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 0.24 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 0.24 is done!

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

Changes, deprecations and removals

• The deprecated KafkaConnectS2I custom resource will be removed after the 0.24.0 release.
  Please use the migration guide to migrate your KafkaConnectS2I deployments to KafkaConnect Build instead.
• The fields topicsBlacklistPattern and groupsBlacklistPattern in the KafkaMirrorMaker2 resource are deprecated and will be removed in the future.
  They are replaced by new fields topicsExcludePattern and groupsExcludePattern.
• The field whitelist in the KafkaMirrorMaker resource is deprecated and will be removed in the future.
  It is replaced with a new field include.
• bind-utils removed from containers to improve security posture.
• Kafka Connect Build now uses hashes to name downloaded artifact files. Previously, it was using the last segment of the download URL.
  If your artifact requires a specific name, you can use the new type: other artifact and its fileName field.
• The option enableECDSA of Kafka CR authentication of type oauth has been deprecated and is ignored.
  ECDSA token signature support is now always enabled without the need for Strimzi Cluster Operator installing the BouncyCastle JCE crypto provider.
  BouncyCastle library is no longer packaged with Strimzi Kafka images.
