 ### Removal of v1alpha3 & v1alpha4 apiVersions
 
-Both v1alpha3 and v1alpha4 have been removed from Cluster API as of release 1.7.
-
-For more details and latest information please see the following issue: [Removing v1alpha3 & v1alpha4 apiVersions](https://github.com/kubernetes-sigs/cluster-api/issues/8038).
+Cluster API stopped to serve v1alpha3 API types from the v1.5 release and v1alpha4 types starting from the v1.6 release.
+Those types still exist in Cluster API while we work to a fix (or a workaround) for https://github.com/kubernetes-sigs/cluster-api/issues/10051.
+IMPORTANT! v1alpha3 and v1alpha4 types only exist for conversion and cannot be used by clients anymore.
 
 Note: Removal of a deprecated APIVersion in Kubernetes [can cause issues with garbage collection by the kube-controller-manager](https://github.com/kubernetes/kubernetes/issues/102641)
 This means that some objects which rely on garbage collection for cleanup - e.g. MachineSets and their descendent objects, like Machines and InfrastructureMachines, may not be cleaned up properly if those
