Kubernetes now allows users to define the cluster Service CIDR via an API object: ServiceCIDR.

## Changelog since v1.25.0-rc.0

## Changes by Kind

### Documentation

- Clarify that the node-port range (kube-apiserver config) must not overlap the nodes' ephemeral range. ([#111697](https://github.com/kubernetes/kubernetes/pull/111697), [@thockin](https://github.com/thockin)) [SIG Network]

### Bug or Regression

- The new `dra_resource_claims_in_use` kubelet metrics reported active `ResourceClaims`, overall and by driver. ([#131641](https://github.com/kubernetes/kubernetes/pull/131641), [@pohly](https://github.com/pohly)) [SIG Architecture, Instrumentation, Node and Testing]

* On GCI, NPD starts to monitor kubelet, docker, containerd crashlooping, read-only filesystem and corrupt docker overlay2 issues. ([#71522](https://github.com/kubernetes/kubernetes/pull/71522), [@wangzhen127](https://github.com/wangzhen127))

   ([#123271](https://github.com/kubernetes/kubernetes/pull/123271), [@neolit123](https://github.com/neolit123))
- kubeadm: improved the overall logic, error handling, and output messages when waiting for the kubelet and API server `/healthz` endpoints to return `OK`. The kubelet and API server checks no longer ran in parallel, but one after another (in serial).

* On GCI, NPD starts to monitor kubelet, docker, containerd crashlooping, read-only filesystem and corrupt docker overlay2 issues. ([#71522](https://github.com/kubernetes/kubernetes/pull/71522), [@wangzhen127](https://github.com/wangzhen127))

- Fixes `kubectl drain --dry-run=server`. ([#100206](https://github.com/kubernetes/kubernetes/pull/100206), [@KnVerey](https://github.com/KnVerey))
- Fixes an overly restrictive conformance test to accept service account tokens signed by an ECDSA key ([#100680](https://github.com/kubernetes/kubernetes/pull/100680), [@smira](https://github.com/smira)) [SIG Architecture, Auth and Testing]

  - 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.
