0.44.0
7e49e5f

⚠️ Important: Strimzi 0.44 supports only Kubernetes 1.25 and newer. Kubernetes 1.23 and 1.24 are not supported anymore.

Main changes since 0.43.0

This release contains the following new features and improvements:

  • Add the "Unmanaged" KafkaTopic status update.
  • The ContinueReconciliationOnManualRollingUpdateFailure feature gate moves to beta stage and is enabled by default.
    If needed, ContinueReconciliationOnManualRollingUpdateFailure can be disabled in the feature gates configuration in the Cluster Operator.
  • Add support for managing connector offsets via KafkaConnector and KafkaMirrorMaker2 custom resources.
  • Add support for templating host and advertisedHost fields in listener configuration.
  • Allow configuration of environment variables based on Config Map or Secret for every container in the container template sections.
  • Add support for disabling the generation of PodDisruptionBudget resources by the Cluster Operator.
  • Add support for running an automatic rebalancing, via Cruise Control, when the cluster is scaled down or up:
    • after a scaling up, the operator triggers an auto-rebalancing for moving some of the existing partitions to the newly added brokers.
    • before scaling down, and if the brokers to remove are hosting partitions, the operator triggers an auto-rebalancing to these partitions off the brokers to make them free to be removed.
  • Strimzi Access Operator 0.1.0 added to the installation files and examples

All changes can be found under the 0.44.0 milestone.

Watch out also for some notable changes, deprecations, and removals:

  • When finalizers are enabled (default), the Topic Operator will no longer restore finalizers on unmanaged KafkaTopic resources if they are removed, aligning the behavior with paused topics, where finalizers are also not restored.
    This change matches user expectations.
  • The External Configuration (.spec.externalConfiguration) in KafkaConnect and KafkaMirrorMaker2 resources is deprecated and will be removed in the future.
    Please use the environment variables, additional volumes and volume mounts in Pod and container templates instead.
  • The Strimzi Canary installation files were removed based on the Strimzi proposal 086 as the project was discontinued and archived.

Upgrading from Strimzi 0.43.0

See the documentation for upgrade instructions.

Upgrading from Strimzi 0.22 or earlier

Direct upgrade from Strimzi 0.22 or earlier is not supported anymore! You have to upgrade first to one of the previous versions of Strimzi. You will also need to convert the CRD resources. For more details, see the documentation.
