+== New features and improvements
+
+=== Debezium for Oracle
+
+==== Support for Oracle 26ai
+
+The Debezium connector for Oracle now supports Oracle's latest release, Oracle 26ai, based on version 23.26.0 (https://github.com/debezium/dbz/issues/1649[debezium/dbz#1649]).
+This ensures that teams adopting Oracle's newest platform can seamlessly integrate change data capture into their workflows from day one.
+As Oracle continues to evolve its database offerings, Debezium remains committed to keeping pace with the latest innovations.
