### Bug or Regression

- Allow deletion of pods that use raw block volumes on node reboot ([#122211](https://github.com/kubernetes/kubernetes/pull/122211), [@gnufied](https://github.com/gnufied)) [SIG Node and Storage]

- Apimachinery/clock: This deletes the apimachinery/clock package. Please use k8s.io/utils/clock instead. ([#109752](https://github.com/kubernetes/kubernetes/pull/109752), [@MadhavJivrajani](https://github.com/MadhavJivrajani)) [SIG API Machinery]

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.
2) Alpha for CSI specification 0.3 integration to AWS EBS (Elastic Block Store)

- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI `NodeStageVolume` for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This change modified that behavior to ensure it is only called once per volume per node. ([#112403](https://github.com/kubern...

```Python
async def do_something():
    try:
        yield something
    finally:
        some_cleanup()
```

...that way the `finally` block is run regardless of any exception that might happen.

### Features

- Removed withdrawn feature `NetworkPolicyStatus`. ([#115843](https://github.com/kubernetes/kubernetes/pull/115843), [@rikatz](https://github.com/rikatz))

	   annotation, you should delete any existing NetworkPolicy
	   objects. These would have had no effect before, but with v1
	   semantics they might cause some traffic to be blocked that you
	   didn't intend to be blocked.

### Other notable changes

SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:
- Raw Block Support: Allow volumes to be surfaced as block devices inside containers instead of just mounted filesystems.
- Volume Cloning: Duplicate a PersistentVolumeClaim and underlying storage volume using the Kubernetes API via CSI.

- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI NodeStageVolume for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This PR ensures it is only called once per volume per node. ([#112403](https://github.com/kubernetes/kubernetes/pull/112403), ...
