There was a list from Henry, but I can't find it now. I'll do my best to explain the bits I noticed.
First I would state that if you have an earlier version there is no need to change to the latest, but you could always pass yours to someone else and get the new one…
Here we go.
The most noticeable is the rear end. Now the top panel extends a few inches past the edge so that it offers better rain protection.
As you can see on the close up shot, the tie out has been re-enforced.
( On my 06 version, having forgotten that the sun moves in the sky, I came back from a walk in 40+C to find that rear peg a few meters away from the hole. The tension was enough to make it fly. But the guyline was still stitched in)
Also at the back, the guylines from the strut have been greatly simplified.
Sliding the rear up and down is also quicker and easier. (low for extra wind/rain protection)
The fly on the bottom area has been tweaked to make it rounder and tauter.
At the front, the beak now attaches under the side, much easier to open and close from the inside. The hook and loop is also wider (easier to match up when wet/cold/tired)
The floor can be re-tensioned whilst laying inside the tent. (pulling the guyline from the door end rather than the front)
Because of the tweaked geometry, it is very easy now to have the sides of the floor up (bathtub) .
All bits that I wished I had thought of, but I was too busy adding things and setting world records.
I forgot about the weight till after I applied my generous amount of seam sealer (I use 3x coats (!) over the tie out points and the apex), but It is about the same as before, so the specs on the TT page still apply.
