- Added `apiserver_watch_list_duration_seconds` metrics which will measure response latency distribution in seconds for watchlist requests broken by group, version, resource and scope. ([#120490](https://github.com/kubernetes/kubernetes/pull/120490), [@p0lyn0mial](https://github.com/p0lyn0mial))

- The scheduler skips the `InterPodAffinity` Score plugin when nothing to do with the Pod.
  It will affect some metrics values related to the InterPodAffinity Score plugin. ([#117794](https://github.com/kubernetes/kubernetes/pull/117794), [@utam0k](https://github.com/utam0k)) [SIG Scheduling]

	// The following deletions have no practical effect at this time
	// because state.vars has been reset by the preceding state.startBlock.
	// They only enforce the fact that these variables are no longer need in
	// the current scope.
	delete(s.vars, ptrVar)
	delete(s.vars, lenVar)
	if !inplace {
		delete(s.vars, capVar)
	}

	// make result
	if inplace {
		return nil
	}

- The Scheduler did not run the plugin Score method when its PreScore method returned a Skip status. In other words, the PreScore/Score plugin could return a Skip status in PreScore if the plugin did nothing in Score for that Pod.
