Dustin L. Howett has announced the release of Windows Terminal Preview 1.9.1445.0.

Features

• ALPHA FEATURE Windows Terminal Preview can now be set as the default console host on Windows Insider Dev builds ( #9907) ( #10170)
  • There are some known issues with this support; please see this query for the list of known bugs.
  • One such known bug is that you will need to resize the window before an application that spawned in Terminal becomes aware of its size. #9811
  • Another is that WSL doesn't work. At all. Sorry! #10134
  • If you still want to opt in, head over to the "Startup" section of the settings, or the "Terminal" section of the legacy console property sheet.
  • If you really need to run the traditional Windows Console, you can start it with conhost cmd or conhost powershell.
• Terminal now supports pinning an instance to the top of the screen that you can summon at any time (colloquially referred to as "Quake Mode") ( #9785) ( #9956) ( #9977) ( #10108) ( #10113) ( #10150)
  • It is bound by default to Win+` ( #10122)
    • You can rebind this shortcut with the quakeMode action.
  • This behavior will be granted to any window whose name is _quake. You can use wt -w _quake to target the quake window with commands.
  • You can add a custom binding to summon any Terminal window with the globalSummon action! ( #9854) ( #9954) ( #10092) ( #10025) ( #9963)
    • See the documentation on globalSummon for more details. This is a very flexible command!
• This version of Terminal comes with Cascadia Code 2105.24, which has an italic variant.
  • We're so excited to finally show this off!
  • Due to an issue, only the italic variant will display as version 2105.24.
• Terminal now supports mouse input for Windows console applications! ( #9970) ( #10138)
  • To the Far Manager folks ( @alabuzhev et al): thank you for being a good model application.
• You can now edit key bindings for existing actions on the Actions page ( #9949) and actually save them, too! ( #9926) ( #9621)
• The Appearance page will now show you a (tiny) preview of the Terminal ( #9527)
• We've added a new treatment for visual ( #9270)
• We have added a new "Add a new profile" page to the Settings UI, where you can choose to duplicate an existing profile ( #9352)
• We've added support for a focusPane action (focus by index) an the focus-pane/fp subcommand ( #10142)
• When you use the "Set color scheme..." action in the command palette, we will now show you a live preview of the new color scheme ( #9794)

Changes

• We have added support for the Windows (Super) key in key bindings (keyword win) ( #9783)
• There is now an experimental setting to disable URL detection ( #10022)
  • At global scope, set experimental.detectURLs to false, or visit the Interaction page in the settings.
• When you rename a window, we will now acknowledge that we actually did it ( #9808)
• Terminal will now show a more scrutable error message when your starting directory cannot be found ( #10045)
• Whitespace trimming in block selection can now be configured ( #9807) (thanks @Don-Vito!)
  • Use the trimBlockSelection global property (boolean, default false) or visit the Interaction page in the settings.

Performance

• Terminal is now built with profile-guided optimization for a bunch of common use cases ( #10071)

VT Support

• Terminal now has support for tab stops (which you will not notice, as it already had support for tab stops sorta) ( #9597) (thanks @skyline75489!)

Refactoring and Internal Improvements

• We have split TermControl into a Core, Interactivity, and Control layer ( #9820) ( #9980)
  • This will set us up very nicely for some of our vaguely menacing future plans.
• Conhost now has a mechanism for passing through DCS data strings ( #9307) (thanks @j4james!)
• We've replaced our attribute run storage with a new RLE vector that performs slightly better and is far, far more reusable ( #10099)

Bug Fixes

• There was an issue that would result in blank profiles or profiles containing just one setting; it is now fixed ( #9964)
  • The only known cause of this issue was editing the settings of a profile the first time you ever launch Terminal
  • If you have profiles named Default in your dropdown, this is probably why.
  • We will now attempt to heal settings files broken by this bug ( #10143)
    • If you did have a profile that you actually liked that didn't have a name or a GUID or any settings, it will now be broken.
      • (Why? That's just a Command Prompt profile with no useful identifying information in it...)
• We've fixed a bunch of instances of the terminal losing focus ( #10048) ( #10114)
• We will no longer close a tab on middle-click down (because up is much more reasonable) ( #9842) (thanks @Don-Vito!)
• The "close tabs to the right" and "close other" options have finally returned, thanks to some quick out-of-the-box thinking ( #9859) (thanks @mpela81!)
• Nested commands will no longer interfere with deleting the > command palette mode character ( #10164) (thanks @kovdu!)
• The "new tab" dropdown will no longer go up when it used to go down; we no longer live in topsy turvy-land ( #10009) (thanks @mpela81!)
• Terminal will no longer create a new profile with the name "Profile 13" if you're weird enough to add a new profile called "Profile 13" yourself (as an example) ( #9816) (thanks @Don-Vito!)
• The window rename action will no longer also pop keys into the terminal ( #9809) (thanks @Don-Vito!)
• You can now navigate better using your key bindings in the Settings UI (focus mode, fullscreen, etc.) ( #10121)
• Terminal will no longer let an application emit more than one bell per second ( #9812) (thanks @Don-Vito!)
  • In other news, a 1-second delay we accidentally introduced before a bell has been resolved ( #10133)
• The command palette will now respect your locale when you do a case-insensitive search ( #9943) (thanks @Don-Vito!)
• The "discard" button will try harder to keep you looking at the profile you're on ( #10147) (thanks @Don-Vito!)
• Terminal will try to keep the last selected pivot active when you move between profile pages ( #10047) (thanks @kovdu!)
• We fixed a bug that resulted in certain CJK punctuation characters being deleted ( 66b9b9d)
• Duplicating a tab will now attempt to copy its title, when that title was provided by you, the user ( #9813) (thanks @Don-Vito!)
• The "Use parent process working directory" and starting directory settings have learned to stop fighting back ( #9862)
• The various long tooltips in the application will now be wrapped more ~ ~ AESTHETICALLY ~ ~ ( #9913) (thanks @Don-Vito!)

VT Support

• We fixed some places where we deviated with the informal OSC 9;4 specification ( #10024)
• The text buffer will be initialized with the default attributes on a resize ( #5792)
  • This should mostly fix the issue where when you resize it floods with one color. Mostly.

Reliability

• We should no longer crash on exit nearly as often -- either exiting a shell or the application ( #10115) ( #10042) ( #10031)
• Typing --tabColor into the command palette now has a 100% reduced chance of crashing ( #10096)
• Pressing Save in the Settings window twice will no longer launch Terminal into the great beyond ( #10148)
• We fixed a rare crash, which mostly impacted conhost, when there were multiple client applications sending API requests at the same time ( c0ab9cb)

Performance

• Some of our debug logging was being enabled by accident, so we've restricted its activation further ( #10098)
  • This bug caused a significant reduction in rendering throughput!

WPF Control

• The WPF control can now have a background that varies from the terminal background ( #10026)

Documentation and Code Health

Thank you to @UnrealApex, @hms5232, @AKKaygin, @jBarrineau, @ghost1372 and @cliffkoh for documentation updates that keep this repository in fighting trim.

Additional thanks to @jsoref for maintaining the check-spelling action and keeping Terminal's spell checker up to date!
