Release Notes

strimzi/strimzi-kafka-operator (strimzi/strimzi-kafka-operator)

v0.51.0

Compare Source

• Add support for Kafka 4.2.0 and remove support for Kafka 4.0.0 and 4.0.1
• Allow setting the following configurations with the listener prefix (e.g. listener.name.listener1-9900.): connections.max.reauth.ms, max.connections* and max.connection.creation.rate.
• The ServerSideApplyPhase1 feature gate moves to beta stage and is enabled by default.
  If needed, ServerSideApplyPhase1 can be disabled in the feature gates configuration in the Cluster Operator.
• Fixed auto-rebalancing on scale up not running anymore when Cruise Control is not ready yet on the first attempt.

Major changes, deprecations, and removals

• From Strimzi 0.51 on, we support only Kubernetes 1.30 and newer.
  Kubernetes 1.27, 1.28, and 1.29 are not supported anymore.
• The ingress listener type is deprecated due to the archiving of the Ingress NGINX Controller for Kubernetes (March 2026).
  The code remains in the Strimzi codebase, but no further improvements or development are planned.
