XTransfer

Added

• Folia server support with global region scheduler
• Async file copy operations with buffered streams
• User cache loading from usercache.json
• Name-to-UUID mapping system for offline player lookup
• Backup file creation with configurable suffix
• Disk space checking before file operations (50MB reserve)
• File copy retry mechanism (3 retries with 1 second delay)
• Atomic file operations using temporary files
• Memory leak prevention with automatic lock cleanup system
• Periodic cache cleanup task (runs every hour)
• Player quit event listener to remove unused locks
• Last access time tracking for lock management
• Version detection fallback for unknown server versions
• Multi-language support with message placeholders
• Stats and advancements transfer with version detection
• List command for player data with pagination
• Tab completion with online and offline player support
• Player kick option for online target players

Changed

• Migrated to CompletableFuture for reliable async operations
• Optimized concurrent map operations with atomic replacements
• Improved UUID parsing with better error handling and formatting
• Enhanced scheduler with automatic Folia/Bukkit detection
• Simplified logging system while keeping debug functionality
• Better resource cleanup in onDisable() with timeout handling
• Streamlined configuration loading with auto-fix
• More efficient name-to-UUID mapping updates
• Optimized file copy with proper buffer sizing (8KB)
• Improved lock acquisition with timeout and deadlock prevention

Fixed

• Potential memory leak from unclosed player locks
• Thread safety issues in cache loading (added synchronization)
• Disk space exhaustion crashes during file transfer
• Server version detection crashes with unusual formats
• Concurrent modification issues in map operations
• File copy failures due to cross-filesystem moves
• Backup file corruption from incomplete writes
• Tab completion NPE with null permissions
• UUID format inconsistencies in user input
• Player kick timing issues with async operations
• Configuration loading errors with missing keys
• Resource leaks in file streams (try-with-resources)
• Shutdown hangs from unfinished tasks

Removed

• Redundant constant classes (merged into simple constants)
• Excessive logging methods (consolidated into core ones)
• Overly detailed debug outputs (kept essential only)
• Unnecessary map clearing operations
• Duplicate code blocks in transfer handling
• Deprecated Bukkit API usages
• Legacy version color formatting (simplified version display)
• Redundant permission checks in tab completion

Nah, this is a big work, honestly. Not gonna give up of it.
