Python versions (Score: 2, Informative) by mth@pipedot.org on 2015-04-29 15:15 (#8286) [submitter's note]: some details in the announcements seemed a bit weird to me, notable, I quote, "The core requires Python 3.4 while Postorius and HyperKitty require Python 2.7.". Why use two different (and maybe incompatible) versions of python ?That's not a 'maybe': Python 2.x and 3.x are incompatible, since Python 3 made some backwards incompatible changes to clean up the language. While it is easy enough to run each process in a different Python version, it would simplify things if they just updated all subprojects to Python 3.x. There is a conversion tool for it (2to3) that works pretty well in my experience.
