 ### Removal of v1alpha3 & v1alpha4 apiVersions
 
-We are going to remove the apiVersions in upcoming releases:
-* v1.5:
-  * Kubernetes API server stops serving the v1alpha3 apiVersion
-* v1.6:
-  * v1alpha3 apiVersion is removed from the CRDs
-  * Kubernetes API server stops serving the v1alpha4 apiVersion
-* v1.7
-  * v1alpha4 apiVersion is removed from the CRDs
+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).
 
 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)
