Hello, counterparts!
Can you merge this pull request? It's only one blocker for moving to Django 3.0 :)

Hey @ndavydovdev, @dmptrluke and @tiltec!

Apologies for not getting to this yet as I've been absolutely slammed. I promise I'll get this sorted and have a new Django 3.0-ready release minuted by this weekend. Stay tuned!
