* You can now use `kubeadm token` specifying `--kubeconfig`.  In this case, kubeadm searches the current user home path and the environment variable KUBECONFIG for existing files. If provided, the `--kubeconfig` flag will be honored instead. ([#62850](https://github.com/kubernetes/kubernetes/pull/62850), [@neolit123](https://github.com/neolit123))...

* Add dns capabilities for Windows CNI plugins: ([#67435](https://github.com/kubernetes/kubernetes/pull/67435), [@feiskyer](https://github.com/feiskyer))
    * "dns" {

    *   "searches": ["default.svc.cluster.local","svc.cluster.local","cluster.local"],
    *   "options": []
    * }
