Release Notes

Major and patch versions update path

The primary distinction between major and patch product versions lies in the fact that major release versions introduce new functionalities, whereas patch release versions predominantly offer minor product enhancements, mostly CVE resolutions for your clusters.

Depending on the needs of your deployment, you can either update between only major releases, or update between the major releases receiving the patch updates in between. Choose the second option, which includes patch updates, only if you want to receive security fixes as soon as they become available and you are prepared to update your cluster often, approximately once in three weeks.
