Microsoft has released a new preview build of Windows Package Manager, introducing new features and fixes. The App Installer now uses WinUI 3, replacing the package dependency on WinUI 2. Manifest validation no longer fails using UTF-8 BOM encoding when the schema header is on the first line. Experimental features include experimental support for fonts via winget settings. Changes include updating other TDBuild tasks, using windows-latest agents in localization pipeline, bumping version to v1.12, allowing foreground from PS, moving to proper signal for dev/not-dev, using SDK 26100 in CommonCore project, and repairing Repair-WinGetPackageManager.
