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

Refer to the following documentation for the details about the release content, update schemes, and so on:
