* PSP: add support for using `*` as a value in `allowedCapabilities` to allow to request any capabilities ([#51337](https://github.com/kubernetes/kubernetes/pull/51337), [@php-coder](https://github.com/php-coder))

- The dockershim now sets the "bandwidth" and "ipRanges" CNI capabilities (dynamic parameters). Plugin authors and administrators can now take advantage of this by updating their CNI configuration file. For more information, see the [CNI docs](https://github.com/containernetworking/cni/blob/master/CONVENTIONS.md#dynamic-plugin-specific-fields-capabilities--runtime-configuration) ([#64445](https://github.com/kubernetes/kubernetes/pull/64445), [@squeed](htt...

[SIG Cluster Lifecycle][] is responsible for the user experience of deploying,
upgrading, and deleting clusters.

For the 1.8 release, SIG Cluster Lifecycle continued to focus on expanding the
capabilities of kubeadm, which is both a user-facing tool to manage clusters
and a building block for higher-level provisioning systems. Starting
with the 1.8 release, kubeadm supports a new upgrade command and includes alpha

  - 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))

  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))

- 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))

* Added a new `kubeadm upgrade node config` command. ([#64624](https://github.com/kubernetes/kubernetes/pull/64624), [@luxas](https://github.com/luxas))
* kubeadm now makes the CoreDNS container more secure by dropping (root) capabilities and improves the integrity of the container by running the whole container in read-only.  ([#64473](https://github.com/kubernetes/kubernetes/pull/64473), [@nberlee](https://github.com/nberlee))

- 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. ([#104732](https://github.com/kubernetes/kubernetes/pull/104732), [@mengjiao-liu](https://github.com/mengjiao-liu))

- The Kubelet's `--experimental-mounter-path` and `--experimental-check-node-capabilities-before-mount` options are now marked as deprecated. ([#91373](https://github.com/kubernetes/kubernetes/pull/91373), [@knabben](https://github.com/knabben))

  - 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**
