This guide explains how to perform a patch level update. The patch level is the version number “after the second dot”. Example: update from 3.15.2 to 3.15.3.

Special Considerations

This section describes noteworthy changes between individual patch levels.

3.15.2 to 3.15.3

Changes in supported Elasticsearch versions

With 3.15.3, Optimize is dropping support for Elasticsearch 8.13, 8.14 and 8.15. Optimize now supports 8.16 and 8.17. If you are on a lower version of Elasticsearch, you will have to update your Elasticsearch instance before executing the Optimize migration.
