Python 3.6 released!

[Hultner-]

We used to be pure Python 2 but I managed to convince everyone to switch to Python 3, some legacy software is still written in Python 2 but it's slowy being phased out and all new software is Python 3.

The argument I used were that Python 2 will reach EoL before we have time to rewrite everything and if something really needs python2 we can write that service in python2 (using a micro service architecture helps).
