Ryzom code and assets released!

I read in the game programmers mailing list that the source code ant art of the Ryzom MMORPG has been released under GPL and CC licenses. You can see the official announce here and also get the links. Just a couple of things have not been released: the game database (obviously, to avoid user base fragmentation) and sounds and music. The FSF announce also includes details about how to get involved in the development.
Still there are some things left, like the world creation tools, but there is work in progress to let the process be handled with free software too.
