SimpleSMP – Version 2.0 Changelog

Release Date: 2026-03-16

New Features

• GUI System: Fully-featured, multi-page GUI builder with clickable buttons, automatic drag and shift-click protection, and customizable layouts.

• Player Heads Enhanced: Player heads now display extended information such as UUID, online status, world, gamemode, level, and total playtime.

• Multi-language Support: Added messages_*.yml system with configurable language in config.yml (currently English and German supported).

• Fly Command Enhancements: Refactored /fly command with toggle logic separated, optional fly speed, and improved messaging via centralized SendMessage utility.

• Centralized Messaging: All plugin messages now use SendMessage and MessageManager for color formatting, prefixes, and multi-language support.

Improvements

• Command Structure Refactor: Clean separation of command handling and logic for better maintainability.

• Inventory Protection: GUI now blocks shift-click, number-key swap, double-click, offhand swap, and dragging to prevent item duplication or GUI breaking.

• Code Organization: Utilities and managers reorganized for scalability, including GUIBuilder, ToggleFly, and SendMessage.

• User Experience: Improved player feedback messages, prefix consistency, and color formatting for success, error, and info messages.

Bug Fixes

• Fixed buttons in GUIs not responding due to missing InventoryHolder assignment.

• Corrected player head item meta for online/offline players.

• Prevented console errors when using /fly without specifying a target.

Developer Notes

• All GUIs now use GUIPage as InventoryHolder for proper event handling.

• Placeholder support and automated page navigation can be easily extended in the GUI system.

• Messaging system allows future addition of English/German or other languages with minimal code changes.
