Under "Reports" "Settings" "Miscellaneous" there are toggles for "Capturing a reserved village" and "Invalid village reservation". What is a "village reservation"?
Unless they're about to roll out an actual update, I assume it's something they planned to put in ages ago and never took it out. Tw1 and Grepolis have a system where your tribe can claim a village and everyone in the tribe and allies can see the reservations.
