Hey EJ, I can comment on a few changes that I recognized.
1) they've changed the hipbelt. It's now sewn in with a wishbone type connection. So imagine each end of the hipbelt being joined at the backpanel at 2 points, with a hole in the middle. It's suppose to wrap around better this way. You can see it clearly in the pack on the right.
2) Sternum strap has changed too. Instead of typical ITW hardwear that slides on a 1 inch piece of webbing, the sternum straps slide on a piping. Not sure why they did this.
3) I think they changed the material on the shoulder straps too. I haven't handled a 10' pack in a while, so i can't recall. It looks different in the pics, and I remember it being different than my 09 jam.
