### Other (Cleanup or Flake)

- Kube-apiserver: sets an upper-bound on the lifetime of idle keep-alive connections and time to read the headers of incoming requests ([#103958](https://github.com/kubernetes/kubernetes/pull/103958), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Node]

## Dependencies

- Fixed a bug that the async preemption feature keeps preemptor pods unnecessarily in the queue. ([#133167](https://github.com/kubernetes/kubernetes/pull/133167), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

  * Strategic Merge Patch

    * Reference docs now display the patch type and patch merge key used by `kubectl apply` to merge and identify unique elements in arrays.

      * `kubectl edit` and `kubectl apply` will keep the ordering of elements in merged lists ([#45980](https://github.com/kubernetes/kubernetes/pull/45980), [@mengqiy](https://github.com/mengqiy))

### Misc

  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it.

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
    * reconciler that does not do anything. This is useful for self-hosted
    * environments.
