In addition to code/doc contributions, you can donate: http://pypy.org/py3donate.html http://pypy.org/py3donate.html The page mentions pypy3's current status as of August 2016: "We are soon releasing a beta supporting Python 3.3. For the next full year, though, see PyPy gets funding from Mozilla for Python 3.5 support. Individual donations through here are still welcome, and go towards the same goal, which is upgrading PyPy to support Python 3.x (which really means 3.3/3.5 by now). Thanks to all our past contributors! Your money has been put to good use so far."
