- Truncates a message if it hits the NoteLengthLimit when the scheduler records an event for the pod that indicates the pod has failed to schedule. ([#98715](https://github.com/kubernetes/kubernetes/pull/98715), [@carlory](https://github.com/carlory)) [SIG Scheduling]

    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).

- Added a new label `type` to `apiserver_flowcontrol_request_execution_seconds` metric - it has the following values: - 'regular': indicates that it is a non long running request - 'watch': indicates that it is a watch request. ([#105517](https://github.com/kubernetes/kubernetes/pull/105517), [@tkashem](https://github.com/tkashem))

- `MergeDefaultEvictionSettings` indicates that defaults for the evictionHard, evictionSoft, evictionSoftGracePeriod, and evictionMinimumReclaim fields should be merged into values specified for those fields in this configuration. Signals specified in this configuration take precedence. Signals...

### Autoscaling

- Horizontal Pod Autoscaling can now scale targets up even when one or more metrics are invalid/unavailable, as long as one metric indicates a scale up should occur. ([#78503](https://github.com/kubernetes/kubernetes/pull/78503), [@gjtempleton](https://github.com/gjtempleton))

- Truncates a message if it hits the NoteLengthLimit when the scheduler records an event for the pod that indicates the pod has failed to schedule. ([#98715](https://github.com/kubernetes/kubernetes/pull/98715), [@carlory](https://github.com/carlory)) [SIG Scheduling]

- The `rejected` label in `apiserver_admission_webhook_admission_duration_seconds` metrics now properly indicates if the request was rejected. ([#81399](https://github.com/kubernetes/kubernetes/pull/81399), [@roycaihw](https://github.com/roycaihw))

- Kubemark: added two flags, `--kube-api-qps` which indicates the maximum QPS to the apiserver, and `--kube-api-burst` which indicates maximum burst for throttle to the apiserver. ([#124147](https://github.com/kubernetes/kubernetes/pull/124147), [@devincd](https://github.com/devincd))
