Cannot install latest release version (v0.3.0) with pip - new release?

[stringfellow]

Installing v0.3.0 which is on pypi (or v0.3.1 from GH) fails with a substitution error:

bash-4.4# pip install https://github.com/ludia/pyramid_metrics/archive/v0.3.1.zip
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

    ----------------------------------------

Installing from the latest commit (e9f1325) works fine. Is it possible to make a release with this fix to pypi?

Additionally, I'm using statsd 3.2.2 and it seems to work ok with pyramid_metrics, however the setup.py file for pyramid_metrics forces <2.2 -- is there any reason for this or is it just out of date?
