aggregating status across all pods, maintaining application availability, and
rollback.
  * <strong>Automated cluster management: </strong>
     * Kubernetes clusters can now span zones within a cloud provider. Pods from a
service will be automatically spread across zones, enabling applications to
tolerate zone failure.
     * Simplified way to run a container on every node (DaemonSet API (Beta) in the

### Bug or Regression

- The new `-gce-zones` flag on the `e2e.test` binary instructs tests that check for information about how the cluster interacts with the cloud to limit their queries to the provided zone list. If not specified, the current behavior of asking the cloud provider for all available zones in multi zone clusters is preserved.
