* Improve scheduler performance of MatchInterPodAffinity predicate. ([#57476](https://github.com/kubernetes/kubernetes/pull/57476), [@misterikkit](https://github.com/misterikkit))
* Improve scheduler performance of MatchInterPodAffinity predicate. ([#57477](https://github.com/kubernetes/kubernetes/pull/57477), [@misterikkit](https://github.com/misterikkit))

### Scheduling

- Only validate duplication of the RequestedToCapacityRatio custom priority and allow other custom predicates/priorities ([#84646](https://github.com/kubernetes/kubernetes/pull/84646), [@liu-cong](https://github.com/liu-cong))

    *   The VolumeScheduling feature gate must also be enabled on kube-scheduler and kube-controller-manager components.
    *   The NoVolumeNodeConflict predicate has been removed.  For non-default schedulers, update your scheduler policy.
    *   The CheckVolumeBinding predicate must be enabled in non-default schedulers. ([#55039](https://github.com/kubernetes/kubernetes/pull/55039),[ @msau42](https://github.com/msau42))

### **OpenStack**

* Performance of the affinity/anti-affinity predicate for the default scheduler has been significantly improved. ([#62211](https://github.com/kubernetes/kubernetes/pull/62211), [@bsalamat](https://github.com/bsalamat))

* Add error count and time-taken metrics for storage operations such as mount and attach, per-volume-plugin. ([#50036](https://github.com/kubernetes/kubernetes/pull/50036), [@wongma7](https://github.com/wongma7))

* Add a new kubelet endpoint for serving first-class resource metrics ([#73946](https://github.com/kubernetes/kubernetes/pull/73946), [@dashpole](https://github.com/dashpole))
* Deprecate AWS, Azure, GCE and Cinder specific volume limit predicates. ([#74544](https://github.com/kubernetes/kubernetes/pull/74544), [@gnufied](https://github.com/gnufied))

- Performance of the anti-affinity predicate of the default scheduler has been improved. ([#66948](https://github.com/kubernetes/kubernetes/pull/66948), [@mohamed-mehany](https://github.com/mohamed-mehany))

- Fixed [121094](https://github.com/kubernetes/kubernetes/issues/121094) by re-introducing the readiness predicate for `externalTrafficPolicy: Local` services. ([#121116](https://github.com/kubernetes/kubernetes/pull/121116), [@alexanderConstantinescu](https://github.com/alexanderConstantinescu))

* Aggregated used ports at the NodeInfo level for PodFitsHostPorts predicate. ([#42524](https://github.com/kubernetes/kubernetes/pull/42524), [@k82cn](https://github.com/k82cn))

### Bug or Regression

- Fix 121094 by re-introducing the readiness predicate for externalTrafficPolicy: Local services. ([#121116](https://github.com/kubernetes/kubernetes/pull/121116), [@alexanderConstantinescu](https://github.com/alexanderConstantinescu)) [SIG Cloud Provider and Network]
