Can we release new version `0.4.0`?

Hi dear maintainers,

I saw that there were a lot of commits, migrationg to GHA, adding support to Django4, flake8, isort etc... Could we release the new version to PyPi as a lot of people are blocked to upgrade to Django4 due to this library.

Best regards,
Sergei
