- Limits lease to have 1000 maximum attached objects. ([#98257](https://github.com/kubernetes/kubernetes/pull/98257), [@lingsamuel](https://github.com/lingsamuel))

* Introduced `--http2-max-streams-per-connection` command line flag on api-servers and set default to 1000 for aggregated API servers. ([#60054](https://github.com/kubernetes/kubernetes/pull/60054), [@MikeSpreitzer](https://github.com/MikeSpreitzer))

  check for stale rules on every sync. (In smaller clusters, it will still
  remove unused rules immediately once they are no longer used.)

  (The threshold for "large" used here is currently "1000 endpoints" but
  this is subject to change.) ([#110334](https://github.com/kubernetes/kubernetes/pull/110334), [@danwinship](https://github.com/danwinship))

- Alpha swap support can now be enabled on Kubernetes nodes with the `NodeSwapEnabled` feature flag. See [KEP-2400](https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/2400-node-swap/README.md#design-details) for details.
