* 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))

### 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))

- Some interfaces' signatures in the scheduler were updated: - PluginsRunner: used NodeInfo in `RunPreScorePlugins` and `RunScorePlugins`. - PreScorePlugin: used NodeInfo in `PreScore`. - Extender: used NodeInfo in `Filter` and `Prioritize`.

* 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))

* Add tolerations for Stackdriver Logging and Metadata Agents. ([#69737](https://github.com/kubernetes/kubernetes/pull/69737), [@qingling128](https://github.com/qingling128))
* Fix scheduler crashes when Prioritize Map function returns error. ([#69618](https://github.com/kubernetes/kubernetes/pull/69618), [@DylanBLE](https://github.com/DylanBLE))

* 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))

- Added support for installing `arm64` node artifacts. ([#99242](https://github.com/kubernetes/kubernetes/pull/99242), [@liu-cong](https://github.com/liu-cong))

  // If not specified, the pod priority will be default or zero if there is no
