- `EnqueueExtensions` from plugins other than `PreEnqueue`, `PreFilter`, `Filter`, `Reserve` and `Permit` are now ignored.
  It reduces the number of kinds of cluster events the scheduler needs to subscribe/handle. ([#121571](https://github.com/kubernetes/kubernetes/pull/121571), [@sanposhiho](https://github.com/sanposhiho))

- When `SchedulerQueueingHint` is enabled,
  the scheduler's in-tree plugins now subscribe to specific node events to decide whether to requeue Pods.
  This allows the scheduler to handle cluster events faster with less memory.

  Specific node events include updates to taints, tolerations or allocatable.
