Some smarter looking graphics/icons when forwarding emails. Some issues with photos, choosing/adjusting the HDR effect on a photo caused the photo app to crash back to the desktop, not a show stopper, and doesn't happen every time. There was some corruption in the headers for WhatsApp but this seem to have sorted itself out for now. Aside from those minor things, it seems pretty good so far, certainly seems stable. Battery life seems normal, not any worse than before. I started the update this morning when the battery was full, the update and usage throughout the day so far have left the battery at 46%, but it has been off charge since about 7.00AM and was not on charge during the update, it's 14.30 here now, so down a bit on what it would normally be but that's to be expected due to the update being quite taxing on the battery when installing.
