate_left.md) and [wezterm.truncate_right](config/lua/wezterm/truncate_right.md) function for truncating/padding a string based on its displayed width
* Updated bundled `Noto Color Emoji` font to version 2.020 with unicode 13.1 support. Thanks to [@4cm4k1](https://github.com/4cm4k1)! [#742](https://github.com/wez/wezterm/pull/742)
* Fixed: wezterm now sets argv0 to `-$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)
* Fonts: Changed the default [font_size](config/lua/config/font_size.md) to 12 points. [#517](https://github.com/wez/wezterm/discussions/517)
* Fonts: Updated bundled JetBrainsMono font to version 2.225
* 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: the portable .zip file download now includes ANGLE EGL, just like the setup.exe installer has done since version 20201031-154415-9614e117
* 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
font_hinting = "Full" # None, Vertical, VerticalSubpixel, Full
```
* Early startup errors now generate a "toast" notification, giving you more of a clue about what went wrong
* We now use the default configuration if the config file had errors, rather than refusing to start
* Wayland compositors: Improved detection of display scaling on startup
* Added `harfuzz_features` option to specify stylistic sets for fonts such as Fira Code, and to control various typographical options
* 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.
