The previous event was 2015-2016 Women's Grand Prix, Batumi. In that Batumi post I mentioned a fifth event that had not yet been scheduled. It is now listed on the FIDE calendar as:-
Women's FIDE Grand Prix Series; Khanty-Mansiysk, Russia; 12-Oct-2016 to 27-Oct-2016
Other than the updated calendar, I can find no announcement on the FIDE site.
