Major features/changes:
* The deprecated legacy variable templating system has been finally removed. Use {{ foo }} always not $foo or ${foo}.
* Any data file can also be JSON. Use sparingly -- with great power comes great responsibility. Starting file with "{" or "[" denotes JSON.
* Added 'gathering' param for ansible.cfg to change the default gather_facts policy.
* Accelerate improvements:
- multiple users can connect with different keys, when `accelerate_multi_key = yes` is specified in the ansible.cfg.
- daemon lifetime is now based on the time from the last activity, not the time from the daemon's launch.
* ansible-playbook now accepts --force-handlers to run handlers even if tasks result in failures.
* Added VMWare support with the vsphere_guest module.
