Windows Terminal Preview v1.24.2372.0

[DHowett]

Like a famously-hibernating animal coming out of a long sleep, Terminal Preview is back to eat a bunch of berries visit your machine with all of its new peculiarities.
We took a whole quarter off to focus on 1.23's stability, so this release might seem lighter than usual. That's only because we backported hundreds of changes to the now-stable 1.23!

We've changed how icons work, and now we let fragment authors include pixel shaders and stuff. It's a pretty cool release, so buckle up:

Features

• Command Palette will now be displayed (and searchable!) in both your native language and English (assuming your native UI language is not already English) (Filter the Command Palette in English in addition to locale #19166) (Rewrite HighlightedTextControl and remove HighlightedText #19130) (Command: realize resource-key names when they are requested, not at load #19165) (Undo the damage done to FilteredCommand in #17330 #19148) (Expose a library's Resource Loader, allow a user to "subset" it #19131)
  • ... it now also uses the fuzzy searching algorithm popularized by fzf (which feels way more intuitive!) (Update command palette search to prioritize "longest substring" match. #18700) (thanks @e82eric!)
• Icons, background images, and pixel shader paths can now refer to files relative to your settings file, whether you are a user or a fragment author. Learn more about distributing media resources with a fragment extension! (Rewrite media resource handling (relative path icons, web URLs) #19143) (Profiles Editor: make sure we notify the IconPath property #19223)
• Settings has a new Extensions page, where you can see (and disable!) the sources for all your profiles, color schemes and extra actions (Add Extensions page to Settings UI #18559) (Replace extensions page hyperlink with fwlink #18997)
• Terminal will now try to automatically detect hosts you may SSH to often (using your ssh_config) and generate a folder of quick-access SSH profiles (Enable SSH Generator Feature Flag and polish UI #18814) (Add SSH folder to NTM for dynamic profiles #19239)
• The matchProfiles new tab menu entry now supports regular expressions (so you can match .*\.WSL, for example!) (Replace New Tab Menu Match Profiles functionality with regex support #18654) (Apply localization and documentation fixes for regex code #18914)
• The right-click context menu now affords you quick access to splitting, moving, zooming and closing panes! (Updated pane context menu #18126) (thanks @dm17ryk!)
• We now support DEC private mode 2026, Synchronized Output! This gives screen-buffered applications a chance to complete rendering a frame before we display it on the screen (Implement DECSET 2026 - Synchronized Output #18826) (Use RenderSettings for DECSET 2026 - Synchronized Output #18833)
• We've added another core color scheme, Dimidium, based on the CAM16 color model (Add CAM16 based color scheme "Dimidium" #18563) (thanks @dofuuz!)
• You can now disable the Ctrl and Ctrl+Shift mouse wheel shortcuts to change the font size (zoom) and opacity of the terminal (feat: add option to enable zoom with ctrl + scroll #19127) (feat: add option to adjust opacity with Ctrl+Shift+scroll #19151) (thanks @paulinek13!)

Changes

• Bracketed pastes (via DEC private mode 2004) will no longer have trailing newlines removed; in addition, we have expanded the "multi-line paste warning" setting to allow you to enable it in more cases (Don't trim bracketed pastes #19067)
• Hovering over color scheme entries (and other previewable things) in the command palette will now also preview them (Feat preview color scheme on mouse hover #18518) (thanks @eleadufresne!)
• If your system is using "high contrast" mode, Terminal will now automatically turn on perceptual color nudging (unless you have disabled it completely) (Automatically enable AdjustIndistinguishableColors if High Contrast mode enabled #17346)
• We've tightened up the settings UI and about dialog to make them more consistent and--dare we say?--more polished ([UX] Settings UI refinements #19001) (Update key chord styling in actions page #19164) (Tweak spacing on about dialog #18993) (thanks @niels9001!)
• When you have session restoration enabled, we will now routinely save window layouts (not contents) to make sure Terminal comes back looking roughly the same in case of a crash (Persist window layout every few minutes #18898)
• When you have snippet loading enabled, Terminal will now read .wt.json files from parent directories to the one you are in (as determined by OSC 9;9) (Load .wt.json snippets from parent directories #18904)
• You can now configure an additional path translation mode, MinGW (mingw in JSON), which will map paths like C:\foo to C:/foo (TerminalControl: Support MinGW path translation style (C:\ -> C:/) #18759) (thanks @abutcher-gh!)
• The defaults profile will no longer remember values for the unsupported keys name, guid, source or commandline (Clear Name, Source, and Commandline from Profiles.Defaults #19225)
• We have added quick access and highly destructive "delete all my settings" and "delete all my cached info" buttons to the Settings UI (Add reset cache and settings buttons to SUI #18907)

