Social Media Settings-Renee Smith

I reviewed my personal FB page settings. For the most part I have turned off most items for the public to see. But, I noticed that there is a new section in the settings that was not there in previous sessions when reviewing my settings. I wonder how FB communicates these setting changes to their customers. Do we receive an email that we perceive as being "junk" information? When do these changes happen-hopefully not often? Is it yearly?

I wish Facebook would share when they change settings. I think I have them all set up right, next thing I know something has changed.
