-Most clients that work with Elasticsearch OSS 7.10.2 *should* work with OpenSearch, but the latest versions of those clients might include license or version checks that artificially break compatibility.

+Clients that work with Elasticsearch OSS 7.10.2 should work with OpenSearch 1.x. The latest versions of those clients, however, might include license or version checks that artificially break compatibility. The following table provides recommendations for which client versions to use for best compatibility with OpenSearch 1.x. For OpenSearch 2.0 and later, no Elasticsearch clients are fully compatible with OpenSearch.
+
+While OpenSearch and Elasticsearch share several core features, mixing and matching the client and server has a high risk of errors and unexpected results. As OpenSearch and Elasticsearch continue to diverge, such risks may increase. Although your Elasticsearch client may continue working with your OpenSearch cluster, using OpenSearch clients for OpenSearch clusters is recommended.
