* Move hardPodAffinitySymmetricWeight to scheduler policy config ([#44159](https://github.com/kubernetes/kubernetes/pull/44159), [@wanghaoran1988](https://github.com/wanghaoran1988))

* Align Extender's validation with prioritizers. ([#45091](https://github.com/kubernetes/kubernetes/pull/45091), [@k82cn](https://github.com/k82cn))

* Disallow PriorityClass names with 'system-' prefix for user defined priority classes. ([#59382](https://github.com/kubernetes/kubernetes/pull/59382), [@bsalamat](https://github.com/bsalamat))
* kube-scheduler: Use default predicates/prioritizers if they are unspecified in the policy config. ([#59363](https://github.com/kubernetes/kubernetes/pull/59363), [@yguo0905](https://github.com/yguo0905))

- Introduce `v1beta3` API for scheduler. This version 
  - increases the weight of user specifiable priorities.
  The weights of following priority plugins are increased
    - `TaintTolerations` to 3 - as leveraging node tainting to group nodes in the cluster is becoming a widely-adopted practice
    - `NodeAffinity` to 2

- `maxThreshold` of `ImageLocality` plugin is now scaled by the number of images in the pod, which helps to distinguish the node priorities for pod with several images. ([#91138](https://github.com/kubernetes/kubernetes/pull/91138), [@chendave](https://github.com/chendave)) [SIG Scheduling]

### Documentation

### Alpha

- You can now create a non-preempting Pod priority (NonPreemptingPriority). If set on a class, the pod will continue to be prioritized above queued pods of a lesser class, but will not preempt running pods.

* Bump CNI consumers to v0.5.1 ([#43546](https://github.com/kubernetes/kubernetes/pull/43546), [@calebamiles](https://github.com/calebamiles))
