Python 2.6.6 was the final feature release of the 2.6 branch, it was
released in August 2010. Python 2.6.9 was the last security release, it
was released in October 2013. There is no support from upstream for 2.6,
either for bugs or security problems, OSX, linux, windows all have 2.7
available to them, as does VMWare in their environment.

Since no one any longer has a hard 2.6 requirement going to 2.7 seems
like a natural choice. It has more features, more modules, and better
3.x compatibility than 2.6 does.
