15.x series¶
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 your deployment needs, you can either update only between major Cluster releases or apply patch updates between major releases. Choosing the latter option ensures you receive security fixes as soon as they become available. Though, be prepared to update your cluster frequently, approximately once every three 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.
