   Once the first three phases are comleted, the release branch enters the final stage. The community prepares for the official release by conducting thorough testing and ensuring documentation and release notes are up-to-date. Following this, the final version is officially released and made available for public use.
 
-When the code base is sufficiently stable, the master branch opens for general development and work begins there for the next release milestone. Any remaining modifications for the current release are cherry picked from master back to the release branch. The release is built from the release branch.

+## Patch Release
+
+Our typical patch release cadence is monthly. If there are critical issues present in the current version, an expedited release may be necessary.
+
+### Cherry Picks
+
+Any remaining modifications for the current release are cherry picked from master back to the release branch. Cherry picks must be merge-ready in GitHub with proper labels (e.g., approved, lgtm, release-note) and passing CI tests ahead of the patch release deadline.
+
+### Support Versions
 
-Each release is part of a broader KubeEdge lifecycle:
+We provide maintenance for the latest three releases. This means that bug fixes will be applied to these releases to ensure their stability and reliability. However, in exceptional cases where severe issues arise, we may consider releasing patches for earlier versions as well, based on the specific circumstances.

+补丁版本通常是每月发布一次，如果出现严重问题需要修复，社区也会缩短发布周期，尽快发布补丁版本。

+通常社区会维护最新三个版本的补丁发布，这意味着问题修复可以合入最新三个版本来保证版本的稳定性与可靠性。如果出现严重问题，社区会根据具体情况考虑对更早的版本发布补丁。
