GitHub Release notes and new features

Control GitHub Actions cache access with cache-mode

You can now use cache-mode to apply least-privilege access to the GitHub Actions cache at the workflow or job level. By granting each workflow or job only the cache access it needs, you can prevent unnecessary restores or saves and help protect trusted workflows from cache poisoning. This capability is now generally available on all plans.
