Thanks Laurent! Do you think you'll be making Python 3 only releases by 2020? Would you like to add rpy2 to the statement?

Sure. If you need a logo you can snatch it from the doc page: http://rpy2.readthedocs.io/en/version_2.8.x/

I tried making rpy2 Python 3-only 4-5 years ago but I quickly realized that the world was not yet ready for that. Now seems the right time if there is a coordinated movement of the data-oriented Python ecosystem in that direction.

If the Gantt chart on the page is accurate, and projects do start with Python-3 only next year I am ready to make the current rpy2 release series (2.8.x) an LTS and make the next release series (2.9.x) Python 3-only (or if too much push back from user, this would be with 2.10.x in about a year / a year and a half).

It should be about time. I'm working on (hopefully) the last patch that make PyPI/PIP aware of the requires_python metadata (to use in setup.py) for Python-3 only version to not install on Python 2.x (and break for less users)

Once packages can start to be release we at least less fear.

rpy2 is now on board. Closing.
