* [Role-based access control (RBAC)](https://kubernetes.io//docs/admin/authorization/rbac) has graduated to beta, and defines secure default roles for control plane, node, and controller components.
* The [`kubeadm` cluster bootstrap tool](https://kubernetes.io/docs/getting-started-guides/kubeadm/) has graduated to beta. Some highlights:
  * **WARNING:** A [known issue](https://github.com/kubernetes/kubernetes/issues/43815)

- The `StructuredAuthenticationConfiguration` feature is now beta and enabled. ([#123719](https://github.com/kubernetes/kubernetes/pull/123719), [@enj](https://github.com/enj))
- The `kube_codegen` tool now ignores the vendor folder during code generation.
   ([#122729](https://github.com/kubernetes/kubernetes/pull/122729), [@jparrill](https://github.com/jparrill))

  - [alpha] The `kubeadm` tool makes it much easier to bootstrap Kubernetes. ([docs](http://kubernetes.io/docs/getting-started-guides/kubeadm/)) ([kubernetes/features#11](https://github.com/kubernetes/enhancements/issues/11))
- **Federation**

	* Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action.
