We should start testing the latest version of Open Search in time before the 6.2 release, as that will be our next opportunity to deliver a more recent version.
OpenSearch 2.19 is scheduled for end of January/middle of February (https://opensearch.org/releases.html), so we should decide whether that is enough time before GA to validate the version.
2.18 is already out and would be the alternative, we might have to start validating it anyways.
