* 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))

    *   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**

### 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))

* 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))

* 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))

### 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]

- 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))

  * New SchedulerExtender enables users to implement custom
out-of-(the-scheduler)-process scheduling predicates and priority functions,
for example to schedule pods based on resources that are not directly managed
