Windows Terminal Preview v1.23.10353.0

[DHowett]

The holiday season struck during the development of Terminal 1.23, so the changelog is a little shorter than usual. Even so, we're here with a new windowing architecture and some new fonts and color schemes. Enjoy, and please remember to file bugs and tip your waiters!

Features

• Multi-windowing has been rewritten to be much more reliable and robust; the tray icon now works more consistently, actions spanning multiple windows trigger properly, summoning works better, and a whole host of other things are better. If you encounter any issues with windowing or process management, please file a bug! (Remove Monarch/Peasant & Make UI single-threaded #18215) (Fix dispatching of system keys #18444) (Fix cursor hiding on input #18445) (Pass foreground rights to the emperor #18325) (Fix multiple regressions since #18215 #18345)
• This version of Windows Terminal comes with Cascadia Code 2407.24; this version fixes a hinting issue in Arabic glyphs (Update Cascadia Code to 2407.24 #18499)
• We're piloting a new color scheme, "Ottosson", which offers well-distributed and consistent hue and chroma based on the Oklab color space (Add Oklab based color scheme "Ottosson" #18502)
• You can now turn on the tab bar for full-screen Terminal windows using a new setting (showTabsFullscreen, boolean, default false) (Add the ability to show the tab bar in fullscreen #18171) (thanks @GeekJosh!)
• Settings UI Overhaul!
  • There is a new New Tab Menu customization experience, in a new top-level settings page, that lets you add folders and profile matchers and more to your New Tab menu! (Add New Tab Menu Customization to Settings UI #18015)
  • We've added a new Compatibility page at the top level and a Terminal Emulation page inside Profiles to control application compatibility settings (Add a Compatibility and Terminal page to the Settings UI #17895)
  • A handful of simpler settings like "rainbow suggestions", "cell width", "web search URL query", "color selection" and more are finally available as easy toggles (Add miscellaneous simple settings to the settings UI #17923)
  • You can now easily set up bell sound (or sounds!), play them back to sample them, and remove them (Add Profile.BellSound to Settings UI #17983)
  • Profiles have long been able to override the foreground, background and selection colors from their color schemes, but you haven't been able to set them via the UI. You now can! (Add nullable colors and improve Profile.Icon in settings UI #17870)
  • We've implemented an icon picker that lets you easily input emoji, pick built-in icons, or choose icon files (Add nullable colors and improve Profile.Icon in settings UI #17870)
  • The appearance page sports a new fancy spatial padding editor (Add separate padding settings for left, top, right and bottom #17909) (thanks @nukoseer!) (Unify padding parsers, make SUI operate on struct Thickness #18300)
• You can now configure the translation of paths dropped on or copied into Terminal to use one of four styles: None (Windows, no translation), WSL (/mnt/c), MSYS2 (/c) or Cygwin (/cygdrive/c) via a new profile setting pathTranslationStyle (enum none, wsl, msys2, cygwin; default none except for WSL profiles) (Add a new (advanced) profile setting, pathTranslationStyle #18195)
• You can now copy the contents of the screen with escape sequences! Add a new copy action with "withControlSequences": true to use it (Allow copying with ANSI escape code control sequences #17059) (thanks @FuegoFro>!)
• Applications can now use the S8C1T and S7C1T escape sequences to enable or disable C1 controls; in addition, DOCS will turn on 8-bit control characters on stdin when it is used to enable ISO2022 encoding (Add support for the S8C1T/S7C1T escape sequences #17945) (thanks @j4james!)

