Somewhere around 2007-2008 they upgraded their shifters and front derailleurs to "Quick Shift", which has a QS logo on the left shifter and on the FD.
As I understand it, the only difference in the levers is that they revised the left ratchet gear so that paddle lever engages a little more quickly (i.e. you don't have to push it as far inward towards the stem before you get the first click). They also revised the design of the FD so that it takes less force to move the cage towards the big chainring, at the expense of taking one extra click to traverse the distance. I believe these two features are independent, i.e. either type of FD will work fine with either type of lever. The most recent Campy groups have shuffled things around again so it gets a little more complicated, but I forget the details.
You can supposedly upgrade a non-QS left lever to QS by replacing the ratchet gear, though I don't know if it's worth the effort (the other components nitropowered mentioned come out anyway as part of a routine G-spring rebuild, but the ratchet gear looks like it takes a fair amount of extra disassembly).
