    * Remove deprecated ContainerVM support from GCE kube-up.  ([#58247](https://github.com/kubernetes/kubernetes/pull/58247), [@mikedanese](https://github.com/mikedanese))

    * Remove deprecated kube-push.sh functionality.  ([#58246](https://github.com/kubernetes/kubernetes/pull/58246), [@mikedanese](https://github.com/mikedanese))

  * `daemonset-lookup-cache-size`

  Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

* The following deprecated flags were removed from `kubelet`:

  * `api-servers` - add apiserver addresses to the kubeconfig file instead.
