-----------------------------------
Summary: Remove no longer required server protocol versions in
Kafka 4.0
Key: KAFKA-14552
URL: https://issues.apache.org/jira/browse/KAFKA-14552
Project: Kafka
Issue Type: Improvement
Reporter: Ismael Juma
Fix For: 4.0.0
Kafka 4.0 will remove support for zk mode and kraft mode became production
ready in Kafka 3.3. Furthermore, migration from zk mode to kraft mode will
require upgrading to the bridge release first (likely 3.5, but could also be
3.6).
This provides an opportunity to remove exclusively server side protocols
versions that only exist to allow direct upgrades from versions older than 3.n
where n is either 0 (KRaft preview), 3 (KRaft production ready) or 5 (bridge
release). We should decide on the right `n`.
