Highlights

Version 2.80.0 is a major platform release built on Skia milestone 80, with broad GPU work, first-class Vulkan support, and the first official WebAssembly and new ARM native packages in this line. It also expands the managed API surface with new text, color, path, and snapshot APIs, while shipping with HarfBuzzSharp 2.6.1.5 for the aligned shaping bindings.

Breaking Changes

None called out for this release.

New Features

Engine

  • Skia milestone 80 — Updates the underlying engine to a much newer Skia milestone and carries that work through the 2.80 release family. (#986)

GPU & Rendering

  • Vulkan support across supported platforms — Brings Vulkan support to Win32 and broadens the GPU stack across the supported native targets. (#1010, #1287)
  • Expanded GPU APIs — Improves the GPU-facing managed APIs and adds snapshot support with bounds for easier diagnostics and capture. (#1294, #1357)

Platform

  • WebAssembly support — Adds libSkiaSharp for WebAssembly, the corresponding package work, and initial WASM unit-test coverage. (#1359, #1361, #1387, #1389)
  • Broader native package coverage — Adds Linux ARM32/ARM64, Win32 ARM64, and Alpine native libraries while improving desktop native library loading. (#1382, #1358, #1339, #1342)

API Surface

  • New drawing and color APIs — Adds SKCanvas.DrawTextOnPath, SKPaint.ColorF, and SKPath.ToWinding, plus text API work that aligns SKFont more closely with glyph-based operations. ❤️ @ziriax (#1198, #1325, #1326, #1299)

Bug Fixes

  • Lifetime and disposal fixes — Keeps text blob builders and font sets alive when required and revisits managed/native ownership to prevent premature disposal. (#1365, #1362, #1344)
  • Startup and packaging correctness — Fixes package composition, avoids embedding libSkiaSharp into assemblies, and fixes startup failures when no GL context is available. (#1366, #1296, #1328)
