Checked the only uberserver repository I could find (git://springlobby.info/git/aegis/uberserver.git) -- last updated in November. Is it still being developed? Is there another source tree I ought to be looking in? I'd rather not have to dig through someone else's code to figure out any protocol changes -- shouldn't have to, either, but I'm willing to resort to doing that for my own purposes if I need to.

I'd consider maintaining some sort of documentation for the protocol if I didn't have to dig through an implementation to find every new change.
