Highlights

SkiaSharp 4.151.0 previews the Skia m151 engine update ahead of the stable release. It brings the current upstream renderer into the 4.151 line and keeps WebAssembly builds clean without changing the managed API surface.

Breaking Changes

None in this preview line.

Engine

  • Skia updated to milestone m151 — Aligns the bundled renderer with Chrome milestone 151, giving preview consumers the latest upstream engine while preserving SkiaSharp's managed API surface. (#4294)
  • WebAssembly build warnings removed — Drops the duplicate SK_BUILD_FOR_WASM define from the Skia submodule so Emscripten builds no longer report macro redefinition noise. — ❤️ @ramezgerges (#3788)

HarfBuzzSharp 14.2.1

No HarfBuzzSharp binding changes shipped in this release — it rebuilds the same HarfBuzz as the previous line.
