• New: split/pane support! CTRL+SHIFT+ALT+" to SplitVertical, and CTRL+SHIFT+ALT+% to SplitHorizontal.
• New: LEADER modifier key support
• New: window_background_opacity and window_background_image options to control using background images, transparent windows. More info
• New color schemes: Dracula+, Gruvbox Light, MaterialDarker, Overnight Slumber, Popping and Locking, Rapture, jubi, nord.
• New: expanded lua API allows handling URI clicks and keyboard events with lua callbacks. See wezterm.on docs.
• The GUI layer now normalizes SHIFT state for keyboard processing. If a keypress is ASCII uppercase and SHIFT is held then the SHIFT modifier is removed from the set of active modifiers. This has implications for your key assignment configuration; previously you would write {key="T", mods="CTRL|SHIFT"}, after updating to this release you need to write {key="T", mods="CTRL"} in order for your key bindings to take effect.
• Added show_tab_index_in_tab_bar option which defaults to true. Causes the tab's ordinal index to be prefixed to tab titles. The displayed number is 1-based. You can set tab_and_split_indices_are_zero_based=true if you prefer the number to be zero based.
• On Linux and macOS systems, wezterm can now attempt to guess the current working directory that should be set in newly spawned local panes/tabs, in case you don't have OSC 7 integration setup in your shell.
• We now bundle JetBrains Mono and use it as the default font, and add it as a default fallback font. Similarly, we also bundle Noto Color Emoji as a default fallback for emoji.
• Added automatically_reload_config=false option to disable automatic config reloading. When set to false, you will need to manually trigger a config reload (default: SUPER+R or CTRL+SHIFT+R)
• CloseCurrentTab now requires a confirm parameter.
• Halved the memory usage requirements per Cell in the common case (saving 32 bytes per cell), which gives more headroom for users with large scrollback.
• Reduced initial GPU VRAM requirement to 2MiB. Improved texture allocation to avoid needing lots of VRAM.
• macOS: Fix issue where new windows would open as Cocoa tabs when wezterm was maximized.
• macOS: Fix issue where wezterm wouldn't adjust to DPI changes when dragging across monitors or the screen resolution changed
• macOS: Reduced trackpad based scrolling sensitivity; it was hyper sensitive in previous releases, and now it is more reasonable.
• Fix an issue where EGL failed to initialize on Linux
• If EGL/WGL/OpenGL fail to initialize, we now try to fallback to Mesa OpenGL in software render mode. This should result in its llvmpipe renderer being used as a fallback, which has improved visuals compared to wezterm's own basic CPU based renderer. (This applies to X11/Wayland and Windows systems).
• Setting front_end="Software" will try to use the Mesa OpenGL software renderer if available (X11/Wayland/Windows). The old basic CPU renderer has been removed.
• The multiplexer server has been moved into its own wezterm-mux-server executable. You will need to revise your serve_command configuration.
• Windows: when started in an RDP session, force the use of the Mesa software renderer to work around problems with RDP GPU emulation.
• Fixed an issue with TLS Multiplexing where bootstrapping certificates would usually fail.
• Windows: Fixed an issue that prevented ALT-Space from showing the system menu in the window.
• Windows: Fixed dead key handling. By default dead keys behave the same as in other programs and produce diacritics. However, setting use_dead_keys = false in the config will cause dead keys to behave like a regular key; eg: ^ would just emit ^ as its own character.
• Windows: Fixed an issue with the Hide key assignment; it would hide the window with no way to show it again! Hide now minimizes the window instead.
• macOS: we now use Metal to render the gui, via MetalANGLE
• Windows: we now prefer to use Direct3D11 to render the gui, via ANGLE EGL. The primary benefit of this is that upgrading your graphics drivers while you have a stateful wezterm session will no longer terminate the wezterm process. Resize behavior is not as smooth with ANGLE as the prior WGL. If you wish, you can set prefer_egl = false to use WGL.
• Improved image protocol support to have better render fidelity and to reduce VRAM usage when the same image it displayed multiple times in the same pane.
