doc/release-notes/rl-2505.section.md

···
 
 - Default ICU version updated from 74 to 76
 
+- Apache Kafka was updated to `>= 4.0.0`. Please note that this is the first release which operates
+  entirely without Apache ZooKeeper support, and all clusters need to be migrated to KRaft mode. See
+  the [release announcement](https://kafka.apache.org/blog#apache_kafka_400_release_announcement)
+  for more details.
