disallow updates to all fields other than `.status` (not just `.spec` and `.metadata` as before). Also, `required` and `description` can be used at the root of the CRD OpenAPI validation schema when the `/status` subresource is enabled.

In addition, users can now create multiple versions of CustomResourceDefinitions, but without any kind of automatic conversion, and CustomResourceDefinitions now allow specification of additional columns for `kubectl get` output via the `spec.additionalPrinterColumns`...

## Changelog since v1.6.8

### Other notable changes

* StatefulSet: Set hostname/subdomain fields on new Pods in addition to the deprecated annotations, to allow mitigation of Pod DNS issues upon upgrading to Kubernetes v1.7.x. ([#50942](https://github.com/kubernetes/kubernetes/pull/50942), [@enisoc](https://github.com/enisoc))

- Revert addition of Add `PersistentVolumeClaimDeletePoilcy` to `StatefulSet`API. ([#103747](https://github.com/kubernetes/kubernetes/pull/103747), [@mattcary](https://github.com/mattcary))

SIG Windows is also including several addition to this release:
 - Direct Server Return (DSR) mode support, allowing large numbers of services to scale up efficiently
 - Windows containers  now honor CPU limits

- Kubelet: Extended the `--image-credential-provider-config` flag to accept a directory path in addition to a single file. When a directory was specified, all .json, .yaml, and .yml files in that directory were loaded and merged in lexicographical order. ([#131658](https://github.com/kubernetes/kubernetes/pull/131658), [@dims](https://github.com/dims))...

  - [beta] `kube-apiserver` now publishes a swagger 2.0 spec in addition to a swagger 1.2 spec ([kubernetes/features#53](https://github.com/kubernetes/enhancements/issues/53))

* In order to bypass graceful deletion of pods (to immediately remove the pod from the API) the user must now provide the `--force` flag in addition to `--grace-period=0`.  This prevents users from accidentally force deleting pods without being aware of the consequences of force deletion.  Force deleting pods for resources like StatefulSets can result in multiple pods with the same name having...

Note that snapshot support will require Kubernetes distributors to bundle the Snapshot controller, Snapshot CRDs, and validation webhook. In addition, a CSI driver supporting the snapshot functionality must also be deployed on the cluster.
