I've tried to push people toward Python 3, but I don't think everyone has made the switch.\r\n\r\nI'm still using Python 3.4 as my default Python right now.  I plan on switching to 3.5 at some point but just haven't gotten around to it yet.  In the future though questions like this should be addressed to the mailing list.  The issue tracker should only be used for issues in the code / feature requests."}}
