They just released 3.1.4 which is probably the last major patch before 3.2 drops. (no time frame for 3.2 yet)
The game still runs like junk on my computer. It is CPU locked to two cores (it would appear). So unless you have 4ghz quad core it wont run very well. They really badly need server optimizations but that was scheduled for 3.2 and has been pushed back to 3.3 or 3.4 (so 1 year out still)
It's getting really hard to continue to be optimistic about the game. What they have is fun but its not much content and it runs like crap.
