1.5.0

This version brings several improvements and enhancements in the internal API.
It is broadly compatible with the 1.4 series with the exception of the media component in the
WSGI strings. Importantly, multi-processing is handled directly by asyncio
rather than the multiprocessing module.
It is still possible to use the multiprocessing module via --concurrency multi
command line/config flag.
Support for uvloop has been added.
To use the this third party event loop, pass the --io uv flag in the command line.
