- Fix 1.28.0 regression where adding aggregated APIService objects could cause apiserver to panic and affect the health check ([#121040](https://github.com/kubernetes/kubernetes/pull/121040), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery and Testing]

*   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-`. ([#56024](https://github.com/kub...

* The kube-apiserver's healthz now takes in an optional query parameter which allows you to disable health checks from causing healthz failures.  ([#70676](https://github.com/kubernetes/kubernetes/pull/70676), [@logicalhan](https://github.com/logicalhan))

- 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.

* 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.

  Provided you enable the `KubeletFineGrainedAuthz` feature gate, you can access kubelet's `/healthz` endpoint by granting the caller `nodes/helathz` permission in RBAC.
  Similarly you can also access  kubelet's `/pods` endpoint to fetch a list of Pods bound to that node by granting the caller `nodes/pods` permission in RBAC.

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

* 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. ([#47567](https://github.com/kubernetes/kubernetes/pull/47567), [@nicksardo](https://github.com/nicksardo))

* 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.
