The SDK's GZipCompress task moves to multithreaded execution while macOS templates get AOT deduplication and a critical strip command fix that was crashing apps at launch.

The dotnet/sdk team completed a critical migration of the GZipCompress MSBuild task to multithreaded execution [1], fixing a dependency on shared process working directories that breaks under parallel builds. This follows the broader push to make all MSBuild tasks thread-safe and is part of fixing dotnet/msbuild#14166. Over in dotnet/macios, two production fixes landed: an AOT generic instantiation deduplication improvement [6] that activates when PrepareAssemblies=true, and more critically, a fix [7] for app crashes at launch when _ExportSymbolsExplicitly=false that was stripping symbols the runtime needs. Separately, dotnet/macios also resolved a race condition [8] where debugging environment variables were being read and unset on a background thread instead of main, creating timing-dependent behavior for managed apps. The dotnet/skills repo consolidated duplicate test framework documentation [9] and bumped the dotnet-test plugin to 0.2.0 [10], while also raising eval timeouts [11] for scenarios that were chronically hitting wall-clock limits. Codeflow updates continue flowing from source-build-assets [2], arcade [3], runtime [4], and sdk [5] into the main dotnet repo.
