Although the Pokémon GO update was yesterday, the new gyms are now up and running as of today.
There has been changes added to the way Gyms work in Pokémon GO, such as now being able to obtain items from them, and a new Gym badge feature.
Here’s the breakdown from Niantic regarding the new Gym update:
“New Gym Features and Updates: Starting soon, Gyms are undergoing a major facelift. You’ll soon be able to spin the Photo Disc at Gyms to acquire items just as you do at PokéStops—but that’s only the beginning. More updates to Gym battles are also just around the corner. Gyms are no longer based on Prestige and training. Instead, they now feature six permanent slots that can be filled by the controlling team’s Pokémon. Each Pokémon assigned to these slots must be unique. For example, only one Blissey can be assigned to a Gym at a time. In addition, opposing teams will battle the Pokémon in the order they were assigned to the Gym.
At the heart of the update is a new motivation system that will significantly change how you interact with Gyms. When a Pokémon is assigned to a Gym, a motivation meter will be displayed. Pokémon assigned to defend a Gym lose motivation over time and as they are defeated in battle. As a Pokémon loses motivation, its CP will temporarily decrease, making it easier for opposing teams to defeat. To help keep the Pokémon motivated and in tip-top shape for their next battle, Trainers can treat their team’s Pokémon to some Berries, which restore their motivation. If a Pokémon loses all motivation, it will leave the Gym and return to its Trainer the next time it loses a battle, so you’ll want to keep your team’s Pokémon motivated by giving them Berries frequently!
Gym Badges: Now you’ll be able to earn Gym Badges when interacting with the many Gyms around the world. Gym Badges serve as mementos of your Pokémon GO adventures and reflect your contribution to a Gym’s success.
You’ll be able to level up your Badges by battling, giving Berries to the Pokémon in the Gym and spinning the Gym’s Photo Disc. You can earn the opportunity to receive bonus items and increased rewards from Gyms by raising the level of your Gym Badge.”
