2. They can be checked as done once they land in master.
3. They are presented here for quick reference, but backporting is tracked in each Release Checklist.

✅ Release Checklist

⬅️ Before RC1

Section

• Open PR against RELEASE_ISSUE_TEMPLATE.md with title docs(release): v1.31.1 release template improvements for improving future releases.
  • Link to PR: docs(release): v1.30.0, v1.31.0 and v1.31.1 release template improvements #12563
  • There likely aren't any changes at this point, but this can be opened with a small whitespace change so the PR is open and we can more easily hold the standard of making improvements incrementally since improvements are usually better done by collecting changes/notes along the way rather than just thinking about it at the end.
  • This will get merged in a Post Release step.
• Fork a new release/v1.31.1 branch from the master branch and make any further release-related changes to this branch.
  • Note: For critical security patches, fork a new branch from the last stable release/vX.Y.x to expedite the release process.
