UPDATED:

• Fixed support for Custom Model Data on capsule and spawn eggs (now entered as a string).
• Added Custom Model Data capsule validity check (like name and lore checks).
• Changed "item-cost" check to allow both 'none' or an empty value to disable per mob.
• Reworked how sounds are handled through the plugin (hopefully fixing any previous issues some people were having).
• Updated MobsToEggs spawn egg spawn cancelling when clicking on blocks that have an interact option (like a check or furnace).
• Made edits to default config.yml wording to add more clarity.
• Fixed inventory holding entities not having inventory/items held/armor saved.
• Fixed potion effects not being saved to entities.
• Added 1.21.6+ support with happy ghast (new data-tag for happy ghasts).
• Changed capsule "item" value to support being empty.
• Fixed extra '}' added at the end of the plugin update message in console.
• Updated to Kotlin 2.2.0.
• Updated internal dependancies.
• Changed MobsToEggs spawn egg spawning to better mimic a vanilla spawn egg.
• Fixed spawners not changing the spawner type if the spawn egg item is not a mob spawn egg.
• Added an auto config updater to auto update default sound values in the config.yml (values updated in 1.7.16).
• Fixed bug with mob egg material value throwing an error if the material name wasn't uppercase.
• Fixed cat variants throwing an error if another plugin/datapack added new variants.
