### 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]

- Fixed a bug that scheduler extenders are not called on preemptions. ([#103019](https://github.com/kubernetes/kubernetes/pull/103019), [@ordovicia](https://github.com/ordovicia))

- Migrate  `pkg/kubelet/pluginmanager`  to structured logging ([#99885](https://github.com/kubernetes/kubernetes/pull/99885), [@qingwave](https://github.com/qingwave)) [SIG Node]
- Migrate  `pkg/kubelet/preemption/preemption.go` and `pkg/kubelet/logs/container_log_manager.go` to structured logging ([#99848](https://github.com/kubernetes/kubernetes/pull/99848), [@qingwave](https://github.com/qingwave)) [SIG Node]

- Fix: return empty VMAS name if using standalone VM ([#103470](https://github.com/kubernetes/kubernetes/pull/103470), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Fixed a bug that scheduler extenders are not called on preemptions ([#103019](https://github.com/kubernetes/kubernetes/pull/103019), [@ordovicia](https://github.com/ordovicia)) [SIG Scheduling]

- 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]

* **[Pod priority and preemption](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/) is now enabled by default.** Note that this means that pods from *any* namespace can now request priority classes that compete with and/or cause preemption of critical system pods that are already running. If that is not desired, disable the PodPriority feature by setting `--feature-...
