- update to 0.17.3:
* Fix #208, release v0.17.3 with proper meta data requiring Python >= 3.5.
* Add "python_requires >= 2.7" to setup.py in preparation for Python 2.7 incompatible updates
* Same as 0.17.1 released with more recent version of setuptools to get proper meta data for in place.
* Restrict package to Python >= 3.5 to not break unpinned Python 2 dependencies. Thanks @vphilippon
* Remove Python 2 support code. This includes dropping some compatibility code and the dependency on
six. Thanks @djailla for this.
* Fix #200, python 3 exception chaining. This is a minor backwards incompatibility, hence stepping
to 0.17.0. Thanks @cool-RR for this!
