* The Certificates API has graduated from alpha to beta. This is a backwards-incompatible change since the alpha support is dropped, and therefore kubeadm v1.5 and v1.6 don't work together (for example kubeadm v1.5 can't join a kubeadm v1.6 cluster).
* Supporting only etcd3, with 3.0.14 as the minimum version.

- kube-scheduler dropped support for configuration files with apiVersion `componentconfig/v1alpha1`. Ensure kube-scheduler is configured using command-line flags or a configuration file with apiVersion `kubescheduler.config.k8s.io/v1alpha1` before upgrading to 1.13.

* Federation can now be deployed using the `federation/deploy/deploy.sh` script. This script does not depend on any of the development environment shell library/scripts. This is an alternative to the current `federation-up.sh`/`federation-down.sh` scripts. Both the scripts are going to co-exist in this release, but the `federation-up.sh`/`federation-down.sh`...

  Note that the default stored version remained alpha in 1.34, and whoever enabled beta during 1.34 needed to run a storage migration yourself to ensure you don't depend on alpha data in etcd.
