Hey Luke, Thank you for the review! My reasoning for going to ZK 3.8.1 directly is that if there isn’t a set date for the Kafka 4.0 release it gives us more time before we have to (potentially) upgrade ZK again (similar to what is mentioned here https://github.com/apache/kafka/pull/12620#issuecomment-1245590870). ZK 3.7.1 also doesn’t support earlier client/server combinations different to what 3.8.1 does.
