+# OpenSearch and Dashboards 2.1.0 Release Notes
+
+## Release Highlights
+
+
+* OpenSearch 2.1.0 supports version spoofing against 2.0.0 where it was [removed](https://github.com/opensearch-project/opensearch/pull/3530).

+* SQL and PPL queries now supports [relevance-based search](https://github.com/opensearch-project/sql/issues/182), including [match_function](https://github.com/opensearch-project/sql/pull/204], [match_phrase](https://github.com/opensearch-project/sql/pull/604), and [match_bool_prefix](https://github.com/opensearch-project/sql/pull/634).
