- Kube-scheduler implemented scheduling hints for the `NodeAffinity` plugin. The scheduling hints allowed the scheduler to only retry scheduling a Pod that had been previously rejected by the `NodeAffinity` plugin if a new Node...

- Removed kube-scheduler insecure flags. You can use `--bind-address` and `--secure-port` instead. ([#106865](https://github.com/kubernetes/kubernetes/pull/106865), [@jonyhy96](https://github.com/jonyhy96))
- Removed the `ImmutableEphemeralVolumes` feature gate. ([#107152](https://github.com/kubernetes/kubernetes/pull/107152), [@mengjiao-liu](https://github.com/mengjiao-liu))

  - the NormalizeScore plugin set is removed from scheduler framework config API. Use ScorePlugin only. ([#80930](https://github.com/kubernetes/kubernetes/pull/80930), [@liu-cong](https://github.com/liu-cong))

- Base-images: Update to `debian-base:buster-v1.7.1` ([#102594](https://github.com/kubernetes/kubernetes/pull/102594), [@mengjiao-liu](https://github.com/mengjiao-liu))
- Deprecated warning message for `igonre-errors` flag. ([#102677](https://github.com/kubernetes/kubernetes/pull/102677), [@yuzhiquan](https://github.com/yuzhiquan))

- Fixed the `PodAndContainerStatsFromCRI` feature, instead of supplementing with stats from cAdvisor. ([#113291](https://github.com/kubernetes/kubernetes/pull/113291), [@mengjiao-liu](https://github.com/mengjiao-liu))
- Fixed the occasional double-counting of the `job_finished_total` metric. ([#112948](https://github.com/kubernetes/kubernetes/pull/112948), [@mimowo](https://github.com/mimowo))

- Pod SecurityContext and PodSecurityPolicy supports slash as sysctl separator. ([#106834](https://github.com/kubernetes/kubernetes/pull/106834), [@mengjiao-liu](https://github.com/mengjiao-liu)) [SIG Apps, Architecture, Auth, Node, Security and Testing]

    * This keeps the behavior consistent with Docker integration, and fixes an issue that some container Prometheus metrics don't work when there are summary stats for multiple instances of the same pod.
