The new beta code is up and so is a new webpage with info:

The savegame logic is looking good, so please delete old savegame files and test the new code on all systems. Let me know about any problems you encounter and please give me some feedback on the new features.
L.B.
Forgot to mention that I enabled all of the new features for non-registered users to try also.
