Windows Terminal 1.9.1942.0

This release brings many of the preview changes in Windows Terminal 1.9 to the stable channel.

You may not yet see this release in the Store. We are trying a new "slow rollout" system that follows the Windows Insider program. You can always install a new build from this repository!

Notable changes include:

• 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)
• Terminal now supports mouse input for Windows console applications! (#9970) (#10138)
• The Appearance page will now show you a (tiny) preview of the Terminal (#9527)

Please note that the following features are not included in the 1.9 stable release:

• The ability to set Windows Terminal (stable) as the default console application host
• The live action editor in the Settings UI

Please see the following release notes for additional details:

• Windows Terminal Preview v1.9.1445.0
• This release includes changes from an undocumented v1.9.1523.0 release. These changes will be indicated below.

A preinstallation kit is available for system integrators and OEMs interested in prepackaging Windows Terminal with a Windows image. More information is available in the DISM documentation on preinstallation. Users who do not intend to preinstall Windows Terminal should continue using the msixbundle distribution.

We've also backported the following changes and bug fixes from Windows Terminal Preview 1.10.1933.0:
