Hi. Please kindly release a new version.

django-celery-beat try to release a new version but failed because sphinx_celery warning, which has been solved in #40

I believe the version should be 2.0.1 since most commits between 2.0.0 and HEAD are fixes

Would be happy to open a PR if any instruction.
