- 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. ([#126644](https://github.com/kubernetes/kubernetes/pull/126644), [@Huang-Wei](https://github.com/Huang-Wei))

- 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 bug in kube-scheduler where pending pod preemption caused preemptor pods to be retried more frequently. ([#134247](https://github.com/kubernetes/kubernetes/pull/134247), [@macsko](https://github.com/macsko)) [SIG Scheduling and Testing]

- Graduated the asynchronous preemption feature in the scheduler to beta. 
  Now the feature flag (SchedulerAsyncPreemption) is enabled by default. ([#130550](https://github.com/kubernetes/kubernetes/pull/130550), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

    *   Added
        [`tf.distribute.experimental.PreemptionCheckpointHandler`](https://www.tensorflow.org/api_docs/python/tf/distribute/experimental/PreemptionCheckpointHandler)
        to handle worker preemption/maintenance and cluster-wise consistent
        error reporting for `tf.distribute.MultiWorkerMirroredStrategy`.
        Specifically, for the type of interruption with advance notice, it
