Nima,
Head is a moving target right now.
The first alpha for 2.0 was just cut.

Beta soon to follow.
If you want to start in Mannheim you should be able to move from beta to beta to release. This is what we are going to do in Heidelberg.
Please check the testing servers and if you find the same problem post a bug.
