- Migrated `pkg/scheduler/framework/preemption/preemption.go`, `pkg/scheduler/framework/plugins/examples/stateful/stateful.go`, and `pkg/scheduler/framework/plugins/noderesources/resource_allocation.go` to structured logging ([#105967](https://github.com/kubernetes/kubernetes/pull/105967), [@shiv...

### Bug or Regression

- Fix a scheduler preemption issue where the victim pod was not deleted due to incorrect status patching. This issue occurred when the preemptor and victim pods had different QoS classes in their status, causing the preemption to fail entirely. ([#126695](https://github.com/kubernetes/kubernetes/pull/126695), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]

*   Pod preemption has been improved.
    *   Now takes PodDisruptionBudget into account. ([#56178](https://github.com/kubernetes/kubernetes/pull/56178),[ @bsalamat](https://github.com/bsalamat))

### Bug or Regression

- Fix data race in kube-scheduler when preemption races with a Pod update. ([#116440](https://github.com/kubernetes/kubernetes/pull/116440), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

- 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), [@H...

* kubeadm: explicitly wait for `etcd` to have grown when joining a new control plane ([#72984](https://github.com/kubernetes/kubernetes/pull/72984), [@ereslibre](https://github.com/ereslibre))
* Improve efficiency of preemption logic in clusters with many pending pods. ([#72895](https://github.com/kubernetes/kubernetes/pull/72895), [@bsalamat](https://github.com/bsalamat))

- Fewer candidates are enumerated for preemption to improve performance in large clusters. ([#94814](https://github.com/kubernetes/kubernetes/pull/94814), [@adtac](https://github.com/adtac))
