Ubuntu 26.04 runner image generally available on GitHub Actions
GitHub has announced the general availability of the Ubuntu 26.04 runner image for GitHub Actions on both x64 and arm64 architectures. The ubuntu-latest label will gradually migrate from Ubuntu 24.04 to Ubuntu 26.04 between October 19 and November 19, 2026. Workflows requiring older environments can be pinned to ubuntu-24.04 to avoid breaking changes caused by updated or removed tools.
