-   New internal `libmachine` package for internal api (not ready for public usage)
-   Updated Driver Interface
    -   [Driver Spec](https://github.com/docker/machine/blob/master/docs/DRIVER_SPEC.md)
    -   Removed host provisioning from Drivers to enable a more consistent install
    -   Removed SSH commands from each Driver for more consistent operations
-   Swarm: machine now uses Swarm default binpacking strategy
