Upgrade from CVS is implemented. Before updating it check that you effetivelly have a CVS sandbox. In any case, restart it t and choose recompile after the update. Setup-0.1 This can be consider as the first complete release. Not everything should work however, but all major option are active.
Some bugs remains.
Some feature are not implemented. But it should be more than usable. Does't hurt in all cases. The current 0.1-2 version includes a minimal partially working version of the desktop. Not really usable at this stage, but you can have a look.
