+
+Are you using the [kroxylicuous-junit5-extension](https://github.com/kroxylicious/kroxylicious-junit5-extension) to inject Kafka clusters into your integration tests?   With Apache Kafka approaching the 4.0 milestone, we
+are looking for input to help decide the best way to manage the move to Kafka 4.0.
+
+Kafka 4.0 will will remove support for Zookeeper managed clusters.  The Extension is currently capable of producing clusters managed by KRaft or Zookeeper, using
+whatever Kafka version you provide to it on the classpath.  With Kafka 4.0's arrival the possibility of a Zookeeper managed cluster goes away.
+
+How important it is to you that the Extension continues to support the production of Kafka clusters managed by Zookeper when _Kafka 3.x_ is on the classpath?  Talk to us on this issue [#389](https://github.com/kroxylicious/kroxylicious-junit5-extension/issues/389).
