- This overstates truncated-run support and omits one shipped merge engine. RFC 018 explicitly says the capability accepts an incomplete set of complete artifacts and does not recover partially written or malformed output; the built-in TRX processor also opts out. PR #9805 added JUnit alongside TRX and CTRF. Please describe the opt-in truncated-run capability precisely and include JUnit.
* Add artifact post-processing for `dotnet test`, including TRX and CTRF merge engines, artifact-kind metadata, partial-output recovery for truncated runs and provenance for every merged input, by @Evangelink in [#9805](https://github.com/microsoft/testfx/pull/9805), [#10086](https://github.com/microsoft/testfx/pull/10086), [#10445](https://github.com/microsoft/testfx/pull/10445) and [#10463](https://github.com/microsoft/testfx/pull/10463)

The unreleased MSTest 4.4 and Microsoft.Testing.Platform 2.4 changelogs omitted several important user-facing changes that landed during the release cycle.
This update fills those gaps across new public APIs and analyzers, WebAssembly and WinUI support, artifact post-processing, reporting and telemetry improvements, retry behavior, and notable reliability fixes. It also removes the now-stale Azure DevOps retry caveat after retry attempts became sub-results and adds missing attribution to the pipeline-reference entry.
