SparkFun writes this about the newest revision: "The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector."
The difference they mention is compared to the FTDI cable
There is no difference between this board and older Basic FTDI breakout boards from Sparkfun. The guide you have found is valid.
I made an example for the previous version a while ago: http://perhof.wordpress.com/2011/11/19/breadboard-arduinos-and-sparkfun-ftdi-basic-breakout/
My version of the board is a bit more similar to the current one than the oldest one. It has the same pin-out, just a different connector.
