- - Fixed and improved UI-Test automation framework, and added new test cases for the FancyZones and Hosts module.
- - Optimized Logger function as AOT compatible, improving performance by 18%.
- - Made Common.UI and Setting.UI to be AOT compatible.
+ - Updated WinGet configuration file location and extension. Thanks [@mdanish-kh](https://github.com/mdanish-kh)!
+ - Removed the Markdown file bypass to ensure CI runs for commits that only update Markdown files.
+ - Fixed an issue where the default generated file path exceeded the length limit of 260 characters for EnvironmentVariablesUILib.csproj, causing build failures.
+ - Upgraded WindowsAppSDK to 1.6.250205002 and CsWinRT to 2.2.0. Thanks [@htcfreek](https://github.com/htcfreek) for review!
+ - Upgraded XamlStyler to 3.2501.8 and dotnet-consolidate to 4.2.0. Thanks [@davidegiacometti](https://github.com/davidegiacometti)!
+ - Updated .NET Packages from 9.0.2 to 9.0.3.
+ - Optimized the UI Test Automation Framework and added UI test cases for the Hosts File Editor module.
+ - Added fuzz testing for RegistryPreview.
+ - Added new UI tests for the FancyZones editor, including tests for creating, duplicating, editing, and deleting layouts.
+ - Added telemetry code to measure the module editor open time and evaluate the benefits of applying AOT.
