DeprecationWarning in Python 3.8

See original GitHub issue

@asyncio.coroutine was deprecated in Python 3.8 with https://github.com/python/cpython/pull/13346. loop argument is also deprecated. I am not sure async def can be used since the project ensures compatiblity with 3.3 and above whereas the syntax was present from 3.5 I guess. 3.4 also reached end of life.

I think dropping python 3.3 and 3.4 is fine
