unoplatform/uno 4.4.5

on GitHub

Uno Platform 4.4 is our 4th release in 2022, keeping us on a once-in-six-weeks rapid release schedule we aim for. The release packs numerous UI and performance improvements across all target platforms. First, on the UI side you’ll be able to produce beautiful fluid animations on .NET Android, .NET iOS and Skia-based targets, as well as increase high-fidelity renderings of all your texts on Skia-based targets. Second, on the performance side we are including support for the most recent WebAssembly advances available in .NET 7 – Wasm Threading and Exception Handling. Lastly, we also enabled new input scenarios via GamePad API support and improved the default project templates.
In total we have implemented and resolved over 90 new feature requests and issues.
