- It is now possible to upload certificates required to join a new control-plane to kubeadm-certs secret using the flag `--experimental-upload-certs` on `init` or upload-certs phase. ([#73907](https://github.com/kubernetes/kubernetes/pull/73907), [@yagonobre](https://github.com/yagonobre))

  - `kubeadm config upload` has been deprecated, as its replacement is now graduated. Please use `kubeadm init phase upload-config` instead. ([#77946](https://github.com/kubernetes/kubernetes/pull/77946), [@Klaven](htt...

## 0.15.0

* Add support for multiple file uploads (as a single form field). New docs at: [Multiple file uploads](https://fastapi.tiangolo.com/tutorial/request-files/#multiple-file-uploads). PR [#158](https://github.com/tiangolo/fastapi/pull/158).

- Kubeadm: add the "--kubeconfig" flag to the "kubeadm init phase upload-certs" command to allow users to pass a custom location for a kubeconfig file. ([#94765](https://github.com/kubernetes/kubernetes/pull/94765), [@zhanw15](https://github.com/zhanw15)) [SIG Cluster Lifecycle]

- Kubeadm: do not upload kubelet patch configuration into `kube-system/kubelet-config` ConfigMap ([#123108](https://github.com/kubernetes/kubernetes/pull/123108), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- Kubeadm: do not upload kubelet patch configuration into `kube-system/kubelet-config` ConfigMap ([#123093](https://github.com/kubernetes/kubernetes/pull/123093), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- [KCCM] drop filtering nodes for the providerID when syncing load balancers, but have changes to the field trigger a re-sync of load balancers. This should ensure that cloud providers which don't specify providerID, can still use the service controller implementation to provision load balancers.

- Kubeadm: do not upload kubelet patch configuration into `kube-system/kubelet-config` ConfigMap ([#123106](https://github.com/kubernetes/kubernetes/pull/123106), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

## Dependencies

* Add a label which prevents a node from being added to a cloud load balancer ([#53146](https://github.com/kubernetes/kubernetes/pull/53146), [@brendandburns](https://github.com/brendandburns))

### SIG Azure

* The Azure cloud provider now supports standard SKU load balancer and public IP.
`excludeMasterFromStandardLB` defaults to true, which means master nodes are excluded from the standard load balancer. Also note that because all nodes (except master) are added as loadbalancer backends, the standard load balancer doesn't work with the `service.beta.kubernetes.io/azure-load-balancer-mode` annotation.
