- Autoscaling/v2beta2 and custom_metrics/v1beta2 have been introduced, which implement metric selectors for Object and Pods metrics, as well as allowing AverageValue targets on Objects, similar to External metrics.

- ACTION REQUIRED: Support for basic authentication via the --basic-auth-file flag has been removed.  Users should migrate to --token-auth-file for similar functionality. ([#89069](https://github.com/kubernetes/kubernetes/pull/89069), [@enj](https://github.com/enj)) [SIG API Machinery]

    * "volume.alpha.kubernetes.io/storage-class" does not have any special meaning. A default storage class
    * and  DefaultStorageClass admission plugin can be used to preserve similar behavior of Kubernetes cluster,

parallelism and completions are spread across clusters. Federated Job
status reflects the aggregate status across all underlying cluster
jobs.

#### [alpha] Federated Horizontal Pod Autoscaling (HPA)

Federated HPAs are similar to the traditional Kubernetes HPAs, except
that they span multiple clusters. Creating a Federated HPA targeting
multiple clusters ensures that cluster-level autoscalers are

- `kubectl debug` gains support for changing container images when copying a pod for debugging, similar to how `kubectl set image` works. See `kubectl help debug` for more information. ([#96058](https://github.com/kubernetes/kubernetes/pull/96058), [@verb](https://github.com/verb)) [SIG CLI]

Kubeadm: Expose the `kubeadm join` workflow as phases

- Kubeadm: added support for dry running `kubeadm reset`. The new flag `kubeadm reset --dry-run` is similar to the existing flag for `kubeadm init/join/upgrade` and allows you to see what changes would be applied.

### Storage

- Kubeadm: when adding new control plane nodes with "kubeadm join", ensure that the etcd member addition is performed only if a given member URL does not already exist in the list of members. Similarly, on "kubeadm reset" only remove an etcd member if its ID exists.
