ProMB v2.0.0 - The "Reborn" Update

We are incredibly excited to present ProMB v2.0.0. This is not just a standard update; it is a complete rewrite of the entire plugin from scratch. We listened to your feedback regarding version 1, analyzed the performance bottlenecks, and rebuilt the engine using a "Library-First" architecture.

Here is what has changed and why v2 is superior to v1:

1. Complete Core Rewrite & Optimization
In v1, the spawning system relied on a heavy global timer that could cause lag on larger servers.
In v2, we introduced the "Smart Grid Spawner." The plugin now divides the world into virtual grids and only processes calculations where players are actually active. All heavy lifting is done asynchronously, meaning zero impact on your server's TPS.

2. Full In-Game GUI Editor
Gone are the days of manually editing complex YAML configuration files and reloading the server to see changes.
v2 introduces a comprehensive GUI Editor. You can now:

• Create and Delete bosses via commands.
  
  
• Edit boss attributes (Health, Damage, Name) using chat inputs.
  
  
• Equip Vanilla bosses with armor and weapons directly from your own inventory.
  
  
• Select Vanilla entity types using a paginated GUI menu.
  
  
• Configure Loot Tables and Drop Chances visually.
  

3. Advanced Scheduling System
The simple interval timer from v1 has been replaced with a Real-Time Scheduler. You can now define exact spawn times down to the second (e.g., "FRIDAY:20:00:00" or "DAILY:15:30:00"). The system automatically calculates the next spawn time and handles server restarts seamlessly.

4. Region Leash System
We added a new Region Manager. You can now use the special "Region Wand" to define a 3D boundary (similar to WorldGuard). If a boss tries to leave this area, the new physics engine will smoothly push it back toward the center, ensuring your bosses never wander off or get stuck in unintended areas.

5. Better Integrations

• MythicMobs: We improved the hook. You can now toggle between Vanilla and MythicMobs entities directly within the Editor GUI.
  
  
• Database: Replaced the old flat-file system with HikariCP. ProMB now supports high-performance SQLite and MySQL connections with connection pooling.
  
  
• PlaceholderAPI: Added a full suite of placeholders for Timer, Status, Health, and Location (%promb_timer_id%, %promb_status_id%, etc.).
  

6. Quality of Life Improvements

• Added Tab Completion for all commands.
  
  
• Bosses now have dynamic health scaling options.
  
  
• Fixed issues where data would desync after a reload.
