I'm trying to determine which version of Elasticsearch to use in our deployment.

• The Helm charts currently lists 7.17.9, which appears to be quite outdated.
• The Platform Support Guide indicates that the latest supported version is 8.18.3, released in June.
• On the ElasticSearch site, there are multiple newer versions available: 9.2.1, 9.1.7, 8.19.7, and 8.18.8.

I assume that 9.x, since it's a major version change, hasn't been validated by Pega yet, and likely the same applies to 8.19.x. However, 8.18.8 is a patch release that includes security updates, so it seems like a valid option.

What is Pega’s recommendation for versioning?

• Should we only use the versions listed in the Platform Support Guide?
• Is it acceptable to stay on the latest patch of the recommended minor version (8.18.8)?

Thanks
