A new update for Pokemon GO is being rolled out today, which adds a new reward for those who frequent Pokestops.
Among a few bug and text fixes, fans who visit Pokestops 7 days in a row will now be rewarded with a random evolution item. The item can assist with evolving several in-game Pokemon, thus expanding players’ Pokedex.
Right now, the update is in the process of being rolled out for iOS and Android devices, so if you don’t see it immediately, give it a couple of hours to show up.
