OpenSearch admins must understand what index versions are compatable with which OpenSearch versions. Previously, this page https://docs.opensearch.org/latest/upgrade-or-migrate/#index-compatibility-reference , provided a source of truth for this info.

However, the page does not provide any info beyond OpenSearch 2.14 when the latest version is 3.5.0.

Version: List the OpenSearch version to which this issue applies, e.g. 2.14, 2.12--2.14, or all.

What other resources are available? Provide links to related issues, POCs, steps for testing, etc.

In case this is helpful, i've updated my local copy of this info by verifying with the different tags from

• Opensearch:
  • https://github.com/opensearch-project/OpenSearch/blob/main/gradle/libs.versions.toml
• Elasticsearch:
  • https://github.com/elastic/elasticsearch/blob/main/build-tools-internal/version.properties
