+- Added a Mixin for the BrewingStandScreenHandler to fix the incorrect handling of quickMove in Fabric.
+- Corrections to the ability implementation have been made that make ``Ability.forced`` function as intended and never reroll an ability for a Pokémon, please check your implementations to ensure the corrected behavior is intended for your use case.
+- ``Pokemon.ability`` no longer has a public setter, please migrate to using ``Pokemon#updateAbility``, this handles the ability coordinate storage for you when necessary.
+- ``Ability.forced``, ``Ability.index`` and ``Ability.priority`` have all had their setters internalized, there is no longer any need to manually adjust these migrate to the method mentioned above to handle that process for you.
