New Features

Platform

  • WPF backend for Xamarin.Forms — Adds WPF support to the Xamarin.Forms views stack, expanding desktop UI options. (#917)
  • Apple platform packaging updates — Enables bitcode for watchOS and tvOS and adds arm64_32 support for watchOS. (#971, #967)
  • Desktop package refinements — Splits desktop projects and packages to better match platform-specific deployment needs. (#899)

API Surface

  • New graphics APIs — Adds bindings for SKPictureShader, SKTypeface.IsFixedPitch, and additional Unicode overloads to round out the core API surface. ❤️ @alexandrvslv, @Gillibald (#973, #1019, #972)
  • Span-based data access — Introduces Span<T>-focused APIs for data buffers, bitmap access, and text blobs to reduce copying and improve ergonomics. (#865)

Text & Fonts

Bug Fixes

  • View and lifecycle stability — Improves UWP GPU view stability and frees native resources when views are detached. (#1024, #1005)
  • Rendering correctness — Fixes transparent pixmap artifacts, color issues, and incorrect color-space ownership behavior. ❤️ @Odirb (#863, #1023, #922)
  • Memory management — Fixes a memory leak in SKRoundRect and avoids zero-byte raster allocations. (#995, #761)
