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...

- API requests to deprecated versions now receive a warning header in the API response, and cause a metric indicating use of a deprecated API to be published:
  - `kubectl` outputs warnings to stderr, and accepts a `--warnings-as-errors` option to treat warnings as fatal errors

- 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. ([#104817](https://github.com/kubernetes/kubernetes/pull/104817), [@smarterclayton](https://github.com/smarterclayton))

    This helps prevent "split brain" scenarios in clustered applications by
    ensuring that unreachable pods will not be presumed dead unless some
    "fencing" operation has provided one of the above indications.
  * For all other existing controllers except StatefulSet, this has no effect on
    the ability of the controller to replace pods because the controllers do not
    reuse pod names (they use generate-name).

- Endpoints resources created by the Endpoints controller now include a label indicating this.
  Users who manually create Endpoints can also add this label, but they should consider

## 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))

### Federation
* The --dns-provider argument of 'kubefed init' is now mandatory and does not default to `google-clouddns`. To initialize a Federation control plane with Google Cloud DNS, use the following invocation: 'kubefed init --dns-provider=google-clouddns' ([#42092](https://github.com/kubernetes/kubernetes/pull/42092), [@marun](https://github.com/marun))

- 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.
