CRD Upgrades

!!! IMPORTANT !!!

This release supports only the API version v1beta2 and CRD version apiextensions.k8s.io/v1. If upgrading from Strimzi 0.22, migration to v1beta2 needs to be completed for all Strimzi CRDs and CRs before the upgrade to 0.26 is done! If upgrading from Strimzi version earlier than 0.22, you need to first install the CRDs from Strimzi 0.22 and complete the migration to v1beta2 for all Strimzi CRDs and CRs before the upgrade to 0.26 is done!

For more details about the CRD upgrades, see the documentation.

Changes, deprecations and removals

• imageRepositoryOverride, imageRegistryOverride and imageTagOverride are now removed from values.yaml in the Helm Chart. defaultImageRepository, defaultImageRegistry and defaultImageTag values are introduced in Helm Charts which sets the default registry, repository and tags for the images.
• The OpenShift Templates were removed from the examples and are no longer supported (#5548)
• Kafka MirrorMaker 1 has been deprecated in Apache Kafka 3.0.0 and will be removed in Apache Kafka 4.0.0. As a result, the KafkaMirrorMaker custom resource which is used to deploy Kafka MirrorMaker 1 has been deprecated in Strimzi as well. The KafkaMirrorMaker resource will be removed from Strimzi when we adopt Apache Kafka 4.0.0. As a replacement, use the KafkaMirrorMaker2 custom resource with the IdentityReplicationPolicy.
