Fails with django 3.0 and python3.8

Hi there,

This is failing on django 3.0 and python 3.8, with the following error:


Traceback (most recent call last):

    from django.utils.encoding import python_2_unicode_compatible

I guess that's because in django 3 they dropped out all the python2 compatibility. Maybe launching a new version to all that stuff removed could be nice. It's time for python3 already :D
