using COS images must be moved to the new directory, and installation processes must be updated with the new path. ([#58171](https://github.com/kubernetes/kubernetes/pull/58171), [@verult](https://github.com/verult))

* Default values differ between the Kubelet's componentconfig (config file) API and the Kubelet's command line. Be sure to review the default values when migrating to using a config file. For example, the authz mode is set to "AlwaysAllow" if you rely on the command line,...

* The kubeadm config option `API.ControlPlaneEndpoint` has been extended to take an optional port, which may differ from the apiserver's bind port. ([#62314](https://github.com/kubernetes/kubernetes/pull/62314), [@rjosephwright](https://github.com/rjosephwright))

* Fix kubeadm reset crictl command ([#55717](https://github.com/kubernetes/kubernetes/pull/55717), [@runcom](https://github.com/runcom))
* Fix code-generators to produce correct code when GroupName, PackageName and/or GoName differ. ([#55614](https://github.com/kubernetes/kubernetes/pull/55614), [@sttts](https://github.com/sttts))

If a container runtime does not support the `v1` API, Kubernetes will fall back to the `v1alpha2` implementation.
There is no intermediate action required by end-users, because `v1` and `v1alpha2` do not differ in their implementation.
It is likely that `v1alpha2` will be removed in one of the future Kubernetes releases to be able to develop `v1`.

### Structured logging graduate to Beta

- Kubeadm: remove the deprecated "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. This change also removes...

- `kubectl create clusterrolebinding` creates rbac.authorization.k8s.io/v1 object ([#85889](https://github.com/kubernetes/kubernetes/pull/85889), [@oke-py](https://github.com/oke-py)) [SIG CLI]
- `kubectl diff` now returns 1 only on diff finding changes, and >1 on kubectl errors. The "exit status code 1" message has also been muted. ([#87437](https://github.com/kubernetes/kubernetes/pull/87437), [@apelisse](https://github.com/apelisse)) [SIG CLI and Testing]

- Fixed OpenAPI serialization of the x-kubernetes-validations field ([#107970](https://github.com/kubernetes/kubernetes/pull/107970), [@liggitt](https://github.com/liggitt))
- Fixed failed flushing logs in defer function when kubelet cmd exit 1. ([#104774](https://github.com/kubernetes/kubernetes/pull/104774), [@kerthcet](https://github.com/kerthcet))

- Kubeadm: fixed a bug where the path of the manifest can not be specified when `kubeadm upgrade diff` specified a config file, and the `--api-server-manifest`, `--controller-manager-manifest` and `--scheduler-manifest` flags of `kubeadm upgrade diff` are marked as deprecated and will be removed in a future release. ([#125779](https://github.com/kubernetes/kubernetes/pull/125779), [@SataQiu](https://github.com/SataQiu))

- Adds `\livez` for liveness health checking for kube-apiserver. Using the parameter `--maximum-startup-sequence-duration` will allow the liveness endpoint to defer boot-sequence failures for the specified duration period.
