### Bug or Regression

- The CPU Manager will now validate the state of the node,  enabling Kubernetes to maintain the CPU topology even if resources change. ([#66718](https://github.com/kubernetes/kubernetes/pull/66718), [@ipuustin](https://github.com/ipuustin))

provides the Metrics API that is used by `kubectl top`, and horizontal pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs in kube-dashboard and dedicated push sinks, which proved hard to maintain and scale.

  * We have renamed “minions” to “nodes”.  If you were specifying NUM\_MINIONS or
MINION\_SIZE to kube-up, you should now specify NUM\_NODES or NODE\_SIZE.

### Known Issues

  * Paused deployments can't be resized and don't clean up old ReplicaSets.

  * Clean up blackhole routes when using kubenet ([#47572](https://github.com/kubernetes/kubernetes/pull/47572), [@justinsb](https://github.com/justinsb))
