- Fixed a 1.27 scheduling regression that PostFilter plugin may not function if previous PreFilter plugins return Skip ([#119943](https://github.com/kubernetes/kubernetes/pull/119943), [@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))

- 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.

 - 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))...

- Fix a bug that Pods with topologySpreadConstraints get scheduled to nodes without required labels. ([#95883](https://github.com/kubernetes/kubernetes/pull/95883), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]

   * onto the 1/rate (i.e. intervals) that is effective at the given storedPermits. "storedPermits"
   * essentially measure unused time; we spend unused time buying/storing permits. Rate is
   * "permits / time", thus "1 / rate = time / permits". Thus, "1/rate" (time / permits) times
   * "permits" gives time, i.e., integrals on this function (which is what storedPermitsToWaitTime()

- Fixed a scheduler panic when using PodAffinity. ([#82841](https://github.com/kubernetes/kubernetes/pull/82841), [@Huang-Wei](https://github.com/Huang-Wei))
- Take the context as the first argument of Schedule. ([#82119](https://github.com/kubernetes/kubernetes/pull/82119), [@wgliang](https://github.com/wgliang))
