My phone is also updating, by the way. Through it's obvious that you shouldn't expect to much. It's probably just a bugfix release. Through they speak about "several improvements based on the feedback we’ve received", might be some new or changed wallpapers and new accent colors or that kind of small things? I dodn't know. However, I'm about to find out.
By the way, yesterday I was noticing that my battery was lasting longer. Probably because this new OS now feels normal and I'm not constantly playing with it.