Bug Fixes

• Sixels: color handling during scrolling should now behave more faithfully to the VT330 and VT340, filling with the active background color rather than the original one (in background select modes 0 and 2) (Improve correctness of Sixel background fill #18260) (thanks @j4james!)
• Tab icons, close on exit state and the bell settings will once again be reloaded when the settings file changes (Fix hot reload for icon, bell, close on exit; regressed in #16172 #19217)
• Terminal will no longer occasionally miss hard line breaks in full-screen applications such as tmux (Speculative: remove overeager line wrapping in AdaptDispatch #18899)
• We accidentally left some duplicate data in the default settings file; it is no longer duplicated (Remove duplicate entries from defaults.json #18527) (thanks @joca-bt!)
• We will no longer try to render bidirection text isolates LRI, RLI, FSI and PDI (fix: don't print bidi isolates LRI, RLI, FSI, PDI #18942) (thanks @adalinesimonian!)
• WSL profiles containing local overrides for the PATH environment variable will no longer destroy the PATH inside WSL (Fix WSL PATH corruption & potential use-after-free #19211)
• Terminal will now actually spawn all processes in windows and tabs created consecutively from the same wt invocation (Throttle incoming handoffs so WinUI can layout them #19220)
• The "Default Terminal" selector will no longer be misaligned in some cases (Center text of default launch terminal #19072) (thanks @HO-COOH!)
• Turning "Use active terminal title as application title" (JSON showTerminalTitleInTitlebar) on and off will no longer result in your window titles becoming stuck (Fix title being stuck after toggling "showTerminalTitleInTitlebar" #19212)
• Terminal's launch size now takes into account any custom cell width and height you may have specified (Account for custom cell sizes in launch size calculation #18862) (thanks @j4james!)

Performance and Reliability

• Buffers with a lot of scroll bar marks should be handled faster (Fix a output marks performance regression #19242)
• Dragging invalid paths onto Terminal (actually, ones with incorrectly-constructed DataObjects) will no longer send your session into outer space (Ensure items is not null before checking its size so we dont crash #19026) (thanks @jamespack!)
• Terminal will now attempt to delegate foreground priority to processes in the active tab (on some versions of Windows 11) (Use a new API to propagate foreground state to child processes #19192)
• The experimental "reposition cursor on click" will no longer cause "snap on input" to, well, snap, as though input has been put in (fix(ControlCore): prevent cursor repositioning during mouse selection #19182) (thanks @MengAiDev!)
• We have resolved a crash in context menu handling across multiple windows (Implement custom text context menus to fix crashes #18854)
• Updating the title millions of times per second will no longer deadlock the UI (also, we improved our implementation of function debouncing across the board) (Extend lead/trail edge support for throttled_func #19210)

Windows Console and WPF Control changes (pending release)

• conhost: selection and color search will no longer come up one character short ([Conhost] Fix off-by-1 error when copying and coloring selections #19259)
• conhost: we will now cnap on input and output more reliably in WSL and PowerShell (Fix SnapOnOutput not always snapping #19247) (Implement snap-on-input/output for conhost #17453)
• conhost: when Win32 Input Mode is enabled, we will request that it be disabled as part of PTY teardown (Disable WIN32IM on shutdown #19229)
• conhost: the console now supports OSC 52 (Manipulate Selection Data) to write to the clipboard (Add support for OSC 52 clipboard copy in conhost #18949) (thanks @j4james!)
• wpf: the WPF control no longer builds for .NET 6 and .NET Framework 4.8, opting instead for 8 and 4.7.2 (Remove dependency on .NET 6 and Framework 4.8 #19199)
