There is a "feature list" in README.md which is seen on the front-page of the GitHub repo and another one in setup.py which gets published to PyPI.
Currently these are maintained separately and it isn't uncommon for them to get out of sync.
It would be preferable to link these two so there is a single feature list to maintain. The best way forward I can see for that is to add a function to setup.py which parses the Markdown in README.md and extracts the feature list from there.
