Backporting

This document explains how to backport a merged PR from master to one of the stable* branches. Backports should only be used to fix bugs or security issues - never to introduce new features.

Steps

1. Fix a bug through a PR that targets master.
2. Add label A4-needs-backport to the PR.
3. Merge the PR into master.

5. Ensure the change is audited or does not need audit.
6. Merge the backport PR.
