I bought the same one as the old one. Changes: the bottom is one piece, bad because if water gets on the bottom it is very difficult to dry. :the plastic of the sleeping part has been changed, now it creaks when there is an air mattress and you turn it on its side. :the entry flap is only on one side. :the changes to the fabric support on the small side are better than before. :the zippers are better. :the poles and pole tunnels are better. The norm when you try to improve, some things get worse and some get better.
