- Remove the deprecated flag `--experimental-check-node-capabilities-before-mount`. With CSI now GA, there is a better alternative. Remove any use of  `--experimental-check-node-capabilities-before-mount` from your kubelet scripts or manifests.

- Delegated authorization can now allow unrestricted access for `system:masters` like the main kube-apiserver ([#70671](https://github.com/kubernetes/kubernetes/pull/70671), [@deads2k](https://github.com/deads2k))
- Added dns capabilities for Windows CNI plugins: ([#67435](https://github.com/kubernetes/kubernetes/pull/67435), [@feiskyer](https://github.com/feiskyer))

  - Easier to understand a cluster (eg: API audit logs, server-based API defaults)
- **Stateful Application Support**
  - Enhanced persistence capabilities (eg: `StorageClasses`, new volume plugins)
  - New resources and scheduler features (eg: `ScheduledJob` resource, pod/node affinity/anti-affinity)
- **Cluster Federation**

  - Most of the containers now run as non-root user and has the root filesystem set as read-only.
  - The remaining container running as root only has the minimum Linux capabilities it requires to run.
  - Privilege escalation has been disabled for all containers. ([#82347](https://github.com/kubernetes/kubernetes/pull/82347), [@pjbgf](https://github.com/pjbgf))

- Show a warning message to inform users that the debug container's capabilities granted by debugging profile may not work as expected if a non-root user is specified in target Pod's `.Spec.SecurityContext.RunAsUser` field.

  validate any input config file. Use the `--config` flag to pass a config file
  to it. See the command `--help` screen for more information. As a result of adding
  this new command, enhance the validation capabilities of the existing "kubeadm
  config migrate" command. For both commands unknown APIs or fields will throw errors. ([#118013](https://github.com/kubernetes/kubernetes/pull/118013), [@neolit123](https://github.com/neolit123))

- Support for out of tree networking with Azure-CNI, OVN-Kubernetes and Flannel
- Improved support for pods, service types, workload controllers and metrics/quotas to closely match the capabilities offered for Linux containers

  honor the specified `scheme` and `headers` fields. This enables setting custom
  headers and changing the scheme to `HTTPS`, consistent with container
  startup/readiness/liveness probe capabilities. Lifecycle handlers configured
  with `scheme: HTTPS` that encounter errors indicating the endpoint is actually
  using HTTP fall back to making the request over HTTP for compatibility with
