Howdy Folks. FNG saying Hi

Just joined today. Thanks for having me.
I'm literally going later today to purchase a used (Nov. 2012) Yoder YS480 Pellet Grill/Smoker and was just looking around the forum. First and main question is, has there been any major updates on the YS480 since the Nov. 2012 Manufacture date??
Just saw something about firmware / Software updates. How is that done? (Not a tech guy).
Again, thanks for having me. Looking forward to learning about this thing when I pick it up.
