We're excited to announce our second release for 2023, which includes over 200 fixes and product improvements, as well as support for .NET 8 Preview 2.

As promised, we've been hard at work on the improvements you requested in our 2023 Roadmap survey. One of the top requests was to make the startup experience with Uno Platform as seamless as possible. In response, we've introduced a new startup experience designed to make setting up new projects with Uno Platform easier and more flexible than ever before. The Uno Platform Templates wizard will guide you through setting up your project, allowing you to choose as many or as few pieces of Uno Platform as you desire. So, starting a new Uno Platform project is easier than ever moving forward!

As with every release we also spent significant effort in improving performance across all supported platforms. In addition to multiple in-memory and runtime performance improvements we are introducing OpenGL acceleration for Uno Islands, which are typically used in WPF modernization scenarios, showing 12x improvement over software rendering. In addition, TextBlock rendering for all Skia backends, showing 5x improvements in common scenarios.

Here are some additional noteworthy improvements:

  • ThemeShadow for iOS/Catalyst/Android
  • Shadows on Skia targets
  • Performance and memory improvements
    • Memory improvement in XAML SourceGenerator
    • Runtime performance and memory improvement in DependencyObject
    • Memory improvements in ItemsControl and ContentControl
  • GTK+Linux fixes for Ubuntu 23.04+ and Arch distributions

As always, a big shoutout to everyone who worked closely with our core contributor team to make this release possible:
