This patch updates Splat's Primitives dependency, ReactiveUI.Disposables, from 9.0.0 to 10.0.0. It aligns Splat with the latest Primitives release without changing Splat's public API or supported target frameworks.

💖 Thanks to all the contributors: @glennawatson

Splat 22.0.0 adds direct memory image decoding and removes the .NET 8, .NET 9, and .NET Framework 4.6.2 (net462) targets. This is a major release because applications targeting those frameworks must retarget before upgrading.

New image decoding APIs

Splat.SkiaSharp adds SkiaBitmapLoader.LoadFromMemory overloads for decoding encoded image data from ReadOnlyMemory<byte>. Applications that already hold image bytes can pass them directly without wrapping them in a stream. The overloads support requested image dimensions and apply the image's recorded orientation.

An overload accepts a CancellationToken. Cancellation is checked between native image operations; an operation already in progress cannot be interrupted. These APIs are available on both .NET 10 and .NET 11. See the implementation and public API additions.

The .NET 11 assemblies also keep Runtime Async disabled to preserve compatibility with consumers running on Blazor WebAssembly.

.NET 8 and .NET 9 removal

.NET 8 and .NET 9 both reached Microsoft's end of support on 10 November 2026. Microsoft no longer provides security fixes, servicing updates, or technical support for either version. Splat now targets .NET 10 and .NET 11 for modern .NET applications. See Microsoft's .NET 8 and .NET 9 end-of-support announcement and the .NET support policy.

.NET Framework 4.6.2 (net462) removal

Microsoft lists the end of support for .NET Framework 4.6.2 as 12 January 2027. We are removing this target ahead of that deadline as part of the same compatibility change. This reduces the legacy build and dependency combinations we maintain. Other .NET Framework targets remain: packages that provide .NET Framework assets retain targets from net47 through net481. See Microsoft's .NET Framework support policy.

Upgrading

Retarget .NET 8 or .NET 9 applications to .NET 10 LTS or .NET 11, including the matching platform target for UI applications. For .NET Framework applications, prefer 4.8 or 4.8.1 where supported by your Windows version. Available targets vary by package and UI platform.

If you cannot retarget yet, keep using a compatible Splat 21.x version while planning the migration. Staying on an older package does not extend Microsoft's runtime support. Removing these targets lets us focus maintenance and dependency updates on the remaining framework combinations.

🔏 19.4.1 — consolidated, re-signed release

This is the recommended release. It supersedes and folds in 19.3.1, which was signed with a code-signing certificate that has since been revoked — NuGet restore fails on it with NU3012. 19.4.1 is re-signed with a valid certificate; the superseded 19.3.1 release has been removed and its notes consolidated here.
