Niantic has updated Pokemon Go APK to v0.41.4 with minor updates from 0.41.3 within a day.
For 0.41.1 update which is included with 0.41.4, Niantic has added catch bonus for trainers for specific types of Pokemon. Basically the more of the same type you catch, more bonus rewarded. Gym training has also been updated so trainers can bring up to 6 Pokemons to battle just like the real Pokemon Go show. CP of Pokemon that you are battling may be temporarily adjusted lower for the training session.
