[PlayerDataSync-26.3.4-SNAPSHOT] - 2026-03-11

🔧 Fixed & Improved

• Legacy Minecraft Support (1.8-1.16): Resolved multiple critical issues for older server versions.
• Java 8 Compatibility: Fixed NoSuchMethodError: String.isBlank() by replacing it with Java 8 compatible alternatives in MessageManager.
• FastStats Isolation: Isolated Java 17-dependent metrics library to prevent UnsupportedClassVersionError on Java 8 environments.
• JDBC Driver Fixes:
  • Implemented explicit driver registration to solve "No suitable driver found" errors in shaded environments (PaperSpigot 1.8.8).
  • Fixed AbstractMethodError: Connection.isValid() by adding safety wrappers for legacy JDBC drivers (SQLite).
• Configuration Robustness:
  • Fixed an issue where config.yml was being stripped of content and comments on older Bukkit versions by reducing unnecessary saves.
  • Implemented explicit UTF-8 loading for configuration files to prevent character encoding issues on Windows servers.
  • Enhanced configuration migration and initialization to correctly merge defaults without overwriting existing user settings.
• Stability and Performance:
  • Fixed a race condition where default configurations were not being saved to disk before being reloaded during the first startup.
  • Consolidated maintenance mode and version checking logs for better readability.

[PlayerDataSync-26.3.3-SNAPSHOT] - 2026-03-10

🚀 New Features

• Maintenance Mode: Pause all data syncing with /sync maintenance <on|off>. Useful for database migrations or emergency fixes.
• Management GUI: Use /sync menu for a visual way to toggle sync options and manage the plugin.
• Performance Profiler: Use /sync profile to track average and maximum save/load times for better performance monitoring.

🔧 Fixed

• Java Compatibility: Downgraded default Java target to Java 8 to ensure full compatibility with Minecraft 1.8.8 through 1.16.5 (Purpur) and resolved "Unsupported class file major version 65" errors.
• Build Configuration: Removed conflicting activeByDefault profile to prevent accidental Java 21 builds.

🔄 Update Checker

• Hardcoded API Key: Added a hardcoded API key (CSP-PDS-...) for streamlined server-to-API authentication.
• Improved Caching: Implemented a 1-hour cache for update metadata to reduce unnecessary API requests.
• Manual Check Command: Added /sync checkupdate command to manually trigger an update check (bypasses cache).
• Silent Reloading: Added simplified version check handling that can be called asynchronously without blocking the main thread.
