⚠️ Important: Strimzi 0.45 supports only Kubernetes 1.25 and newer. Kubernetes 1.23 and 1.24 are not supported anymore.

Main changes since 0.44.0

This release contains the following new features and improvements:

• Add support for Kafka 3.9.0 and 3.8.1. Remove support for Kafka 3.7.0 and 3.7.1
• Ability to move data between JBOD disks using Cruise Control.
• Allow using custom certificates for communication with container registry in Kafka Connect Build with Kaniko
• Only roll pods once for ClientsCa cert renewal. This change also means the restart reason ClientCaCertKeyReplaced is removed and either CaCertRenewed or CaCertHasOldGeneration will be used.
• Allow rolling update for new cluster CA trust (during Cluster CA key replacement) to continue where it left off before interruption without rolling all pods again.
• Update HTTP bridge to 0.31.1
• Add support for mounting CSI volumes using the template sections

All changes can be found under the 0.45.0 milestone.

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

• Strimzi 0.45 is the last minor Strimzi version with support for ZooKeeper-based Apache Kafka clusters and MirrorMaker 1 deployments. Please make sure to migrate to KRaft and MirrorMaker 2 before upgrading to Strimzi 0.46 or newer.
• Strimzi 0.45 is the last Strimzi version to include the Strimzi EnvVar Configuration Provider (deprecated in Strimzi 0.38.0) and Strimzi MirrorMaker 2 Extensions (deprecated in Strimzi 0.28.0). Please use the Apache Kafka EnvVarConfigProvider and Identity Replication Policy instead.

Upgrading from Strimzi 0.44.0

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.
