After a long time, the plugin has been finally updated to support all Minecraft versions from 1.19.4 to 1.21.11. This update also brings entity displays (show any mob, such as a zombie) and reworks how displays work, since now you can modify base entity settings too (such as being on fire, custom display name, etc). Other than that, many fixes and improvements have been implemented, such as:

• Folia support
• New particle action, fixes and cooldown setting.
• Switch Adventure from Bungee to Bukkit platform.
• Add more item meta options.
• Add per-player pages for Text Displays (see new subcommands here)
• Head caching system (loads them on enable or reload to prevent excessive requests)
• Add moveto subcommand.
• Update project dependencies.
• Support for 1.21.4+ custom model data components (see customModelData here for more info)
• Improvements to GUI system and inventory handling.
• Many bug fixes.

Some plans for future updates are:

• In-game editor for actions.
• Multiline displays (a display with text and items, for example)
• Animated item and block displays
• Entity metadata system (modify what entities in Entity Displays look like, such as wolf variant)

*If you are migrating from previous versions, you will need to use the "/ad convert" command. CREATE A BACKUP OF YOUR DISPLAYS FOLDER BEFORE CONVERTING! More information on this command here.

I have tested this plugin on Paper 1.21.11 although I may have missed some bugs. If you encounter any, please report it on GitHub or Discord, not on the reviews section.
