231 MB 360 live update download?!

I am set up for automative Live Updates, and I also check it frequently and run it manually as well. Today, July 25, 2014 there is a 231.22 MB download!!! Is this for real? I have never seen a download of that size in several years of using Live Update. I have 301 days left on my subscription, so I know it can't be a new program download, can it? What g.ives? And yes, I did restart and I am meticulous about clearing caches, Temp and Recent file folders on my system
