* kubectl cp now safely allows unpacking of symlinks that may point outside the destination directory ([#82384](https://github.com/kubernetes/kubernetes/pull/82384), [@tallclair](https://github.com/tallclair))
* fix azure disk naming matching issue due to case sensitive comparison ([#81720](https://github.com/kubernetes/kubernetes/pull/81720), [@andyzhangx](https://github.com/andyzhangx))

* kubeadm now detects the Docker cgroup driver and starts the kubelet with the matching driver. This eliminates a common error experienced by new users in when the Docker cgroup driver is not the same as the one set for the kubelet due to different Linux distributions setting different cgroup drivers for Docker, making it hard to start...

* kubectl port-forward now allows using resource name (e.g., deployment/www) to select a matching pod, as well as the use of --pod-running-timeout to wait until at least one pod is running. ([#59705](https://github.com/kubernetes/kubernetes/pull/59705), [@phsiao](https://github.com/phsiao))

- Added CEL runtime cost calculation into ValidatingAdmissionPolicy, matching the evaluation cost
  restrictions that already apply to CustomResourceDefinition.
  If rule evaluation uses more compute than the limit, the API server aborts the evaluation and the

    *   Added `namespaceSelector` to `externalAdmissionWebhook` configuration to allow applying webhooks only to objects in the namespaces that have matching labels. ([#54727](https://github.com/kubernetes/kubernetes/pull/54727),[ @caesarxuchao](https://github.com/caesarxuchao))

- Namespace API objects now have a `kubernetes.io/metadata.name` label matching their metadata.name field to allow selecting any namespace by its name using a label selector.

## Other notable changes
### API Machinery

- kube-apiserver: the `--runtime-config` flag now supports an `api/beta=false` value which disables all built-in REST API versions matching `v[0-9]+beta[0-9]+`. ([#84304](https://github.com/kubernetes/kubernetes/pull/84304), [@liggitt](https://github.com/liggitt))

- kube-apiserver: When using `--enable-admission-plugins` the `Priority` admission plugin is now enabled by default (matching changes in 1.11.1+). If using `--admission-control` to fully specify the set of admission plugins, it is now necessary to add the `Priority` admission plugin for the PodPriority feature to work properly. ([#65739](https://github.com/kubernetes/k...

* Advanced audit now correctly reports impersonated user info. ([#48184](https://github.com/kubernetes/kubernetes/pull/48184), [@CaoShuFeng](https://github.com/CaoShuFeng))

- Added optional `--detect-local-mode` flag to kube-proxy. Valid values are "ClusterCIDR" (default matching previous behavior) and "NodeCIDR" ([#87748](https://github.com/kubernetes/kubernetes/pull/87748), [@satyasm](https://github.com/satyasm)) [SIG Cluster Lifecycle, Network and Scheduling]
