Strimzi Kafka Operators 0.46.0 has been released. The main changes in this release include: * Add support for Kafka 4.0.0. Remove support for Kafka 3.8.0 and 3.8.1. * Support for ZooKeeper-based Apache Kafka clusters and for KRaft migration has been removed * Support for MirrorMaker 1 has been removed * Support for storage class overrides has been removed * Added support to configure `dnsPolicy` and `dnsConfig` using the `template` sections. * Store Kafka node certificates in separate Secrets, one Secret per pod. * Allow configuring `ssl.principal.mapping.rules` and custom trusted CAs in Kafka brokers with `type: custom` authentication * Moved HTTP bridge configuration to the ConfigMap setup by the operator. * Dependency updates (Vert.x 4.5.14, Netty 4.1.118.Final) * Moved Kafka Connect configuration to the ConfigMap created by the operator. * Update Kafka Exporter to [1.9.0](https://github.com/danielqsj/kafka_exporter/releases/tag/v1.9.0) * Adopted new Kafka Connect health check endpoint (see [proposal 89](https://github.com/strimzi/proposals/blob/main/089-adopt-connect-health-endpoint.md)). * Update standalone User Operator to handle Cluster CA cert Secret being missing when TLS is not needed. * Strimzi Drain Cleaner updated to 1.3.0 (included in the Strimzi installation files) * Implicit IPv4 preference when enabling JMX has been removed, and will now use JVM defaults. This will make the cluster boot up correctly in IPv6 only environments, where IPv4 preference will break it due to lack of IPv4 addresses. * Improved the MirrorMaker2 example Grafana dashboard to set metric units and include chart descriptions. * The `ContinueReconciliationOnManualRollingUpdateFailure` feature gate moves to GA stage and is permanently enabled without the possibility to disable it. * Update OAuth library to 0.16.2. * Update HTTP bridge to 0.32.0. * Kubernetes events emitted during a Pod restart updated to have the Kafka resource as the `regardingObject` and the Pod in the `related` field. Major changes, deprecations and removals * Support for ZooKeeper-based clusters and for migration from ZooKeeper-based clusters to KRaft has been removed. Please make sure all your clusters are using KRaft before upgrading to Strimzi 0.46.0 or newer! * Support for MirrorMaker 1 has been removed. Please make sure to migrate to MirrorMaker 2 before upgrading to Strimzi 0.46 or newer. * [Strimzi EnvVar Configuration Provider](https://github.com/strimzi/kafka-env-var-config-provider) (deprecated in Strimzi 0.38.0) and [Strimzi MirrorMaker 2 Extensions](https://github.com/strimzi/mirror-maker-2-extensions) (deprecated in Strimzi 0.28.0) plugins were removed from Strimzi container images. Please use the Apache Kafka [EnvVarConfigProvider](https://github.com/strimzi/kafka-env-var-config-provider?tab=readme-ov-file#deprecation-notice) and [Identity Replication Policy](https://github.com/strimzi/mirror-maker-2-extensions?tab=readme-ov-file#identity-replication-policy) instead. * When using Kafka Connect or Kafka MirrorMaker 2 operands and upgrading from Strimzi 0.38 or older, make sure the `StableConnectIdentities` feature gate is enabled and `StrimziPodSets` are used before upgrading. * When using the Kafka operand and upgrading from Strimzi 0.34 or older, make sure the `UseStrimziPodSets` feature gate is enabled and `StrimziPodSet` resources are used before upgrading. * The storage overrides for configuring per-broker storage class are not supported anymore. If you are using the storage overrides, you should instead use multiple KafkaNodePool resources with a different storage class each. For more details about migrating from storage overrides, please follow the [documentation](https://strimzi.io/docs/operators/0.45.0/full/deploying.html#con-config-storage-zookeeper-str). * The Open Policy Agent authorization (`type: opa`) has been deprecated and will be removed in the future. To use the Open Policy Agent authorizer, you can use the `type: custom` authorization. * Removed the `statefulset.kubernetes.io/pod-name` label from pods and external listeners Kubernete
