**Full Changelog**: https://github.com/dano/aioprocessing/compare/v2.0.0...v2.0.1

This release adds support for using `dill` for pickling, by using the `multiprocess` library if it is installed, instead of `multiprocessing`. If you have `dill` installed, but don't want to use it, launch your application with the environment variable `AIOPROCESSING_DILL_DISABLED=1`.

This release moves the minimum supported Python version to 3.5. It updates `aioprocessing` internals to use `async`/`await` syntax instead of `asyncio.coroutine`/`yield from`, and makes some linting fixes.
