### 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. 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.
