1.1.0 (1.21)

New Features

Horse disguise now can make players step on one-block height
Added toggle to switch if flying in fluids is allowed
- This can nerf some behavior, like mining Ancient Debris in lava in the Nether
Add permissions for abilities
- Now every ability from a disguise will have a matching permission node.
- The node format is xiamomc.morph.ability.<DisguiseID>.<AbilityID>
  - For example, the Night Vision ability for Enderman disguise is xiamomc.morph.ability.minecraft.enderman.morph.night_vision
- Because the permission check has a high performance impact, we added an option to disable it. You can disable this feature through the config file or using the /fm option ability_check_permissions command to toggle.
