GitHub Actions to retire ARM32 hosted runner support on Linux and Windows by December 8, 2026
GitHub announced that GitHub Actions hosted runners will end support for ARM32 job execution on Windows and Linux by December 8, 2026. The change follows GitHub's earlier end of support for Node 20.
Why it matters
Workflows that run jobs on ARM32 hosted runners for Windows or Linux will stop executing after the deadline and will need to be moved to a supported runner architecture before then.
Who should care
Teams and open-source maintainers using GitHub Actions hosted runners for ARM32 builds or tests on Linux or Windows, and developers maintaining CI/CD pipelines.
What you can do
Audit your workflow files for ARM32 runner labels on Linux and Windows and migrate those jobs to a supported runner type before December 8, 2026.
