Aiven for Apache Kafka® 4.2

Apache Kafka® 4.2 is now available on Aiven. You can create new services on Kafka 4.2 or upgrade your existing ones.

Key features:

• Shared groups (Kafka queues): Lets multiple consumers read from the same partition for queue-style, scalable consumption. Shared groups require at least three nodes and aren't available on the free or developer tiers.
• Streams rebalance protocol: Provides centralized rebalancing for Kafka Streams. The protocol is enabled by default on new Kafka 4.2 clusters and is available on all tiers.

This release also includes bug fixes and stability improvements. For details, see the Apache Kafka 4.2.0 release notes.
