The functionality of this redesigned site is 90% the same as the previous one. There have been a few minor tweaks, but it is essentially the same.
Some Internet Explorer users are experiencing some problems. That is mainly Because it is not a good browser, and is not really ABs fault. The ABTechies will work to overcome the glitches, and the site will settle down.
I am particularly impressed with the smartphone version. AB used to be terrible on phone, but the new version is a joy to use.
