I am using opendistro/elasticsearch 7.10.2. and there is not any version change.

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance.

As the bot says: you're using something that isn't really Elasticsearch, it's a different product, so will need to look elsewhere to find the help you need.
