- Added new option to the `InterPodAffinity` scheduler plugin to ignore existing
  pods` preferred inter-pod affinities if the incoming pod has no preferred inter-pod
  affinities. This option can be used as an optimization for higher scheduling throughput
  (at the cost of an occasional pod being scheduled non-optimally/violating existing
  pods preferred inter-pod affinities). To enable this scheduler option, set the

* [GCE] Apiserver uses `InternalIP` as the most preferred kubelet address type by default. ([#59019](https://github.com/kubernetes/kubernetes/pull/59019), [@MrHohn](https://github.com/MrHohn))

- The Image Locality priority function of the scheduler has been improved and is now enabled by default. With this feature enabled, nodes that have all or a partial set of images required for running a pod are preferred over other nodes, which improves pod start-up time.
- TaintNodeByCondition has been moved to Beta and is enabled by default.
- Scheduler throughput has been improved by ~50% in large clusters (>2000 nodes).

- The `PersistentVolumeLabel` admission controller in the API server is deprecated.

  - The replacement is running a cloud-specific controller-manager (often referred to as `cloud-controller-manager`) with the `PersistentVolumeLabel` controller enabled. This new controller loop operates as the `PersistentVolumeLabel` admission controller did in previous versions.

### Bug or Regression

- A node IP provided to kublet via `--node-ip` will now be preferred for when determining the node's primary IP and using the external cloud provider (CCM). ([#107750](https://github.com/kubernetes/kubernetes/pull/107750), [@stephenfin](https://github.com/stephenfin))

### Windows

- Kubeadm: support experimental JSON/YAML output for `kubeadm upgrade plan` with the `--output` flag. ([#108447](https://github.com/kubernetes/kubernetes/pull/108447), [@pacoxu](https://github.com/pacoxu))
- Kubeadm: the preferred pod anti-affinity for CoreDNS is now enabled by default. ([#110593](https://github.com/kubernetes/kubernetes/pull/110593), [@SataQiu](https://github.com/SataQiu))
