- The `kube-scheduler` `selectorSpread` plugin has been removed, please use the `podTopologySpread` plugin instead. ([#117720](https://github.com/kubernetes/kubernetes/pull/117720), [@kerthcet](https://github.com/kerthcet))
- The `matchLabelKeys/mismatchLabelKeys` feature is introduced to the hard/soft `PodAffinity/PodAntiAffinity`. ([#116065](https://github.com/kubernetes/kubernetes/pull/116065), [@sanposhiho](https://github.com/sanposhiho))
