Wow! That is most interesting news in that (apparently) this update has yet to flow to everyone with the "auto" install feature enabled. Thanks for finding the notes and posting such, 'tis greatly appreciated!
10.0.1 is the official release. iPhone 7s came with iOS 10.0 installed, requiring the update to 10.0.1. That means there were critical bugs that needed to be fixed in between the time the devices were built and the release of iOS 10. First time that devices have ever received an outdated GM.
