The new release won't really be as much about features, as it is simply a new design layout. There may be a few minor feature improvements, however it will operate almost just the same as it does currently. In fact, we plan to still offer this current version to those that want more of a standard "blog" type design, while the new one will be for those wanting more of a standard "ecommerce" type layout.
Hope this helps.
FYI: The new release is a couple of weeks out.
