MSYS2 now ships GCC 16 with native Thread Local Storage (TLS) enabled, replacing the old emulated variant (emutls). Some CPython micro benchmarks run 3x faster as a result. Full details: www. msys2.org/news/#2026-05-11-native-thread-local-storage-tls-with-gcc-16

Good news: Thanks to the 'Git for Windows' team, we now have native Git packages in our repository, which should provide a similar experience to the official Git builds. Less battle tested and integrated, but please give it a try and let us know of any issues. www.msys2.org/news/#2026-0...

Some deprecations: We no longer support Windows 8.1. It's EOL for 3 years now, and with Firefox dropping support too, now is a good time to say farewell. Things will not stop immediately, but no guarantees.

With us moving to the new hosted ARM64 runners, a look back at our self-hosted ARM64 runner journey: www.msys2.org/news/#2025-0...

GitHub Actions dashboard showing 100,031 total minutes and 6,003 job runs over the past year. The main workflow "build.yml" used 95,577 minutes across 1,835 runs on a self-hosted Windows runner.

MSYS2 @msys2org.bsky.social · 16/04/2025

Native Windows ARM64 runners are now available on GitHub Actions. Just use "runs-on: windows-11-arm" and the setup-msys2 action with "msystem: CLANGARM64" to start building/testing. >90% of MSYS2 packages are available for ARM64, so everything should be good to go.
