django-storages provides a variety of storage backends in a single library. Unfortunately it hasn’t seen a release since March of 2013 despite widespread usage and support for the library.
django-storages-redux is a Python 3 & Django 1.8+ compatible fork of the original library that’s thankfully seeing lots of ongoing maintenance and updates.
Switching over was fairly painless, with just a couple method signatures needing updates.
I highly recommend switching over if you haven’t already.
