- Removed plugin watching of the deprecated directory `{kubelet_root_dir}/plugins` and CSI V0 support in accordance with deprecation announcement in https://v1-13.docs.kubernetes.io/docs/setup/release/notes ([#84533](https://github.com/kubernetes/kubernetes/pull/84533), [@davidz627](https://github.com/davidz627))

KubeletConfiguration is now always set to "systemd" unless the user is explicit about it. This requires existing machine setups to configure the container runtime to use the "systemd" driver. Documentation on this topic can be found here: https://kubernetes.io/docs/setup/production-environment/container-runtimes/. When upgrading existing clusters / nodes using "kubeadm upgrade" the old cgroupDriver value is preserved, but in 1.22 this change will also apply to "upgrade". For more information on migrating to the "systemd"...

`kubadm certs renew` will renew the certificate in `super-admin.conf` to one year if the file exists; if it does not exist a "MISSING" note will be printed. `kubeadm upgrade apply` for this release will migrate this particular node to the two file setup. Subsequent kubeadm releases will continue to optionally renew the certificate in `super-admin.conf` if the file exists on disk and if renew on upgrade is not disabled. `kubeadm join --control-plane` will now generate only an `admin.conf` file that...

- kubeadm: improved the `kubeadm reset` message for manual cleanups and referenced https://k8s.io/docs/reference/setup-tools/kubeadm/kubeadm-reset/. ([#129644](https://github.com/kubernetes/kubernetes/pull/129644), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

### Bug or Regression

- Added Extra.DisableAvailableConditionController for Generic Control Plane setup. ([#125650](https://github.com/kubernetes/kubernetes/pull/125650), [@mjudeikis](https://github.com/mjudeikis)) [SIG API Machinery]

- Updated pause image to version 3.5, which now runs per default as pseudo user and group `65535:65535`. This does not have any effect on remote container runtimes like CRI-O and containerd, which setup the pod sandbox user and group on their own. ([#100292](https://github.com/kubernetes/kubernetes/pull/100292), [@saschagrunert](https://github.com/saschagrunert))

- Kubelet: The `--azure-container-registry-config` flag has been deprecated and will be removed in a future release, please use `--image-credential-provider-config` and `--image-credential-provider-bin-dir` to setup acr credential provider instead. ([#118596](https://github.com/kubernetes/kubernetes/pull/118596), [@SataQiu](https://github.com/SataQiu)) [SIG Node]

- Remove ready file and its directory (which is created during volume SetUp) during emptyDir volume TearDown. ([#95770](https://github.com/kubernetes/kubernetes/pull/95770), [@jingxu97](https://github.com/jingxu97)) [SIG Storage]
