This release adds game zones; these are different "arenas". People
can only join one of these zones at a time. Each zone is completely
independent of the others, and has its own economy, universe, and
players. The whole economy has been scaled down and balanced; you can no
longer make money as easily as in the past. A loss can now also be made
on a trade route.
