Highlights

SkiaSharp 2.80.0 rebases on Skia m80, brings Vulkan everywhere, and adds Linux ARM, Alpine, ARM64, and WebAssembly natives. Vulkan is now available on every platform that supports it, alongside a cleaned-up GPU API. Native coverage grows to Linux ARM32/ARM64, Alpine, and Win32 ARM64, plus a first WebAssembly build. SKFont becomes the canonical text/glyph type, and several disposal and GL crashes are fixed.

Breaking Changes

None in this release.

Engine

Rebased on Skia m80 — The bundled engine is refreshed from a much older Skia to milestone 80, bringing years of upstream rendering and text fixes into SkiaSharp. (#986)

API Surface

Vulkan on every supported platform — Vulkan support is built for Win32 alongside the existing platforms, with a shared managed API so consumers can target Vulkan the same way everywhere. (#1010, #1287)
GPU APIs cleaned up — The GPU surface is reworked for consistency across backends and to expose the pieces callers previously had to reach around. (#1294)
SKFont becomes the text/glyph type — SKFont's public API is now glyph-only, and the other text types are built on top of it — the canonical shape for text work going forward. (#1299)
New drawing and path helpers — SKCanvas.DrawTextOnPath, SKPath.ToWinding, SKPaint.ColorF, and image snapshots with bounds fill in gaps that consumers previously had to work around. — ❤️ @ziriax (#1198, #1326, #1325, #1357)

Bug Fixes

GL and shader crashes fixed — A crash when no GL context is present is resolved, the correct shaders are used, and GL ES 3.x is explicitly requested when available. (#1328, #1323, #1388)
Text and font lifetime corrected — The text blob builder and font set are now kept alive while in use, fixing intermittent crashes during text rendering. (#1365, #1362)

Lifecycle & Internals

Managed/native disposal reworked — The relationship between managed wrappers and native objects is disposed correctly again, closing a class of finalizer and use-after-dispose issues. (#1344)
Native library loading on desktop — Desktop and .NET Framework hosts now load a specific native library rather than relying on ambient search order, and libSkiaSharp is no longer embedded inside the managed assemblies. (#1342, #1296)

Platform

Linux ARM, Alpine, and Win32 ARM64 natives — Ships native libraries for Linux ARM32 (armhf) and ARM64 (aarch64), Alpine, and Win32 ARM64 — SkiaSharp now runs out of the box on those targets. (#1382, #1339, #1358)
WebAssembly build — There is now a libSkiaSharp build for WebAssembly and a matching WASM package, laying the groundwork for browser-hosted rendering. (#1359, #1389)

HarfBuzzSharp 2.6.1.5

HarfBuzzSharp 2.6.1.5 rides along with the SkiaSharp packaging, native library, and platform coverage work — the same builds now ship for Linux ARM, Alpine, and the other new targets.
