4.7.30

Our first release of 2023 is ready and brings over 230 new features and bug fixes, most notably introducing a new project template, improving performance across all platforms supported by Uno Platform and Shared Fonts.

Here are some highlights of the release:

• An updated project template which uses a Class Library instead of a "Shared Project"
• Support for Shared Fonts assets, which is removing platform specific steps
• Support for ms-appx:/// Uris Images in library assets
• Support for AppointmentStore (Android) by @pkar70
• XAML Trimming improvements (e.g. 33% in the Calculator app)
• Support for ISelectionRange
• .NET 7 performance improvements with JSImport/JSExport
• Markup extension in Style Setter
• Readonly TextBox selection support
• .NET Native AOT support for the Skia GTK and Framebuffer heads
• Framebuffer fixes for 32 bits depths
• Android interop performance improvements

More details can be found in our blog post!

See below for the complete changelog.

BREAKING CHANGES

• assets: The ms-appx:/// specifier for libraries introduced in Uno Platform 4.6 was incorrectly lower-casing the library name. This change now uses the original name used by the library, which is the AssemblyName property of the library hosting the assets.
