### API Change

- The SchedulerAsyncAPICalls feature gate has been disabled to mitigate a bug where its interaction with asynchronous preemption in could degrade kube-scheduler performance, particularly under high kube-apiserver load. ([#134401](https://github.com/kubernetes/kubernetes/pull/134401), [@macsko](https://github.com/macsko)) [SIG Scheduling]

### Other (Cleanup or Flake)

- Fix: get azure disk lun timeout issue ([#88158](https://github.com/kubernetes/kubernetes/pull/88158), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Fixed `threadSafeMap` high memory usage caused by indices that have churn of high-cardinality keys. E.g. namespaces ([#88007](https://github.com/kubernetes/kubernetes/pull/88007), [@patrickshan](https://github.com/patrickshan)) [SIG API Machinery]
