On behalf of the team and everyone who contributed, we are pleased to announce that Spring for Apache Kafka 4.0.0-M3 has been released.

We extend our gratitude to all contributors who made these releases possible.

4.0.0-M3 provides initial support for Kafka queues (Share consumers) introduced via KIP-932 in Apache Kafka 4.0.0. Keep in mind that in Apache Kafka 4.0.0, queue support is introduced as an early access feature, and as such, the support that Spring for Apache Kafka provides for this should be considered early access and experimental as well.

You can find more details about it in the reference documentation for Spring for Apache Kafka 4.0.0-M3…

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
