v4.0.0

Feature

• Drop Python 3.6 support (#135) (8deebed)

Fix

• Cleanup Django compatibility shims for <2.0 (#126) (88cfb3b)

Breaking

• Python 3.6 is past end-of-life and is no longer supported. Keeping it in pyproject.toml was causing pains trying to install packages. Let's drop it while we're dropping support for other old stuff. (8deebed)

Documentation

• Add Django@4.0 to CI (#133) (20e2418)
