Need to port to Python 3 this year (2019) - support for 2.7 drops at the start of 2020.
No longer any blocking dependencies -
django-pagination no longer being used,
django-qsstats-magic has been upgraded to support Python 3, and presumably
django-solo has too.
No point attempting to support Python 2.7 and Python 3 simultaneously - all users will need to go through the pain of the upgrade, we may as well go through it together! Also, targeting Django 2.2 which only supports Python 3.5 to 3.7.
