1. This is the set of changes that need to make it in for a given RC. This is effectively the set of changes to cherry-pick from master.
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.

rc1

• fix: fr32: Correct multithreaded Unpad chunk boundary alignment and simplify unpadReader #13455

Stable Release (non-RC)

• fix(eth): fix eth_syncing result property casing & implement UnmarshalJSON for EthSyncingResult #13484

✅ Release Checklist

⬅️ Before RC1

Section

• Open PR against RELEASE_ISSUE_TEMPLATE.md with title docs(release): v1.34.4 release template improvements for improving future releases.
  • Link to PR: docs(release): v1.34.2 release template improvements #13399
  • 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/v1.34.4 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.
• Fork a new release/miner/v1.34.4 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.