Changes

• Applications can now resize the Terminal window (if it contains a single pane and tab) using CSI t (DTTERM Window Manipulation) (Handle window resize event (CSI t, resize) #17721) (thanks @nukoseer!)
• Automatically-detected profiles which are no longer detected (because they were uninstalled, or in the case of WSL distributions unregistered) will be saved and displayed in Settings with an indicator (Retain (and indicate) orphaned dynamic profiles #18188) (Don't allow orphaned profiles to show up in the Default Profiles #18207)
• Focus will move rightward rather than leftward when you close the active tab (Changed new tab index on tab close to next tab #18022) (thanks @michaeljsXu!)
• In cmd and python (and other users of console line input), choosing a command from history will once again duplicate it in your history; this reverts Dedup command history by default #17852 (Revert "Dedup command history by default (#17852)" #18229)
• On Windows 11 24H2, Terminal will no longer be updated while it is in use (this might look familiar! There was an issue preventing this from working until this change landed) (Add 10.0.26100.0 to MaxVersionTested #18252)
• Text selections will now begin on the nearest half-cell, mimicking behavior seen in text editors like Notepad, and will only cover a cell if more than half of it is in-range; screen readers will now properly detect empty selections (since we can now represent empty selections!) during mark mode (Make selection an exclusive range #18106)
• The POSIX-style path translation modes will (finally!) properly escape paths containing single quotes (Escape single quotes while translating dropped Win32 paths #18007) (thanks @a4lg!)
• The settings UI now contains options to disable (or enable, I guess!) specific warning dialogs such as the ones for multi-line paste and closing all tabs in a window (Add Warnings to Settings UI #17933)
• When customizing the New Tab menu, you can now override the icon for each entry (Add icon override setting for newTabMenu entries #18116) (thanks @GeekJosh!)
• You can now bind an action to open the current working directory (as reported by OSC 9;9) in File Explorer (action openCWD) (Open current working directory action. #18013) (thanks @michaeljsXu!)
• You can now bind an action to open the directory containing settings.json (openSettings action, target directory) (Add action for opening settings directory in file explorer #17690) (thanks @e82eric!)
• You can now disallow applications from writing to the Windows Clipboard (profile setting compatibility.allowOSC52, boolean, default true; Terminal Emulation settings) (Let folks disable OSC 52 #18449)

Bug Fixes

• Ctrl+Insert will (finally!) copy selected text in the Command Palette (Fix Ctrl+Insert does not copy the selected text from Command Palette #18483) (thanks @eleadufresne!)
• conhost: when you drag snapped windows between monitors of different DPIs, it will no longer resize at random ([conhost] Fix WM_GETDPISCALEDSIZE handler, use provided size instead of current window size #18268)
• Tab background colors will now work more reasonably in High Contrast mode (Fix tab contrast colors when in high contrast #18109) (Fix colored tab losing color when unselected #18306)
• Screen reader users can now read all of the preview text in the Settings window (Make SUI previews readable by screen readers #18418) (Fix SUI crash when image alignment not centered #18481)
• The "Close Window" action will no longer bypass the close confirmation dialog (Fix 'closeWindow' ignoring confirmation #18434)
• The font picker in the Settings > Appearance page is now navigable by keyboard, and selections made there will actually save (Stop updating AutoSuggestBox on selection redux #18010)
• We've rewritten a lot of our mouse input handlers to avoid rounding away fractional pixels and improve accuracy (Use floating DIPs throughout the stack #18027)
• You can now close tabs with the middle mouse button even when the close button is hidden (Allow closing tabs with middle mouse button when close button is hidden #15924) (thanks @kasper93!)
• The schema document has been updated to include the Windows.Terminal.VisualStudio dynamic profile source (Add "Windows.Terminal.VisualStudio" to schema #18322)
• compatibility.textMeasurement is now present in the JSON settings schema document (Update settings schema for compatibility.textMeasurement #18277)

Reliability

• Terminal will no longer occasionally hang when an IME is in use which calls back into the application while composition is ongoing (Fix infinite recursion in TSF #18248)
• We have fixed a reliability issue in some of our deferred actions (such as scanning the text buffer for URLs) (Defuse throttled_func when it's accidentally engaged #18235)

Console APIs and VT

• Client applications will once again be closed in newest-to-oldest order, and CTRL events will be processed for all clients even if one had failed during event processing (Fix order and robustness of CTRL_*_EVENTs #18233)
• Repeated console API calls that transit less than 128KiB of data will no longer cause heap thrashing (Reduce malloc churn for console calls <=128KiB #18287)
• The new readline implementation in 1.22 will now work more consistently in the face of concurrent output (Reduce likelihood of races between stdout and cooked stdin reads #18326)
• ReadConsoleInput will no longer spuriously return success and read 0 characters (Properly implement WaitForData for ReadConsoleInput #18228)
• Zero-width control characters will now be joined with their preceding grapheme clusters rather than being allocated individual cells (Fix clustering of gc=Cf, GCB=CN codepoints #18285)

Miscellaneous Changes

• Terminal now comes with a Markdown parsing library, aptly named "Sir Not Appearing In This Release" (Add support for markdown -> XAML parsing #17585)

With additional engineering system, CI, code health, documentation, schema and packaging fixes from @Jewelry-x, @Jvr2022, @jsoref, @Tarang74, @Dan-Albrecht, @michaeljsXu, @raghav2005, @AsciiWolf, @YexuanXiao, and @mitchcapper!
