### 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))

- Updated kubelet CLI summary documentation and generated webpage ([#73256](https://github.com/kubernetes/kubernetes/pull/73256), [@deitch](https://github.com/deitch))
- Set a low `oom_score_adj` for containers in pods with system-critical priorities ([#73758](https://github.com/kubernetes/kubernetes/pull/73758), [@sjenning](https://github.com/sjenning))

- 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

* Default mount propagation has changed...

- DRA: When the prioritized list feature was used in a request and the resulting number of allocated devices exceeded the number of allowed devices per claim, the scheduler aborted the attempt to allocate devices early. Previously, it tried to many different combinations,...

- Added DRA support for a "one-of" prioritized list of selection criteria to satisfy a device request in a resource claim. ([#128586](https://github.com/kubernetes/kubernetes/pull/128586), [@mortent](https://github.com/mortent)) [SIG API Machinery, Apps, Etcd, Node, Scheduling and Testing]

- Added `WithOrigin` within `apis/core/validation` with adjusted tests. ([#132825](https://github.com/kubernetes/kubernetes/pull/132825), [@PatrickLaabs](https://github.com/PatrickLaabs))
- Added scoring for the prioritized list feature so nodes that best satisfy the highest-ranked subrequests were chosen. ([#134711](https://github.com/kubernetes/kubernetes/pull/134711), [@mortent](https://github.com/mortent)) [SIG Node, Scheduling and Testing]

* Fix panic in kubectl rollout commands ([#69151](https://github.com/kubernetes/kubernetes/pull/69151), [@soltysh](https://github.com/soltysh))
* Fix scheduler crashes when Prioritize Map function returns error. ([#69135](https://github.com/kubernetes/kubernetes/pull/69135), [@DylanBLE](https://github.com/DylanBLE))

* 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))
