- Fix race in alpha aggregated discovery handler
  Yes, discovery document will correctly return the resources for aggregated apiservers that do not implement aggregated disovery ([#115805](https://github.com/kubernetes/kubernetes/pull/115805), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]

- Kube-proxy: added `--logging-format` flag to support structured logging. ([#117800](https://github.com/kubernetes/kubernetes/pull/117800), [@cyclinder](https://github.com/cyclinder))
- NodeVolumeLimits implement the `PreFilter` extension point for skipping the Filter phase if the Pod doesn't use volumes with limits. ([#115398](https://github.com/kubernetes/kubernetes/pull/115398), [@tangwz](https://github.com/tangwz)) [SIG Scheduling]

* Rename `--cgroups-per-qos` to `--experimental-cgroups-per-qos` in Kubelet ([#36767](https://github.com/kubernetes/kubernetes/pull/36767), [@vishh](https://github.com/vishh))
* Implement CanMount() for gfsMounter for linux ([#36686](https://github.com/kubernetes/kubernetes/pull/36686), [@rkouj](https://github.com/rkouj))

- The kubelet and the default docker runtime now support running ephemeral containers in the Linux process namespace of a target container. Other container runtimes must implement support for this feature before it will be available for that runtime.
