NumericUpDown and AutoCompleteBox: MaxLength, InnerLeftContent, and InnerRightContent.
WindowNotificationManager was refactored and now can be embedded at any level of the controls tree, not being hardcoded to the top level.

Avalonia now respects XGD accent color spec.

StaticWebAssets SDK is now supported. It brings support for building in .NET Brotli compression and caching. To use this SDK, please recreate the browser project from the new template using the 11.1.0-beta1 version.
WebGL2 is now enabled by default.

Metal rendering mode was implemented and now can be enabled via iOSPlatformOptions.

tvOS support was added.

iOS and Android backends now require .NET 8 or newer, as per .NET mobile workloads support timelines.
