- Fixed component status calling etcd health endpoint over http which exposed kubernetes to the risk of complete watch starvation and is inconsistent with other etcd probing done by `kube-apiserver`.

* [prototype] Volume snapshots

  * You can now create a volume snapshot by calling the Kubernetes API.

  * Note that the prototype does not support quiescing before snapshot, so snapshots might be inconsistent.

  * In the prototype phase, this feature is external to the core Kubernetes. It's available at https://github.com/kubernetes-incubator/external-storage/tree/master/snapshot.
