New Features

Platform

  • .NET 8 readiness — Adds support for .NET 8 Preview 4, ships the new WebAssembly assets needed by Blazor on .NET 8, and keeps the release aligned with newer SDKs. ❤️ @jeromelaban (#2457, #2497)
  • WinUI JSImport path on .NET 7 — Moves the WinUI target over to JSImport and adjusts target resolution for newer Uno stacks. ❤️ @jeromelaban (#2428, #2503, #2529)
  • Broader Apple support — Adds .NET iOS and Mac Catalyst samples, packages iOS simulator RID artifacts, and supports ARM64 macOS build machines. (#2491, #2498, #2468)
  • Android AAR shipping — Includes the .aar payload directly in the Android NuGet package. ❤️ @dellis1972 (#2465)

Web & WASM

  • More capable WebAssembly builds — Adds multithreaded and multithreaded+SIMD variants, then enables exception handling and SIMD across all net8+ configurations. ❤️ @jeromelaban (#2286, #2495)

Bug Fixes

  • View disposal and guard fixes — Fixes SKCanvasView dispose-time exceptions and adds extra guard checks to avoid view lifecycle crashes. ❤️ @jjzhang12 (#2472), ❤️ @FoggyFinder (#2313)
  • Uno rendering correctness — Corrects SKXamlCanvas alpha handling on WebAssembly, defaults Opaque more safely on Apple-backed Uno targets, and refreshes swap-chain panel implementations. ❤️ @roubachof (#2443, #2398, #2400, #2401)
  • Tizen layout fix — Corrects canvas size calculation on Tizen. ❤️ @myroot (#2322)
