This is a quick servicing release to address a number of issues in the 1.6 preview release.

Changes

• This version of Windows Terminal comes with Cascadia Code 2102.03, which offers 23 bug fixes, support for new glyphs, control pictures, infinite arrow ligatures and more! (#9088)
  • See the Cascadia Code February 2021 Update release for more information.
• If you completely delete settings.json while WT is running, it will now generate a new one (#9012)

Bug Fixes

• The window titlebar, once a sacred place, will now be updated correctly when terminal titles and tabs change (thanks @sarim!) (#9054)
• Pixel shaders that rely on the time input will now actually work (thanks @Nacimota!) (#8994)
  • They'll also now update at 60fps (or whatever)! This will almost certainly tank your battery life, but you didn't sign up for pixel shaders because you like batteries (#9091)
• Right-clicking in the tab renamer should no longer cause it to stop renaming (thanks @Don-Vito!) (#8979)
• Right-clicking in the command palette should also no longer cause it to stop commanding (or paletting) (thanks @Don-Vito!) (#9057)
• We now better track the hidden/shown state of the cursor when you're typing to prevent it from being lost forever(*) (thanks @Don-Vito!) (#8952)
  • (*) sometimes it still gets banished to the Land of Lost Things
• Hyperlinks, which started to underline even with the window out of focus, should now properly de-underline when out of focus (thanks @Don-Vito!) (#9039)
• We fixed an issue where we mis-parsed OSC 9;9 directories wrapped in double quotes (thanks @skyline75489!) (#8934)
• You should now be able to use Ctrl+C and Ctrl+V in the command palette even if they're bound in your terminal (thanks @Don-Vito!) (#9056)

Settings UI (Preview)

• We've stopped accidentally deleting disabledProfileSources from your settings. Sorry! (#9038)
• The "Launch Mode" and "Tab Switcher Mode" switches in the settings page now work properly (#8956)
• Renaming a color scheme in use by the base layer will no longer corrupt all your other color schemes (#9103)

Reliability and Performance

• The "Open Windows Terminal Here" shell extension will no longer throw a cryptic error about servers (thanks @hereafter!) (#8977)
• The terminal should no longer crash if you close a tab while it's printing text [whoops] (thanks @j4james!) (#8982)
• We've stopped crashing or displaying random errors about a blank pixel shader path (#9092)
• schemes:[] or schemes:[{}] should no longer cause a crash on launch (#8995)
  • (There were a few scenarios that would cause this, but this is the easiest to write a release note about.)
• No longer will we crash when you right-click and close a tab containing multiple splits (#9028)
• We had to disable the "Close..." submenu because of a platform issue that resulted in a crash (#9102)
