Pokémon Go update, adds Buddy Pokémon (Also Niantic tries to block rooted devices)

Changelog

• Implemented Buddy Pokémon: Trainers will now be able to choose one of their Pokémon to be their buddy. A Trainer can earn Candy for their Buddy Pokémon by walking a certain distance.
• Made it easier to select smaller Pokémon on the screen.
• Fixed an issue where Eggs would sometimes hatch without displaying the animation.
• Improved performance reliability when a device switches networks to no longer cause the application to hang or stop updating.
• Pokémon GO Plus support
• Minor text fixes.

"We continue to focus on eliminating bots and scrapers from Pokémon GO. Rooted or jailbroken devices are not supported by Pokémon GO. Remember to download Pokémon GO from the official Google Play Store or iTunes App Store only."
