breaking patch
The Ubuntu 26.04 runner image for GitHub Actions is now generally available for production workflows on both x64 and arm64, moving out of public preview. This release ensures GitHub Actions users have access to the latest Ubuntu version, impacting workflows by updating or removing preinstalled tools and packages. The `ubuntu-latest` label will gradually migrate to Ubuntu 26.04 between October 19 and November 19, 2026. Users should test their workflows against Ubuntu 26.04 before this migration or pin to `ubuntu-24.04` if not ready, as compatibility issues may arise.
