## New
* Added v1.21.5 support (yes, v1.21.4 still works)
* Splash potions will now work on turrets!
* Added automatic support for GUI template files.
* Added command tab completion for `/k admin cmd` and `/k help`.
* Add sub-commands section for `/k admin cmd`.
* Added tab completion for `/k admin searchConfig`.
* The `default-flags` option in `config.yml` now has a more organized format.
* **[EngineHub]** Added possible support for FastAsyncWorldEdit (and possibly AsyncWorldEdit?) This will not work by default with the default schematics due to a bug/incompatibility with normal WorldEdit with how block rotations are handled. You will need to create your schematics from scratch.
* **[EngineHub]** Added an option to forcefully rename all saved schematic with a given extension.
* **[EngineHub]** Added an option to save schematics with a different format.
* **[EngineHub]** `/k admin schematic list` will now show more details about schematics and the message is customizable.

## Fix
* Fixed issues relating to auto config reloads caused by the previous version.
* Updated all addons for the latest KingdomsX core compatibility.
* Fixed players being able to join kingdoms without an invitation.
* Fixed a rare error during server shutdown.
* Fixed an issue where two buildings that would conflict could be placed next to each other that when the previous building was not fully built.
* Fixed redstone mechanics (levers, buttons, etc.) being able to affect protection blocks with signs.
* Removed the plugin's prefix (when enabled) in certain messages that were unnecessary.
* Protection sign GUI will now close automatically if the sign is broken.
* Fixed an error caused by using `/k admin searchConfig` without a file filter.
* Fixed disallowed color description in `color-picker.yml` by default.
* Fixed `/k help` footer message ignoring the player's language settings.
* Fixed sculk catalysts spreading in protected lands. (It still works if the catalyst is inside your own land.)
* Fixed an error on server startup for some older versions. (This didn't really affect the plugin's functionality)
* Fixed an issue where commands that contained colons `:` in configs didn't properly get parsed.
* Fixed a few data conversion issues when converting MySQL, MariaDB and PostgreSQL databases.
* Fixed the "flag" button on national nexus by default (you'd need to delete the GUI config to fix this)
* Fixed where cancelling flag/banner and player selector (for protection sign) would not return to the GUI.
* Fixed `/k admin FSCK` erroring when fixing pacifism state for kingdoms.
* Fixed MythicMobs support for newer versions.
* Fixed `/k book open <chapter>` even though I know most people don't even know this feature exists or care for it.
* Finally fixed the godforsaken inferno turret visuals. (Might not work in older versions)
* **[Map Viewers]** Fixed nation zoom level and popup style by default (You need to reset `maps/nations.yml` for this to work.)
* **[EngineHub]** Now uses the preferred file extension when saving schematics.
* **[EngineHub]** Fixed `/k admin schematic convertall`

## Others
* Slight performance improvement for reading config values.
* More GUI configs are now using literal scalar style for lore tags by default, making them easier to configure.
* Added a description under powercell structures for pacifist kingdoms to warn them about the usefulness of the structure.
* The plugin will now warn about possible corrupted building missing blocks.
* Data conversion will now prevent you from starting the server again if it fails. You'd have to manually follow its instructions to unlock the plugin.
* Improved server reload protection.
* **[EngineHub]** Removed other EngineHub related settings from buildings.yml by default (`schematic` option) which is also handled by `/k admin schematic setup`
