UltimateShop

• Added new action: title, particle.
• When no economy plugin is detected in Vault, the plugin will repeat the detection to avoid the plugin failing to detect economy plugins linked to Vault due to different plugin startup sequences.
• Added placeholder support to some action options.
• Fixed PEconomy hook error message.

• Added not-open-when-invalid option support in buy more menu settings in config.yml file. If there is only a purchase button in the buy more menu and the product is not purchasable (meaning there is no buy price), then we consider this buy more menu to be invalid and cannot be opened, and the same applies to sell.
• Ignored double click in prefix GUI.
• The ItemFormat sell method is no longer case sensitive.
• Added hook item ID invalid catcher for MMOItems and CraftEngine plugin.

• Completely remaster the code of MySQL database feature.

Old version users need to reset the database to obtain the performance improvement brought by this update, otherwise the effect will be minimal.

• Removed sell.sell-all.hide-message and sell.sell-stick.hide-message option as they are not work anymore.
• Improved SellProductMethod.

• Fixed the issue where the normal Paper server would be recognized as a Folia server after Paper-1.21.8-Build # 53.
• Added /shop sellallhand command.
• Updated default example files.

• Added menu.secret-shop-items option in config.yml file.
• Updated example files for example shop and example daily shop, if you already generated them, try delete your UltiamteShop configs and they will auto regenerate new example files.
• Other small fixes and changes.
