has been deprecated as part of the deprecation of Heapster. Instead, you may use the [metrics server](https://github.com/kubernetes-incubator/metrics-server). It's a simplified heapster that is able to gather and serve current metrics values. It 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...

- Improved misleading message, in case of no metrics received for the `HPA` controlled pods. ([#114740](https://github.com/kubernetes/kubernetes/pull/114740), [@kushagra98](https://github.com/kushagra98))
- Introduced new metrics removing the redundant subsystem in kube-apiserver pod logs metrics and deprecate the original ones:

- The scheduler retries gated Pods more appropriately, giving them a backoff penalty too. ([#126029](https://github.com/kubernetes/kubernetes/pull/126029), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
