Warning: This is many years old and dead. Don't use it.
Just an interim release for now as I don't have my proper dev environment (TV, Pi-compatible internet connection, etc.). Once I figure out a way of getting networking to my Pi, I'll throw in the promised features such as USB audio support.
No idea at all if this works (I can't do much more than play about in the menu with no networking), but it certainly seems a lot smoother and more responsive than r2.
There's been no significant changes on my part, but likely a very significant amount from upstream (namely the extra codecs, 512mb support, etc.).
