 * There are breaking changes in the public API (such as the renaming of the `KubernetesDeploy` namespace to `Krane`, and the change in default values for different arguments of the public interface).

 * `kubernetes-deploy` (now `krane deploy`) / `DeployTask` can no longer deploy global (non-namespaced) resources. A new command called `krane global-deploy` and a related class called `GlobalDeployTask` were added to replace that feature.
 * `krane deploy` will not render erb templates. Use `krane render | krane deploy --stdin` to reproduce this functionality.
 * If you attempt to install two gems that have conflicting executables, `gem install` will warn you but the most recently installed one will win.
