will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic outside the Kubelet, for instance by proxying the external endpoint rather...

- A pod that the Kubelet rejects was still considered as being accepted for a brief period of time after rejection, which might cause some pods to be rejected briefly that could fit on the node.  A pod that is still terminating (but has status indicating it has failed) may also still be consuming resources and so should also be considered.

## Metrics Changes

### Added metrics

- The metric `kube_proxy_sync_proxy_rules_last_timestamp_seconds` is now available, indicating the last time that kube-proxy successfully applied proxying rules. ([#74027](https://github.com/kubernetes/kubernetes/pull/74027), [@squeed](https://github.com/squeed))

- 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. ([#111661](https://github.com/kubernetes/kubernetes/pull/111661), [@alexanderConstantinescu](https://github.com/alexanderConstantinescu)) [SIG Network]

- Fixed the format of the error indicating that a user does not have permission on the object referenced by paramRef in ValidatingAdmissionPolicyBinding. ([#124653](https://github.com/kubernetes/kubernetes/pull/124653), [@m1kola](https://github.com/m1kola))

- Ingress:
  - `spec.ingressClassName` replaces the deprecated `kubernetes.io/ingress.class` annotation, and allows associating an Ingress object with a particular controller.

- New "field_validation_request_duration_seconds" metric, measures how long requests take, indicating the value of the fieldValidation query parameter and whether or not server-side field validation is enabled on the apiserver ([#109120](https://github.com/kubernetes/kubernetes/pull/109120), [@kevindelgado](https://github.com/kevindelgado))

* Introduces status conditions to the HorizontalPodAutoscaler in autoscaling/v2alpha1, indicating the current status of a given HorizontalPodAutoscaler, and why it is or is not scaling. ([#46550](https://github.com/kubernetes/kubernetes/pull/46550), [@DirectXMan12](https://github.com/DirectXMan12))

* The Kubelet now exports metrics that report the assigned (`node_config_assigned`), last-known-good (`node_config_last_known_good`), and active (`node_config_active`) config sources, and a metric indicating whether the node is experiencing a config-related error (`node_config_error`). The config source metrics always report the value `1`, and carry the `node_config_name`, `node_config_uid`, `node_config_resource_version`, and `node_config_kubelet_key...
