- kubeadm: Promoted the feature gate `ControlPlaneKubeletLocalMode` to Beta. By default, kubeadm will use the local kube-apiserver endpoint for the kubelet when creating a cluster with `kubeadm init` or when joining control plane nodes with `kubeadm join`. Enabling the feature gate also affects the `kubeadm init phase kubeconfig kubelet` phase, where the flag `--control-plane-endpoint` no longer affects the generated kubeconfig `Server` field, but the flag `...

- `kubeadm`: promoted feature gate `EtcdLearnerMode` to `beta`. Learner mode for
  joining `etcd` members is now enabled by default. ([#120228](https://github.com/kubernetes/kubernetes/pull/120228), [@pacoxu](https://github.com/pacoxu))

## Known Issues

- Concurrently joining control-plane nodes does not work as expected in kubeadm 1.15.0. The feature was planned for release in 1.15.0, but a fix may  come in a follow up patch release.

- Kubeadm: do not check if the `/etc/kubernetes/manifests` folder is empty on joining worker nodes during preflight ([#104942](https://github.com/kubernetes/kubernetes/pull/104942), [@SataQiu](https://github.com/SataQiu))
