- Fix performance regression in scheduler caused by frequent metric lookup on critical code path. ([#117617](https://github.com/kubernetes/kubernetes/pull/117617), [@tosi3k](https://github.com/tosi3k)) [SIG Scheduling]

* Disable proxy to loopback and linklocal ([#71980](https://github.com/kubernetes/kubernetes/pull/71980), [@micahhausler](https://github.com/micahhausler))
* kube-scheduler: restores ability to run without authentication configuration lookup permissions ([#71755](https://github.com/kubernetes/kubernetes/pull/71755), [@liggitt](https://github.com/liggitt))

resources, which represents the list of group aliases (e.g. "all") that every resource belongs to. ([#43338](https://github.com/kubernetes/kubernetes/pull/43338), [@fabianofranz](https://github.com/fabianofranz))

* `--service-account-lookup` now defaults to true, requiring the Secret API object containing the token to exist in order for a service account token to be valid. This enables service account tokens to be revoked by deleting the Secret object containing the token. ([#44071]...
