Feature parity/differences with elasticsearch 7.10.2

As the opensearch suite is derived from Elasticsearch (& kibana) 7.10.2, I would like to understand the feature parity between opensearch (archive/rpm etc) with elasticsearch-oss and opensearch-dashboard (archive/rpm etc) with kibana-oss respectively.

Leaving aside the additional functionalities provided by the opensearch plugins, is there a document that lists the changes done in opensearch from elastic oss 7.10.2?
For ex. trademark changes, vulnerability fixes etc…

It would be great if that can also be documented in the release-notes.


A good place to start to understand the changes that have been made is this post… Preparing OpenSearch and OpenSearch Dashboards for release
