Yes, I think we are basically saying the same thing.  Internally we
need two branches and continuous merges, for everything done in the
translation toolchain part (and the JIT).  It doesn't really matter
which branch is called "a branch" or "the trunk" :-)  We can discuss
when the time comes how to give version numbers to the result.  Should
it be PyPy 1.6.1, 1.6.2, 1.6.3 and in parallel PyPy 2.0.1, 2.0.2,
2.0.3?...  The point I made originally was that I don't think we can
or should, for the foreseeable future, stop releasing newer versions
of PyPy supporting 2.7.


A bientôt,

Armin.
