Highlights

SkiaSharp 1.68.1 ships the long-running 1.68.1 line as stable with a broad wave of API, view and HarfBuzz work. This is a large servicing release built from six release candidates over four months. It expands the managed API with Span-based buffers, an SKPictureShader binding and new SKTypeface members, reworks the managed/native type layer for stability, splits the desktop view packages, and refreshes HarfBuzzSharp to 2.6.1.

Breaking Changes

None in this release.

API Surface

Span-based data, bitmap and text APIs — Adds Span<T> overloads for data buffers, bitmap pixels and text blobs so callers can hand SkiaSharp existing memory without copying through byte arrays. (#865)
SKPictureShader and typeface additions — Binds SkPictureShader for tiling and transforming recorded pictures, adds SKTypeface.IsFixedPitch, and lands int-unicode overloads for consistency across the text APIs. — ❤️ @alexandrvslv, @Gillibald (#973, #1019, #972)
Managed/native type layer reworked — Reworks how managed wrappers own and reference native objects so shared instances such as colour spaces stop being disposed out from under callers. (#900, #922)
HarfBuzzSharp font funcs and table loading — Adds font-funcs bindings on the HarfBuzzSharp side and lets faces be loaded directly from table data, alongside general HarfBuzz binding polish. — ❤️ @Gillibald (#881, #862, #915)

Bug Fixes

iOS canvas and raster view corrections — Fixes the iOS canvas implementation and stops raster views allocating zero-byte buffers when the surface has no size yet. — ❤️ @Odirb (#879, #761, #863)
Memory and stability fixes — Frees native memory when a view is detached, plugs an SKRoundRect leak, and improves UWP GPU view stability under teardown. (#1005, #995, #1024, #1023, #1000)

Platform

Desktop view packages split; WPF Forms backend added — Splits the desktop view projects and NuGet packages so consumers can pull only the framework they need, and adds a WPF backend for Xamarin.Forms. (#899, #917)
watchOS and tvOS bitcode, arm64_32 for watchOS — Enables bitcode for watchOS and tvOS and adds the watchOS arm64_32 slice so SkiaSharp keeps working on modern Apple wearables. (#971, #967)
Optional fontconfig on Linux — Lets SkiaSharp be built without fontconfig for stripped-down Linux containers and images that do not ship the library. (#821)

HarfBuzzSharp 2.6.1

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