Next Pokemon GO update starting to roll out on Android devices, adds data for Unova Pokemon

The next Pokemon GO update is starting to roll out on Android devices in some countries. This’ll bring the game up to version 0.153.0. Most significantly, this’ll add data for some Unova Pokemon to the game, which will start appearing soon. Dataminers have already been going through the update and found a new item, the Unova Stone. Pokemon like Minccino and Lampent that originally needed different stones to evolve will likely evolve using this Unova Stone in Pokemon GO, similar to how the Sinnoh Stone worked.
