GitHub Actions Runner Images refresh CI

GitHub’s runner-images repository defines the virtual-machine environments powering GitHub Actions and Azure Pipelines, with weekly updates across Ubuntu, Windows, and macOS. Its latest releases update core developer tooling while documenting the coming Ubuntu 26.04 migration. [Repository](https://github.com/actions/runner-images) · [Latest releases](https://github.com/actions/runner-images/releases)

// ANALYSIS

This is unglamorous infrastructure with outsized impact: small image changes can decide whether an entire CI fleet passes or breaks.

–Weekly toolchain refreshes keep compilers, CLIs, runtimes, and package managers current.
–The Ubuntu 26.04 migration makes `-latest` labels a reliability risk for workflows that do not pin OS versions.
–Explicit image labels improve reproducibility and make rollback planning easier.
–Public image definitions give teams a practical baseline for custom self-hosted runners.
–AI developers benefit indirectly through more predictable build, test, packaging, and deployment pipelines.
