* Introduce a new add-on pod NodeProblemDetector. ([#25986](https://github.com/kubernetes/kubernetes/pull/25986), [@Random-Liu](https://github.com/Random-Liu))

- Reduce default NodeStatusReportFrequency to 5 minutes. With this change, periodic node status updates will be send every 5m if node status doesn't change (otherwise they are still send with 10s).

  Bump NodeProblemDetector version to v0.8.0 to reduce forced NodeStatus updates frequency to 5 minutes. ([#84007](https://github.com/kubernetes/kubernetes/pull/84007), [@wojtek-t](https://github.com/wojtek-t))

  * Add generic Toleration for NoExecute Taints to NodeProblemDetector, so that NPD can be scheduled to nodes with NoExecute taints by default. ([#45883](https://github.com/kubernetes/kubernetes/pull/45883), [@gmarek](https://github.com/gmarek))

* AWS: support node port health check ([#43585](https://github.com/kubernetes/kubernetes/pull/43585), [@foolusion](https://github.com/foolusion))
* Add generic Toleration for NoExecute Taints to NodeProblemDetector ([#45883](https://github.com/kubernetes/kubernetes/pull/45883), [@gmarek](https://github.com/gmarek))
