 ### Major changes, deprecations and removals
 
+* 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.
