+### GKE Hub Register & Unregister behaviour has changed
+
+The [Hub submodule](https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/tree/master/modules/hub) now supports registering a cluster to a Hub that is in a separate project. This is via the introduction of the `hub_project_id`.
+variable. If you specify this variable, the cluster will be registered to this project and the GKE cluster will be deployed in the project specified in the `project_id` variable.
+
+To upgrade to the latest version, you will need to remove the state for the `run_destroy_command[0]` resource because, as of this release we register / unregister clusters using the `--gke-uri` option.
+
+If you run into errors during upgrade, you can remove the state for the run_destroy_command resource by running:
+`terraform state rm module.hub.module.gke_hub_registration.null_resource.run_destroy_command[0]`
