Is Dragonfly still supported in ray.tune?

Hi, it seems the documentation for using Dragonfly is invalid:
However, I can still see the code in ray package: So I’m wondering whether Dragonfly is deprecated or it is just an issue of the document page?

I’m asking because I’m trying some experiments for BO + discrete parameter space and following this article: A Novice’s Guide to Hyperparameter Optimization at Scale |, I was able to make Dragonfly works with discrete parameters. But if Dragonfly won’t be supported in the future, I think I would need to rethink about it.
