There have been two changes done at the same time. More Pokemon from Sinnoh have been released and they've been added into this calculator.
There has been a rebalance in Raids and Trainer battles.
- Raid bosses tier 3-5 have increased HP.
- Move stats have changed, only for Trainer battles
- A few Pokemon have new moves added.
The calculator has been updated, as well as the android app. There will be a post soon about what new Pokemon might be useful.
