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...

production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar `kubeadm init` and `kubeadm join` commands to [configure and deploy an HA control plane](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/). An entire new test suite has been created specifically for ensuring these features will stay stable over time.

Certificate management has become more robust in 1.15, with kubeadm...

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

After its deprecation in v1.20, the dockershim component has been removed from the kubelet.
From v1.24 onwards, you will need to either use one of the other [supported runtimes](https://kubernetes.io/docs/setup/production-environment/container-runtimes/) (such as containerd or CRI-O)
or use cri-dockerd if you are relying on Docker Engine as your container runtime.

- kubeadm: fix "certificate-authority" files not being pre-loaded when using file discovery ([#80966](https://github.com/kubernetes/kubernetes/pull/80966), [@neolit123](https://github.com/neolit123))
- Add instruction to setup "Application Default Credentials" to run GCE Windows e2e tests locally. ([#81337](https://github.com/kubernetes/kubernetes/pull/81337), [@YangLu1031](https://github.com/YangLu1031))

- 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.

- 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.
