Summary
The runner-images update makes Ubuntu 26.04 and Ubuntu 26.04 Arm available as public previews and adds PostgreSQL to Ubuntu Arm64 images. It also updates tools including Docker Buildx, Rust, GitHub CLI and cloud CLIs, while setting a deprecation path for Ubuntu 22-based images.
Why it matters
CI maintainers can begin architecture and operating-system compatibility testing, but should account for changing preinstalled tool versions and the Ubuntu 22 migration deadline.
