Windows Terminal Preview v1.22.2362.0

This is, perhaps, the largest release of Windows Terminal to date. I can't believe we're here, but we finally have support for Sixels and a new console hosting infrastructure (stay tuned for a NuGet package!) and more. Read up, and read down, to find out more.

Features

• Terminal and conhost now support Sixels! 🎤🫳 (#17421) (thanks @j4james!) (#17724) (thanks @j4james!) (#17581) (#17636)
• We have rewritten how hosted console applications are translated for Windows Terminal (and other ConPTY consumers) to be based on direct API->VT translation rather than "rendering" a point-in-time snapshot of the display. This should result in improved throughput, reliability, correctness, plus an ability for applications to send unmodified VT directly to the terminal, but may result in some compatibility issues. Please file any issues you encounter with console applications. (#17510) (#17645) (#17741) (#17757) (#17748) (#17442) (#17573)
  • ... terminals which support DEC rectangular operations DECCRA and DECFRA should see higher fidelity app-based scrolling (#17747)
• We now support a much wider range of Unicode, including Emoji with ZWJ, combining characters, flag sequences, and anything else that requires proper Grapheme Clusters! Applications can query support for grapheme clusters with DECRPM 2027, and users can now configure whether Unicode is measured like the vintage Windows Console, like Linux and macOS terminals using wcwidth, or with Grapheme Clusters like Contour and other modern terminal emulators. Global setting compatibility.textMeasurement (enum console, wcswidth, graphemes (default)) (#16916) (#17443)
• For the first time in decades, we've changed the popup UI (used for F7 and friends) in CMD! It now draws beneath the prompt (pushing the screen up) and has a modern TUI scrollbar if it doesn't all fit on the screen. (#17445) (#17668) (#17556)
• Terminal will now offer relevant packages from WinGet if you're running CMD on Windows 24H2 and run a nonexistent command (#16848) (#17614)
• You can now add actions like splitPane and sendInput: foo and quit directly to the New Tab dropdown menu! (#17281)
• You can now open a pane containing snippets (any sendInput actions!) with the openSnippets action! You can quickly access any commands you've saved in your JSON file, or with the new x-save command, and replay them with a new slick UI (#17330) (#17794) (#17528)
  • ... snippets which can also be loaded from a .wt.json file in your current working directory (we're still working on docs, please stay tuned!) (#17388)
  • ... snippets which can also be saved directly from the command line with wt x-save "text to save" (#16513) (thanks @e82eric!) with additional fixes (#17758)
• Ctrl+Shift+Period will now open the "quick actions" flyout, which contains snippets and suggestions. You can now also bind the quickFix action to open a menu containing only WinGet suggestions (as of today, on Windows 24H2) (#17502)
• You can now search with regular expressions in Terminal (and conhost!) (#17316)

Changes

• ReadConsoleOutput and WriteConsoleOutput will now handle out-of-bounds conditions as documented rather than as-made-up (#17567)
• Actions now have their own IDs, and key bindings just point at them; we've made changes to how this works to improve the action and binding experience in future versions (#17162) (#17215)
• Command/input previews will now display in line with the cursor, in italic, in the right font (#17386) (#17777) (#17533)
  • ... which you can display in RGB with the fun {profile}.experimental.rainbowSuggestions setting (boolean, default false) (#17416)
• Commands displayed in the suggestions UI can now include descriptions (#17376)
• Multi-cell glyph inputs will no longer be assumed to consume two code units (#17680)
• Pixel shader authors rejoice! If your shader fails to compile, you'll now get a useful error message... (#17436) (thanks @blitzRahul!)
• Terminal will now no longer correct SGR 37 and SGR 40 when emitted by powershell.exe; this may result in regions of incorrect colors (#17666) (#17685) (additional thanks @j4james for some cleanup!)
• Vintage console applications will no longer get corrupted responses from ReadConsoleOutput when Raster Fonts are enabled (#17681)
• We have brought the new Windows 24H2 API out to the ConPTY NuGet package (#17704)

• We're now collecting data on which settings and actions folks are using (#17718) (#17678)
• We're trying something new, which is putting a short version of these release notes on the Windows Store (#17730)
• We've changed the communication mechanism for the Default Terminal feature to allow the use of overlapped I/O (#17575)

• When we reload a saved session, we will now display some of its contents on the screen (#17334)

UI

• We've rewritten how selection colors work! They will now be drawn with appropriate contrast, at the exact color you specify, with a foreground that is black or white (whichever is most visible!) (#17753) (#17725) (#17638) (#17676)
• The search box will no longer cover up search results in the top right (unless there's nowhere to scroll) (#17516) (thanks @e82eric!)
• Due to a build issue, we had to disable full optimization for this build. We apologize for any potential performance regressions. (#17765)
• Terminal now comes with shiny new icons for the Visual Studio Dev Shells (#17706)
• We have restored the ...s in some command palette names to help users find them (#17715)
• You can now configure the theme for the Settings UI separately from the application with {theme}.settings.theme (enum light, dark, system; default: system) (#16479) (thanks @bundgaard!)

VT Features

• You can now configure the "Answerback" message sent in response to ENQ using the profile setting answerbackMessage (string, default: null) (conhost users: HKCU\Console AnswerbackMessage REG_SZ) (#17660) (thanks @j4james!)
• We now support the DEC VT paging operations, NP PP PPA PPR and PPB, as well as DECPCCM (page cursor coupling mode) and DECRQDE (request displayed extent) (#16615) (#17353) (thanks @j4james!)
• Applications can now request the entire color palette using DECRQTSR DECCTR (CSI 1 ; Pt $ u) (#17708) (thanks @j4james!)
