- Fix error handling and potential go null pointer exception in kubeadm upgrade diff ([#80648](https://github.com/kubernetes/kubernetes/pull/80648), [@odinuge](https://github.com/odinuge))
- kubeadm: fall back to client version in case of certain HTTP errors ([#80024](https://github.com/kubernetes/kubernetes/pull/80024), [@RainbowMango](https://github.com/RainbowMango))

### Container Runtime Interface (CRI) v1 is default

The Kubelet now supports the CRI `v1` API, which is now the project-wide default.
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.

* Kubernetes will try to read the openstack auth config from the client config and fall back to read from the environment variables if the auth config is not available. ([#60200](https://github.com/kubernetes/kubernetes/pull/60200), [@dixudx](https://github.com/dixudx))

### SIG Scheduling

While breaking the input into tokens,
the next token is the longest sequence of characters that form a

- Fix the `cloudprovider_azure_api_request_duration_seconds` metric buckets to correctly capture the latency metrics. Previously, the majority of the calls would fall in the "+Inf" bucket.

  - true/strict - perform validation and error the request on any invalid fields in the ojbect. It will attempt to perform server-side validation if it is enabled on the apiserver, otherwise it will fall back to client-side validation.

however, kubectl v1.21 and older do not support the new API for ephemeral containers.
Users who create ephemeral containers using `kubectl debug` should note that kubectl version 1.22 will attempt to fall back to the old API; older versions of kubectl will not work with cluster versions of 1.22 or later. Please update kubectl to 1.22 if you wish to use `kubectl debug` with a mix of cluster versions.
