+* SSE-C in S3 security mapping for Delta Lake, Hive, Hudi, and Iceberg
+* Allow configuration for Google Cloud Storage endpoint with object storage
+  connectors.
+* Allow connection validation and add more stats for JDBC driver. 
+* Remove support for connector-level event listeners.
+* Misc improvements for the Faker connector.
+
+As always, numerous performance improvements, bug fixes, and other features were
+added as well.
