I think, though I can't be sure, that the 3.06 one is the updated one. I know I have the updated one (I've used both); it has more format options, such as system, and the signature verification is default set to off, saves time. As I said, I'm not too sure about this, so you may want to find out more info. There was an updated page about the GNM recoveries on here, I guess search that and you should find it.
Good Luck. Have a nice day.
