Prerelease: no

Release notes: This is the second release candidate build of Windows Package Manager v1.12. If you find any bugs or problems, please help us out by filing an issue.

New in v1.12

• Initial MCP server implementation available; run winget mcp for assistance on configuring your client.
• App Installer now uses WinUI 3. The package dependency on WinUI 2 has been replaced by a dependency on the Windows App Runtime 1.8.
• Manifest schema and validation updated to v1.12. This version update adds Font as an InstallerType and NestedInstallerType.
• Font Install, Uninstall, and a winget-fonts source have been added and are non-experimental.

Bug Fixes

• Manifest validation no longer fails using UTF-8 BOM encoding when the schema header is on the first line
• Upgrading a portable package with dev mode disabled will no longer remove the package from the PATH variable.
• Fixed source open failure when there were multiple sources but less than two non-explicit sources.
• Fixed a failure that would happen while closing App Installer.

Font Support

Font Install and Uninstall via manifest and package source for user and machine scopes has been added. A sample Font manifest can be found at: https://github.com/microsoft/winget-pkgs/tree/master/fonts/m/Microsoft/FluentFonts/1.0.0.0

At this time install and removal of fonts is only supported for fonts installed via WinGet Package.

Fonts must either be the Installer or a .zip archive of NestedInstaller fonts.

A new explicit source for fonts has been added "winget-font".

This source is not yet accepting public submissions at this time.

## Experimental Features
* Experimental support still exists for the 'font' command.

---
### Experimental support for Fonts
The following snippet enables experimental support for fonts via `winget settings`. The `winget font list` command will list installed font families and the number of installed font faces.

{ "$schema" "https://aka.ms/winget-settings.schema.json", "experimentalFeatures": { "fonts": true } }

The font 'list' command has been updated with a new '--details' feature for an alternate view of the installed fonts.
