  The scheduling hints allow the scheduler to only retry scheduling a Pod
  that was previously rejected by the NodeSchedulable plugin if a new Node or a Node update sets .spec.unschedulable to false. ([#122334](https://github.com/kubernetes/kubernetes/pull/122334), [@carlory](https://github.com/carlory)) [SIG Scheduling]
- Kube-scheduler implements scheduling hints for the PodTopologySpread plugin.

- Fixed a 1.26 regression scheduling bug by ensuring that preemption is skipped when a PreFilter plugin returns `UnschedulableAndUnresolvable` ([#119952](https://github.com/kubernetes/kubernetes/pull/119952), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

- Kube-scheduler implements scheduling hints for the NodeAffinity plugin.
  The scheduling hints allow the scheduler to only retry scheduling a Pod
  that was previously rejected by the NodeAffinity plugin if a new Node or a Node update matches the Pod's node affinity. ([#119155](https://github.com/kubernetes/kubernetes/pull/119155), [@carlory](https://github.com/carlory)) [SIG Scheduling]
