- Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric
  - Errors in `IncreaseSize` changed from type `apiError` to `cloudProviderError`

- Consolidate ScoreWithNormalizePlugin into the ScorePlugin interface ([#83042](https://github.com/kubernetes/kubernetes/pull/83042), [@draveness](https://github.com/draveness))
- New APIs to allow adding/removing pods from pre-calculated prefilter state in the scheduling framework ([#82912](https://github.com/kubernetes/kubernetes/pull/82912), [@ahg-g](https://github.com/ahg-g))

* Use PostFilter instead of Postfilter in the scheduling framework ([#81800](https://github.com/kubernetes/kubernetes/pull/81800), [@draveness](https://github.com/draveness))
    * Use PreFilter instead of Prefilter in the scheduling framework
    * Use PreBind instead of Prebind in the scheduling framework

- PreFilter extension in the scheduler framework now returns not only status but also PreFilterResult ([#108648](https://github.com/kubernetes/kubernetes/pull/108648), [@ahg-g](https://github.com/ahg-g))

- Client-go: pass `DeleteOptions` down to the fake client `Reactor` (#102945, @chenchun) [SIG API Machinery, Apps and Auth]
- Enhance scheduler volumebinding plugin to handle Lost PVC as UnschedulableAndUnresolvable during PreFilter stage (#105245, @yibozhuang) [SIG Scheduling and Storage]
- Feature-gate `StorageObjectInUseProtection` has been deprecated and cannot be disabled. It will be completely removed in 1.25 (#105495, @ikeeip) [SIG Apps]

- Fixed a 1.26 regression scheduling bug by ensuring that preemption is skipped when a PreFilter plugin returns `UnschedulableAndUnresolvable` ([#119953](https://github.com/kubernetes/kubernetes/pull/119953), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
