This section outlines release notes for unsupported Cluster releases of the 15.x series.
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 Cluster releases, or update between the major Cluster releases receiving the patch updates in between.
Select 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 two weeks. Otherwise, you can update only between major Cluster releases as each subsequent major Cluster release includes patch Cluster release updates of the previous major Cluster release.
