New Features

GPU & Rendering

  • Metal APIs for Apple platforms — Adds Metal support for macOS and iOS bindings, opening the door to newer Apple GPU backends. (#1394)
  • Runtime shader support — Introduces the SKRuntimeEffect API so applications can compile and run custom SkSL effects. (#1604)
  • More GPU control points — Exposes GRContextOptions and IsAbandoned so apps can better inspect and configure GPU resources. (#1529, #1659)

Platform

  • WinUI and Uno expansion — Adds support for WinUI Desktop and the Uno Platform SKXamlCanvas backend. (#1696, #1704)
  • Interactive and WebAssembly scenarios — Adds .NET Interactive support, broadens WebAssembly packaging, and introduces an ARM64 build target. (#1710, #1590, #1627)

Images & Documents

  • More metadata and serialization APIs — Adds Exif SubIFD reading plus bindings for serializing SKPicture content. (#1518, #1514)

Bug Fixes
