Highlights

SkiaSharp 2.88.1 adds a substantial new animation story with Skottie, expands WinUI and Tizen support on newer target frameworks, and refreshes several native dependencies. It also fixes a range of real-world issues across Alpine Linux, Unicode font loading, Apple scaling behavior, and browser-hosted scenarios.

Breaking Changes

Skottie and SceneGraph moved out of the core assembly — Applications using those APIs should make sure the matching packages are referenced explicitly instead of expecting everything to ship in SkiaSharp.dll. (#2091)

New Features

Animation & Text

Basic Skottie support — Introduces the first Skottie bindings, then rounds them out with nullable annotations, TimeSpan overloads, writable SKDataStream, and support for non-seekable streams. ❤️ @jeromelaban (#1987, #2119, #2128, #2126)
Better text shaping controls — SKShaper now respects SKPaint.TextAlign. ❤️ @koolkdev (#1910)
AVIF encode support — Exposes AVIF as an image encode format. ❤️ @mgood7123 (#2154)

Platform

WinUI and Uno support — Adds WinUI support and keeps Uno generation aligned on supported targets, with follow-up generation fixes for Xamarin targets. (#2042, #2098, #2199)
More modern target frameworks — Adds net6.0-tizen and expands Skottie package TFMs across Apple, Android, tvOS, Mac Catalyst, and Tizen. (#2099, #2133)
Updated WebAssembly toolchain — Adds emscripten 3.1.7 support. ❤️ @jeromelaban (#2094)

Bug Fixes

Unicode font names load correctly — Fixes font loading when the font name contains Unicode characters. ❤️ @lindexi (#2146)
Apple view scaling updates — Reshapes SKGLView correctly when Window.BackingScaleFactor changes. ❤️ @HarlanHugh (#1854)
Alpine and libc loading reliability — Fixes Alpine builds and prefers the full libc library name where required. (#2168, #2192, #2213)
Safer native lock cleanup — Checks whether the lock has already been finalized before entering or leaving the critical section. ❤️ @RichardD2 (#2195)
Animation and imaging fixes — Adds BOM handling for animation loading and fixes PNG loading by updating zlib. (#2167, #2045)

Native Dependencies

Refreshed native libraries — Updates zlib, libjpeg-turbo, libwebp, and libexpat to newer servicing releases. (#2045, #2206, #2193, #2189)
