Attention: I highly recommend installing from the wheel file on pypi. Use the source distro on this github page only when you need the complete source.
Changes:
- Verified support Python 3.5 and 3.6
- Distribution via wheel
- Abandon support for Python 2.x and easy_install; now requires Python >= 3.3
- Abandon support for long-ago deprecated arg1 messaging protocol
- Added currying of subscribed listener args
- Significant speed improvement for message delivery
- Use PEP 484 style of annotations throughout
- Use enum instead of constants when practical
