- `kubeadm`: a separate "super-admin.conf" file is now deployed. The User in `admin.conf` is now bound to a new RBAC Group `kubeadm:cluster-admins` that has `cluster-admin` `ClusterRole` access. The User in `super-admin.conf` is now bound to the `system:masters` built-in super-powers / break-glass Group that can bypass RBAC. Before this change, the default `admin.conf` was bound to `system:masters` Group, which was undesired. Executing `kubeadm init phase...

* The new flag `--apiserver-advertise-dns-address` is used in the node's kubelet.confg to point to the API server, allowing users to define a DNS entry instead of an IP address. ([#59288](https://github.com/kubernetes/kubernetes/pull/59288), [@stevesloka](https://github.com/stevesloka))

- kubeadm now deletes the bootstrap-kubelet.conf file after TLS bootstrap
  User relying on bootstrap-kubelet.conf should switch to kubelet.conf that contains node credentials ([#80676](https://github.com/kubernetes/kubernetes/pull/80676), [@fabriziopandini](https://github.com/fabriziopandini))

* Action Required: `kubeadm.k8s.io/v1beta1` has been deprecated, you should update...

- Kubelet: the following dockershim related flags are also removed along with dockershim `--experimental-dockershim-root-directory`, `--docker-endpoint`, `--image-pull-progress-deadline`, `--network-plugin`, `--cni-conf-dir`, `--cni-bin-dir`, `--cni-cache-dir`, `--network-plugin-mtu`.

- Kubernetes now correctly handles "search ." in the host's resolv.conf file by preserving the "." entry in the "resolv.conf" that the kubelet writes to pods. ([#109441](https://github.com/kubernetes/kubernetes/pull/109441), [@Miciah](https://github.com/Miciah)) [SIG Network and Node]

* Fix for resourcepool-path configuration in the vsphere.conf file. ([#66261](https://github.com/kubernetes/kubernetes/pull/66261), [@divyenpatel](https://github.com/divyenpatel))
