*   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.

* GCE/GKE load balancer health check default interval changes from 2 seconds to 8 seconds, unhealthyThreshold to 3. ([#70099](https://github.com/kubernetes/kubernetes/pull/70099), [@grayluck](https://github.com/grayluck))
    * Health check parameters are configurable to be bigger than default values.
