It is tonight that I finally publish all source code of April 08 Release.You can check it out following this guide.
From now on, I am going to use the SVN repository provided by Google Code. You can always keep an eye there.
There may be some other issues I am not aware now (‘cause I am not an SVN expert) but I will fix them all in a few days. Stay tuned.
(Update: If you failed to build the source on your machine, please read this post carefully.)
