* The server
 * component may a traditional NetBIOS name, a DNS name, or IP
 * address. These name resolution mechanisms and their resolution order
 * can be changed (See <a href="../../../resolver.html">Setting Name
 * Resolution Properties</a>). The servername and path components are

- If upgrading Cluster Federation components from 1.3.x, please ensure your cluster name is a valid DNS label (#30956, @nikhiljindal)
- kubelet's `--config` flag has been deprecated, use `--pod-manifest-path` instead (#29999, @mtaufen)

- Unallowed label values will show up as "unexpected" in all system components metrics ([#128100](https://github.com/kubernetes/kubernetes/pull/128100), [@yongruilin](https://github.com/yongruilin)) [SIG Architecture and Instrumentation]
