They changed the layout a little bit and the technology mechanic a little bit.
Difference to the 2nd Edition Japanese: 10 cubes per color instead of 13.
12 technology cards instead of just 3.
Removed the technology space on the player cards where you keep track of the ship advancement and the money.
Instead of purchasing a technology by moving one of the 3 technology cubes into one of the 4 fields of the 3 technology cards you simply take one of the 12 technology cards and put it in front of you.
Since I received my copy by end of January 2014 this version was either published by the end of 2013 or in January 2014.
