Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Sphinx 3:

Let us know here if you have any questions.

Sphinx 3 will be included in Fedora 33. To make that update smoother, we're building the dependent packages in Copr.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
