- Fixed 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.

### 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]

- A terminating pod on a node that is not caused by preemption no longer prevents `kube-scheduler` from preempting pods on that node
  - Rename `PreemptionByKubeScheduler` to `PreemptionByScheduler` ([#114623](https://github.com/kubernetes/kubernetes/pull/114623), [@Huang-Wei](https://github.com/Huang-Wei))

- The Daemonset controller creates replacements for terminal Pods, which can appear during VM preemptions or when using Pod finalizers ([#118912](https://github.com/kubernetes/kubernetes/pull/118912), [@alculquicondor](https://github.com/alculquicondor)) [SIG Apps and Testing]

- Fixed an issue in asynchronous preemption: Scheduler now checks if preemption is ongoing for a Pod before initiating new preemption calls. ([#134730](https://github.com/kubernetes/kubernetes/pull/134730), [@ania-borowiec](https://github.com/ania-borowiec)) [SIG Scheduling and Testing]

- Added kubectl explain -r flag as a shorthand for --recursive ([#135283](https://github.com/kubernetes/kubernetes/pull/135283), [@laervn](https://github.com/laervn)) [SIG CLI]
- Align the meaning of victim metrics between async preemption and sync preemption. The definition has been standardized to refer to the number of Pods chosen as victims. ([#135955](https://github.com/kubernetes/kubernetes/pull/135955), [@utam0k](https://github.com/utam0k)) [SIG Scheduling]

- Fixed a suboptimal scheduler preemption behavior where potential preemption victims were violating Pod Disruption Budgets. ([#128435](https://github.com/kubernetes/kubernetes/pull/128435), [@NoicFank](https://github.com/NoicFank)) [SIG Scheduling]
