You could email the company with the serial number or box info for the most solid answer. Alternatively, I threw a simple list together a while back when there was a bit of confusion over what was a known update or when. I've added anything new that I heard about and it might be helpful to see where your Mighty sits in this. Basically if you got that new box with mostly white, I think that's the most up to date one right now! The first few updates here are the most important imo, but a fully up to date Mighty is probably best if you can get it for the price you paid. Maybe there are errors or things missing from this too?
