- NetworkPolicy resources will no longer be served from `extensions/v1beta1` in v1.16. Migrate use to the `networking.k8s.io/v1` API, available since v1.8. Existing persisted data can be retrieved via the `networking.k8s.io/v1` API.

	* gce kube-up: The Node authorization mode and NodeRestriction admission controller are now enabled ([#46796](https://github.com/kubernetes/kubernetes/pull/46796), [@mikedanese](https://github.com/mikedanese))

	* Tokens retrieved from Google Cloud with application default credentials will not be cached if the client fails authorization ([#46694](https://github.com/kubernetes/kubernetes/pull/46694), [@matt-tyler](https://github.com/matt-tyler))

  - PodSecurityPolicy resources will no longer be served from `extensions/v1beta1` in v1.16. Migrate to the `policy/v1beta1` API, available since v1.10. Existing persisted data can be retrieved via the `policy/v1beta1` API.

  In order to perform an unsafe deletion of a corrupt resource, the user must enable the option for the delete
  request. A resource is considered corrupt if it can not be successfully retrieved from the storage due to
  a) transformation error e.g. decryption failure, or b) the object failed to decode. Normal deletion flow is
  attempted first, and if it fails with a corrupt resource error then it triggers unsafe delete.

  - PriorityClass resources will no longer be served from `scheduling.k8s.io/v1beta1` and `scheduling.k8s.io/v1alpha1` in v1.17. Migrate to the `scheduling.k8s.io/v1` API, available since v1.14. Existing persisted data can be retrieved via the `scheduling.k8s.io/v1` API.

* `--feature-gates` argument has been removed from the `kubeadm join` command. Feature gates will be retrieved from the cluster configuration during the join process. ([#70755](https://github.com/kubernetes/kubernetes/pull/70755), [@ereslibre](https://github.com/ereslibre))

large LIST calls into multiple smaller chunks. A client can specify a limit to the number of results to return. If more results exist, a token is returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking, thanks to capabilities provided by etcd3.  This allows the server to use less memory and CPU when very large lists are returned. This feature is gated as APIListChunking...

- When the `RetryGenerateName` feature gate is enabled on the kube-apiserver,
  create requests using generateName are retried automatically by the apiserver when the generated name conflicts with an existing resource name, up to a max limit of 7 retries.
