All undamaged ships will now move instantly on the galactic map. No waiting for the 6 hour delay.
Also, lots of systems will be open to you simply because they have lots of planets in. If you have no RipCurrents you can still find someplace and someone to fight.
And these are the last rule changes I know of. No doubt I'll be adding some more Space Constructs over the next weeks and months, but I don't know of anything else effecting game play...at the moment.
