- Report kube-scheduler unhealthy if leader election is deadlocked. ([#71085](https://github.com/kubernetes/kubernetes/pull/71085), [@bsalamat](https://github.com/bsalamat))
- Fixed a potential bug that scheduler preempts unnecessary pods. ([#70898](https://github.com/kubernetes/kubernetes/pull/70898), [@Huang-Wei](https://github.com/Huang-Wei))

### SIG Storage

- A new extension point `PostFilter` is introduced to scheduler framework which runs after Filter phase to resolve scheduling filter failures. A typical implementation is running preemption logic. ([#91314](https://github.com/kubernetes/kubernetes/pull/91314), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]

- Fixed a scheduler racing issue to ensure low priority pods are unschedulable on the node(s) where high priority pods have `NominatedNodeName` set to the node(s).  ([#77990](https://github.com/kubernetes/kubernetes/pull/77990), [@Huang-Wei](https://github.com/Huang-Wei))

### Storage

 - The `CSIMigrationVSphereComplete` feature flag is removed. `InTreePluginvSphereUnregister` will be the way moving forward. ([#101272](https://github.com/kubernetes/kubernetes/pull/101272), [@Jiawei0227](https://github.com/Jiawei0227))...
