If you're talking about the updated version of Null's Brawl with new fighters Lily and Draco, it's still in development because the developers found some bugs and are working on fixing them now. I think when they fix them and release the new version, they will post news about it here https://nulls-brawl.com/. And overall, Null's Brawl is a great private server that, no matter what, is updated regularly and only gets better every time.
