* [alpha] This version now supports priority-based preemption of pods ([user doc](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/))([design doc](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/pod-preemption.md))

### Federation

* PodDisruptionBudget now uses [ControllerRef](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/api-machinery/controller-ref.md) to make the right decisions about Pod eviction even if the built in application controllers have overlapping selectors.

### **Security**
#### Admission Control

- The `--bind-address` parameter in kube-proxy is misleading, no port is opened with this address. Instead...

- Graduated Job's `ManagedBy` field to beta....

- Improved the documentation clarity for building Kubernetes in Docker Environment, making it more understandable for new users and contributors. ([#125536](https://github.com/kubernetes/kubernetes/pull/125536), [@this-is-yaash](https://github.com/this-is-yaash))

### SIG Multicluster

- Added the `DetectCacheInconsistency` feature gate, allowing the API server to periodically verify consistency between its `cache` and `etcd`. Detected inconsistencies...

- If a conflict occurs when creating an object with `generateName`, the server now returns an "AlreadyExists" error with a retry option....

  - If all QueueingHintFn return QueueSkip, it puts this pod back to the unschedulable pod pool
  
  Having appropriate QueueingHintFn contributes to reducing useless retries and thus improves the overall scheduler's performance.
  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff.
