🔥 Hot Topics

Breaking changes being planned for v4.3/MTP 2.3

Two fresh breaking-change proposals landed today — good time for the team to weigh in:

• #7665 — [Breaking] Don't set IsTestingPlatformApplication by MTP — would fix a long-standing friction where MSTest/NUnit can't respect user-specified values.
• #7664 — [Breaking] Change default of --show-stdout/--show-stderr to failed — aligns output defaults with typical CI expectations.

stdout/stderr story evolving 📺

After reverting the fully-silent approach, the team now has opt-in --show-stdout/--show-stderr flags. Issue #7647 proposes complementary TESTINGPLATFORM_NOPROGRESS / TESTINGPLATFORM_NOANSI env vars — a great DX win especially for Copilot/LLM tooling.

CI infrastructure cleanup ✅

Deprecated Arcade options (enablePublishBuildArtifacts, enablePublishBuildAssets) were replaced with the modern artifacts schema. Pipeline is cleaner now!

📊 Project Status

Area	Status

✅ Recommended Next Steps

1. Review breaking-change proposals #7665 and #7664 — early alignment avoids rework.
2. Merge quick wins: #7597 (Polyfill removal) and #7568 (no integration tests in release) look ripe.
3. Discuss #7647 — env var controls for ANSI/progress complement the just-landed --show-stdout/--show-stderr flags nicely.
4. Assert.Scope() (#7355) — a high-value feature; bump its review priority for v4.3.
5. Close the loop on SIGTERM (#2035) — long-standing issue that aligns well with MTP's graceful shutdown story.
