Yes, we have stackless 3.3
But there is desire to have a 2.X version, with added fixes from 3.x, e.g. certain improvements in the
standard library etc.
It's the old argument:  moving to 3.x is not an option for some users, but there are known improvements that
can be applied to current 2.7.  Why not both have our cake and eat it?
cPython had probably two driving concerns for not making a 2.8:
1) Focussing development on one branch
2) encouraging (forcing) users to take the leap to 3 come hell or high water.

For Stackless, neither argument applies because 2.8 work would be done by us and stackless has no particular allegiance towards either version.
