Added

• Multiverse Support - Automatically detects Multiverse-Core and displays world aliases
• Per-World Settings - Configure each world independently with its own settings
• World Settings GUI - New menu to browse and configure all worlds
• World Edit Menu - Adjust radius, max chunks, safety radius, priority per world
• Heat Map Persistence - Chunk heat data now saves across restarts

Improved

• Smart Unloading - Now respects per-world settings and priorities
• Maintenance Mode - Properly respects manual on/off state, won't auto-toggle when manually set
• Race Condition Fix - Chunk unloading now waits for completion before reporting count
• Memory Management - Better GC handling with configurable thresholds
• GUI Cooldown - Reduced click spam issues

Fixed

• Maintenance mode staying off when manually disabled
• Duplicate chunk tracking causing memory bloat
• Smart unloader returning incorrect counts
• Memory threshold errors on some systems

Added

• 1.20 to 1.21+ support
• Java 17
• Paper & Spigot compatible
• Faster async chunk loading on Paper
• GUI menu (/cm)

Improved

• Memory management
• Chunk prediction
• Performance optimizations
• Updated dependencies

Bug Fixes:

• Fixed: Thread pool crash when adjusting core thread count
• Fixed: Server freezes caused by indefinite chunk analysis operations
• Fixed: NaN heat values breaking the smart chunk unloader
• Fixed: Cache inconsistency preventing proper chunk cleanup

Performance Improvements:

• Improved: Memory leak from unused return values in batch operations
• Improved: Overall plugin stability and resource management

Bug Fixes:

• Fixed "Comparison method violates its general contract" error when players disconnect
• Improved chunk unloading stability
• Fixed ANSI color codes in console (reverted to avoid Bukkit warnings)

Improvements:

• Better memory cleanup on player disconnect

Bug Fixes

• Fixed critical sorting issue that caused IllegalArgumentException: Comparison method violates its general contract! during chunk unloading operations
• The smart chunk unloader now captures heat values before sorting to ensure comparison consistency
• This prevents crashes that could occur when the server was processing chunk unload tasks

Details

• Resolved race condition in SmartChunkUnloader.identifyColdChunks() where volatile heat values could change during sort operations
• Improved stability of chunk management system under high load conditions
