Version 2.80.2

Uno, WebAssembly, and GPU diagnostics · Released September 12, 2020 · NuGet · GitHub Release

API changes · SkiaSharp API diff · HarfBuzzSharp 2.6.1.7

Highlights

Version 2.80.2 extends the 2.80 line with broader Uno Platform coverage, better WebAssembly support, and new GPU diagnostics APIs, while also landing important fixes for text, invalidation, native library probing, and pixel handling. It ships with HarfBuzzSharp 2.6.1.7 for the aligned shaping bindings.

Breaking Changes

None in this release.

New Features

Platform

  • Broader Uno Platform support — Adds Uno GPU views, additional Uno-specific work, and WebAssembly support for Uno applications. (#1429, #1420, #1333)
  • Native-only packaging — Introduces a NuGet package that carries only the native assets for scenarios that need a slimmer distribution model. (#1456)

GPU & Rendering

  • GPU diagnostics APIs — Exposes SKGraphics debugging hooks and adds several more GPU debugging members. (#1473, #1478)

API Surface

  • Additional color helpers — Adds extensions for SKColorF and a replacement helper API in the 2.80 line. (#1469, #1431)

Bug Fixes

  • Text and drawing correctness — Fixes invalid-text handling, restores compatible linear metrics behavior, corrects SKCanvas.DrawTextOnPath on iOS, and honors the origin parameter in SKSurface.Create. ❤️ @ziriax (#1438, #1439, #1410, #1404)
  • Platform invalidation and probing — Improves UWP invalidation, switches macOS refreshes to NeedsDisplay, and checks the correct native-library directory for ASP.NET deployments. (#1468, #1475, #1483)
  • Native and pixel fixes — Corrects the WebAssembly + GL native path, ensures pixel writes update the backing store, and reverts problematic SetScaleTranslate behavior. (#1445, #1457, #1452)
