Google has been publishing its security bulletin for the monthly Android patches for a long time, but starting October 2017 (last month), it created a special bulletin for Nexus and Pixel devices. With the newly released November patch, Google has started populating one new section in the bulletin that details "Functional updates."

So it was only a matter of time before the bulletin started mentioning these other non-security changes.

The October bulletin doesn't have anything in the "Functional updates" section, but the November one does. Here's what's included:
