the following properties: "federations".
    * --federations flag is now deprecated. Prefer to set federations via the config-map.
      Federations can be configured by settings the "federations" field to the value currently
      set in the command line.
    * Example:
      ```yaml
      kind: ConfigMap
      apiVersion: v1
      metadata:

## Known Issues

### Summary API in kubelet doesn't have accelerator metrics

- Kubernetes now correctly handles "search ." in the host's resolv.conf file by preserving the "." entry in the "resolv.conf" that the kubelet writes to pods. ([#109441](https://github.com/kubernetes/kubernetes/pull/109441), [@Miciah](https://github.com/Miciah)) [SIG Network and Node]

### Bug or Regression

- Currently, NodeAdded QueueingHint could not always be called because of the internal feature called preCheck.
  It's definitely not something expected for plugin developers,

### Scheduling
* **Multiple schedulers**
  * Modify your PodSpecs that currently use the `scheduler.alpha.kubernetes.io/name` annotation on Pod, to instead use the `schedulerName` field in the PodSpec.

- Kubeadm: fixed a bug where the node registration information for a given node was not fetched correctly during "kubeadm upgrade node" and the node name can end up being incorrect in cases...

  
  - kind: StorageClass
  - apiVersion: storage.k8s.io/v1
  - metadata:
    - name: shared-disk
  - provisioner: kubernetes.io/azure-disk
  - parameters:
    - skuname: Premium_LRS  # Currently only available with premium SSDs.
    - cachingMode: None # ReadOnly host caching is not available for premium SSDs with maxShares>1

- Fixed an issue where the Service LoadBalancer controller was not correctly considering the `service.Status new IPMode` field and excluding the Ports when checking if the status was changed, resulting in the changed field potentially not to update the `service.Status` correctly.
