[Python-Dev] Backward-incompatible change to random.randrange in 2.7.6

[Guido van Rossum]

BTW, I bet a lavish dinner at PyCon that it is *only* Zope/ZODB that
does this. In the time we added this bogus dependency on undocumented
parameters, the PythonLabs team was at Zope and we didn't always get
our boundaries straight.
