 ### New Features {#new-features-1-17-0}
-* Adds partial rollback support where you can roll back from one version to another as long as the Embedded Cluster Config doesn't change between the two.
+* Adds support for partial rollbacks. Partial rollbacks are supported only when rolling back to a version where there is no change to the Embedded Cluster Config compared to the currently-installed version. For example, users can roll back to release version 1.0.0 after upgrading to 1.1.0 only if both 1.0.0 and 1.1.0 use the same [Embedded Cluster Config](/reference/embedded-config). For more information about how to enable rollbacks for your application in the KOTS Application custom resource, see [allowRollback](/reference/custom-resource-application#allowrollback) in _Application_.

 * **Changing node hostnames is not supported**: After a host is added to a Kubernetes cluster, Kubernetes assumes that the hostname and IP address of the host will not change. If you need to change the hostname or IP address of a node, you must first remove the node from the cluster. For more information about the requirements for naming nodes, see [Node name uniqueness](https://kubernetes.io/docs/concepts/architecture/nodes/#node-name-uniqueness) in the Kubernetes documentation.
