*   You can now override the health check parameters for AWS ELBs by specifying annotations on the corresponding service. The new annotations are: `healthy-threshold`, `unhealthy-threshold`, `timeout`, `interval`. The prefix for all annotations is  `service.beta.kubernetes.io/aws-load-balancer-healthcheck-`.

* Introduce a new add-on pod NodeProblemDetector. ([#25986](https://github.com/kubernetes/kubernetes/pull/25986), [@Random-Liu](https://github.com/Random-Liu))
    * NodeProblemDetector is a DaemonSet running on each node, monitoring node health and reporting node problems as NodeCondition and Event. Currently it already supports kernel log monitoring, and will support more problem detection in the future. It is enabled by default on gce now.

- Health check of kube-controller-manager now includes each controller. ([#104667](https://github.com/kubernetes/kubernetes/pull/104667), [@jiahuif](https://github.com/jiahuif))

- Fixes #115825. Kube-proxy will now include the `healthz` state in its response to the LB HC as to avoid indicating to the LB that it should use the node in question when Kube-proxy is not healthy.

* Bump GLBC version to 0.9.5 - fixes [loss of manually modified GCLB health check settings](https://github.com/kubernetes/kubernetes/issues/47559) upon upgrade from pre-1.6.4 to either 1.6.4 or 1.6.5.

- Added a health check for the device plugin gRPC registration server. When the registration server is down, kubelet is marked as unhealthy. If systemd watchdog is configured, this will result in a kubelet restart. ([#128432](https://github.com/kubernetes/kubernetes/pull/128432),...
