Nope. A new minor release of Python is a massive undertaking which is why we have saved ourselves the hassle of doing a Python 2.8 or not giving a clear signal as to when Python 2.x will end as a language. Why not just define Python 2.8 as Python 2.7 except with a newer compiler? I cannot see why that would be massive undertaking, if changing compiler for 2.7 is neccesary anyway. This would require recompiling all packages on OS X and Linux, even though nothing had changed.

If you are suggesting that a Windows compiler change should be invisible to non-Windows users, I agree.

Let us assume that /pcbuild remains for those who have vc2008 and that /pcbuild14 is added (and everything else remains as is). Then the only other thing that would change is the Windows installer released on Python.org. Call than 2.7.9W or whatever on the download site and interactive startup message to signal that something is different.
