------------------
- [FIX] The function ``asyncio.ensure_future()`` called in
``aiomas.util.create_task()`` was introduced in Python 3.4.4 and is not
available in Python 3.4.0â3.4.3 (which is, e.g., used on Ubuntu 14.04).
There is now a fallback to ``asyncio.async()`` if ``asyncio.ensure_future()``
is not available.
