* handle gracefully problem when kubelet reports duplicated stats for the same container (see [#47853](https://github.com/kubernetes/kubernetes/pull/47853)) on Heapster side
    * fixed bugs and improved performance in Stackdriver Sink

### Other (Cleanup or Flake)

- Reverts the EventedPLEG feature (beta, but disabled by default) back to alpha for a known issue ([#122720](https://github.com/kubernetes/kubernetes/pull/122720), [@pacoxu](https://github.com/pacoxu)) [SIG Node]

## Dependencies

### SIG Cloud Provider

- The cloudstack cloud provider now reports a `Hostname` address type for nodes based on the `local-hostname` metadata key. ([#67719](https://github.com/kubernetes/kubernetes/pull/67719), [@liggitt](https://github.com/liggitt))

### Other (Cleanup or Flake)

- Reverts the EventedPLEG feature (beta, but disabled by default) back to alpha for a known issue ([#122718](https://github.com/kubernetes/kubernetes/pull/122718), [@pacoxu](https://github.com/pacoxu)) [SIG Node]

## Dependencies

- `metadata.deletionTimestamp` is no longer moved into the future when issuing repeated DELETE requests against a resource containing a finalizer. ([#73138](https://github.com/kubernetes/kubernetes/pull/73138), [@liggitt](https://github.com/liggitt))

- Added validation to reject Pods using the `PodLevelResources` feature on Windows OS due to lack of support. The API server rejects Pods with Pod-level resources and a `Pod.spec.os.name` targeting Windows. Kubelet on nodes running Windows also rejects Pods with Pod-level resources at admission phase. ([#133046](https://github.com/kubernetes/kubernetes/pull/133046), [@toVersus](https://github.com/toVersus)) [SIG Apps and Node]

- Kube-apiserver now reports latency metric for JWT authenticator authenticate token decisions in the `apiserver_authentication_jwt_authenticator_latency_seconds` metric, labeled by jwtIssuer hash and result. ([#123225](https://github.com/kubernetes/kubernetes/pull/123225), [@aramase](https://github.com/aramase))

- Reverts adding namespace label to admission metrics (and histogram exansion) due to cardinality issues. ([#104033](https://github.com/kubernetes/kubernetes/pull/104033), [@s-urbaniak](https://github.com/s-urbaniak))

unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes.
Anyway, the cluster should get back to the proper size after 10 min.

### Deployment

- Kubectl create service now respects namespace flag ([#101005](https://github.com/kubernetes/kubernetes/pull/101005), [@zxh326](https://github.com/zxh326)) [SIG CLI]
