configuring this). ([#97979](https://github.com/kubernetes/kubernetes/pull/97979), [@danwinship](https://github.com/danwinship)) [SIG Network and Node]

* `nodeSelector.matchFields` (node's `metadata.node`) is now supported in scheduler. ([#62453](https://github.com/kubernetes/kubernetes/pull/62453), [@k82cn](https://github.com/k82cn))
* Added a parametrizable priority function mapping requested/capacity ratio to priority. This function is disabled by default and can be enabled via the scheduler policy config file.

 - Reduced frequency of DescribeVolumes calls of AWS API when attaching/detaching a volume.
  Fixed "requested device X but found Y" attach error on AWS. ([#89894](https://github.com/kubernetes/kubernetes/pull/89894), [@johanneswuerbach](https://github.com/johanneswuerbach)) [SIG Cloud Provider]

### Deploy a more secure control plane with kubeadm

A new alpha feature allows running the kubeadm control plane components as non-root users. This is a long requested security measure in kubeadm. To try it you must enable the kubeadm-specific `RootlessControlPlane` feature gate. When you deploy a cluster using this alpha feature, your control plane runs with lower privileges.

- Fixes an issue where the vsphere cloud provider will not trust a certificate if:
  - The issuer of the certificate is unknown (x509.UnknownAuthorityError)
  - The requested name does not match the set of authorized names (x509.HostnameError)

- Only extend token lifetimes when `--service-account-extend-token-expiration` is true and the requested token audiences are empty or exactly match all values for `--api-audiences`.

* Allow remote admission controllers to be dynamically added and removed by administrators.  External admission controllers make an HTTP POST containing details of the requested action which the service can approve or reject. ([#46388](https://github.com/kubernetes/kubernetes/pull/46388), [@lavalamp](https://github.com/lavalamp))

* adding predicates ordering for the kubernetes scheduler. ([#57168](https://github.com/kubernetes/kubernetes/pull/57168), [@yastij](https://github.com/yastij))
* Free up CPU and memory requested but unused by Metrics Server Pod Nanny. ([#57252](https://github.com/kubernetes/kubernetes/pull/57252), [@kawych](https://github.com/kawych))

On-demand metrics calculation is now available through `/metrics/resources`. [When enabled](
https://docs.k8s.io/concepts/cluster-administration/system-metrics#kube-scheduler-metrics), the endpoint will report the requested resources and the desired limits of all running pods.
