GitHub Actions ARM32 support ends on December 8

GitHub-hosted Windows and Linux runners will stop running ARM32 jobs in the AArch32 user space after December 8, 2026.

What is changing?

On December 8, 2026, GitHub Actions will end support for running ARM32-based jobs in the native AArch32 user space on its hosted Windows and Linux runners.

The decision follows GitHub Actions' retirement of Node.js 20. Because the new Node.js 24 runtime does not support ARM32, this execution path is also being retired.

Who should check?

Teams using ARM32 binaries, emulation steps or tools that depend on an AArch32 user space need to review their workflow files and runner choices.

Teams that need to continue ARM32 builds may have to plan for a self-hosted runner or another build infrastructure.
