We are pleased to announce the second milestone release of Spring for Apache Kafka 4.0.x generation - 4.0.0-M2, which now supports Apache Kafka 4.0.0.

Key Changes in 4.0.0-M2

• The Kafka client in 4.0.0-M2 has been updated to 4.0.0
• All ZooKeeper related support is now dropped from the 4.0.0-M2, since Apache Kafka 4.0.0 has completely removed ZooKeeper dependency and now exclusively uses KRaft for leadership election and quorum management
• The EmbeddedKafkaBroker utility that Spring for Apache Kafka provides for testing purposes will no longer work with ZooKeeper, as it only supports the KRaft protocol
• We also verified that the next generation consumer rebalance protocol introduced via KIP-848 works seamlessly via Spring for Apache Kafka 4.0.0-M2
