*   deviceplugin has been extended to more gracefully handle the full device plugin lifecycle, including: ([#55088](https://github.com/kubernetes/kubernetes/pull/55088),[ @jiayingz](https://github.com/jiayingz))
    *   Kubelet now uses an explicit cm.GetDevicePluginResourceCapacity() function that makes it possible to more accurately determine what resources are inactive and return a more accurate view of available resources.

* `kubectl wait` is a new command that allows waiting for one or more resources to be deleted or to reach a specific condition. It adds a `kubectl wait --for=[delete|condition=condition-name] resource/string` command. ([#64034](https://github.com/kubernetes/kubernetes/pull/64034), [@deads2k](https://github.com/deads2k))

#### Extensibility

- The community has been asking for continuing support of extensibility, so this cycle features more work around CRDs and API Machinery. Most of the enhancements in this cycle were from SIG API Machinery and related areas.

### Extensibility around core Kubernetes APIs

- Disable watchcache for events.k8.io/Event resource for compatibility with core/Event. ([#96117](https://github.com/kubernetes/kubernetes/pull/96117), [@wojtek-t](https://github.com/wojtek-t)) [SIG Scalability]

volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and
limits on ephemeral storage, the ability to specify mount options, more metrics, and improvements to Flex driver deployments.

[SIG Storage]: https://github.com/kubernetes/community/tree/master/sig-storage

## Before Upgrading

- `GetPodQOS(pod *core.Pod)` function now returns the stored value from `PodStatus.QOSClass`, if set. To compute/evaluate the value of `QOSClass` from scratch, `ComputePodQOS(pod*core.Pod)` must be used. ([#119665](https://github.com/kubernetes/kubernetes/pull/119665), [@vinaykul](https://github.com/vinaykul))

### SIG GCP

- GCE: decrease cpu requests on master node, to allow more components to fit on one core machine. ([#67504](https://github.com/kubernetes/kubernetes/pull/67504), [@loburm](https://github.com/loburm))

authz mode is set to "AlwaysAllow" if you rely on the command line, but defaults to the more secure "Webhook" mode if you load config from a file. ([#59666](https://github.com/kubernetes/kubernetes/pull/59666), [@mtaufen](https://github.com/mtaufen))

* [GCP kube-up.sh] Variables that were part of kube-env that were only used for kubelet flags are no longer being set, and are being replaced by the more portable mechanism of the kubelet configuration file. The individual variables in the...
