Looks like the product shots are missing the rulers, but you can still find them in KIT-10111; the overall board layout hasn’t changed, just the traces. You can read the reason for the change there as well.
Speaking of which, the Eagle Files link points to a zip of gerber files, but you can compare the boards from the product shots anyway :) The Eagle Files can, however, be found in the github repository: https://github.com/sparkfun/Tri-Color_Breakout.
