Added:

• #128 BattleInstance: Associates a TrainerNPC with a PokemonBattle and the LivingEntity it was attached to at the start of that battle
• #127 TrainerNPC#getBattleInstances(): Retrieves a list of all active BattleInstances the trainer is attending to

Changed:

• #126 Adjustments to the battle AI switch evaluation, which makes it less likely for trainers to switch into pokemon with much higher stats
• #125 Slight adjustment to battle AI to lower the chance to use (often waste) healing items on squishy pokemon on the field
• #124 Trainers may now attend to multiple battles at the same time
• Note that a trainer entity can still only attend to one battle at a time (a copy of that entity can attend to a different battle)
• The entity the trainer was attached to at the start of a battle is stored to ensure recall animations of pokemon will always point towards that entity
• This was possible in an older version of the API (with unexpected side effects) but was never an intended feature, now it is
• #123 Trainers now support custom sound events. Use the battleTheme property to assign a custom resource location (falls back to battle.pvn.default if unset). Refer to the docs for more info

Fixed:

• #122 Battle AI attempting to use baton pass when there is no pokemon to switch to and it will also avoid that move if the user has no stat buffs
• #121 Battle AI not including active shield effects (light screen/reflect) in some damage calculations
• #120 Battle AI not recognizing the weather effects "heavy rain", "extremely harsh sunlight" and "strong winds" (e.g. attempting to use fire or water moves when they would fail)
• #119 BATTLE_STARTED event receiving null instead of the BattleState as parameter

• #82 Fixed dyna- and gmax failing for some status moves

For example: Pokemon fainting at the end of a turn on both sides (e.g. by moves like "Perish Song") and the player chosing a pokemon to switch very quickly. Note that these changes are mostly limited to battles started by this api for now (it is currently unclear if these kind of issues also occur in other types of battles like PvP).
