Two new GitHub-hosted runner images for GitHub Actions are now available in public preview for all users, giving you early access to test your workflows on the latest platforms before they reach general availability.

Ubuntu 26.04

The Ubuntu 26.04 image is now available for both x64 and arm64 architectures. To start using it, update your workflow file to use runs-on: ubuntu-26.04 or runs-on: ubuntu-26.04-arm. Ubuntu 26.04 base images are also available for larger runner users.

Some users may notice differences in their workflows as the Ubuntu 26.04 image has different tools and tool versions compared to earlier images. For the full list, head to the runner-images repository.
