 * --extra-vars can now take a file as input "-e @filename"

 * external inventory scripts may now return host variables in one pass, which allows them to be much more efficient for large numbers of hosts

 * if --forks exceeds the numbers of hosts, it will be automatically reduced, set forks to 0 and you get "as many forks as I have hosts" out of the box.

+* enabling error_on_undefined_vars by default, which will make errors in playbooks more obvious
