I have a forked branch[1] against a very old version of pyFF to make it work on Debian bookworm. The version is 1.1.5, but that is only tagged, not a branch so I can't make a PR against an upstream tag. It would be nice if you could branch from the 1.1.5 tag (call it the 1.1.x branch?) and let me PR against that branch. After that you can tag 1.1.6 and have a new version that can be deployed on bookworm.

1.1.5 was the last version with built-in discovery, that's what makes it so great for testing (we use that in InAcademia e.g.)
