3.9 + 0.1 :)

Renaming it to Python 4 is fraught with knock-on effects, so I think we do reserve that for major changes.  I doubt we’ll ever need for a disruptive backward incompatible change *at the Python level* in a Python 4, but I absolutely can see the possibility of incompatible changes at the public C API layer.  I’m not saying it *will* happen, but that’s what we should reserve “Python 4” for if or when it happens.
