PlayGuardian is your ultimate server protection companion. With v3.4.1, we’ve introduced a suite of powerful new features designed to maximize server security, performance, and overall functionality. This update enhances server monitoring, improves automatic notifications, and optimizes resource management. We've also addressed several bugs, ensuring that PlayGuardian runs smoothly and efficiently for both administrators and players alike.

New Features Added:

1. Server Performance Monitoring:
   • System Health Display: Now you can monitor real-time data on your server's performance, including TPS (Ticks Per Second) and Memory Usage. Admins will be alerted if performance drops below optimal levels.
   • Memory & TPS Warnings: When memory usage exceeds 80% of allocated memory or TPS drops below 18.0, PlayGuardian will issue warnings, allowing you to take action before performance degrades.
2. Automatic Update Notifications:
   • Version Check: PlayGuardian now automatically checks for updates from SpigotMC and notifies server administrators when a new version is available. This keeps your server up to date with the latest features and fixes.
   • Auto-Download Option: Optionally, PlayGuardian can download the latest update automatically, install it, and even attempt a server restart to apply the update seamlessly.
3. Advanced Server Access Protection:
   1. Backend IP & Whitelist Support:
      • IP Whitelisting: PlayGuardian allows you to tightly control which IPs can access your server by specifying trusted backend IPs. This ensures that only authorized services, such as your server's administrative tools or back-end systems, can connect to your server, blocking any unwanted or malicious connections that may attempt to bypass security.
   2. Geo-Blocking & Proxy Detection:
      • Geo-Blocking: With PlayGuardian’s built-in geo-blocking feature, you can restrict players based on their geographical location, ensuring that players from specific regions (e.g., known bad regions) are prevented from accessing your server. This is especially useful in preventing attacks or unwanted traffic from certain parts of the world.
      • Proxy Detection: PlayGuardian detects and blocks connections that are coming through proxies, ensuring that only legitimate players can connect to your server. By identifying suspicious proxy traffic, you can avoid fraudulent or malicious activity like bot attacks or VPN usage.
   3. Anti-VPN Protection:
      • VPN Detection: New in PlayGuardian is Anti-VPN Protection, which automatically identifies and blocks players who are attempting to connect to your server using a VPN (Virtual Private Network). This feature works in tandem with Proxy Detection, ensuring that users cannot bypass geo-blocking or security measures by hiding their true IP addresses behind a VPN.
      • Enhanced Protection Against Malicious Users: This feature enhances security by preventing players from masking their location to bypass region-based bans or engage in other malicious activities. It ensures that only players with valid, traceable IP addresses can join your server, providing a much stronger defense against cheaters and hackers.
   • Geo-Blocking & Proxy Detection: Protect your server by blocking connections based on geographic location or detecting proxy usage, ensuring that only legitimate players can join.
4. AFK Detection & Player Kick Feature:
   • Enhanced AFK Detection: Our improved AFK system automatically kicks inactive players after a configurable time, helping keep your player base fresh and server performance at its peak.

New Functionalities:

1. Automatic Resource Cleanup:
   • PlayGuardian now ensures that all resources (database connections, file streams, and scheduled tasks) are automatically cleaned up upon shutdown. This prevents resource leaks and ensures that no lingering processes affect server performance after restarts or stops.
2. Server Health Alerts:
   • In addition to displaying server health data, PlayGuardian can now send health alerts to administrators via Discord Webhooks or other custom alert systems. Stay informed about potential issues with real-time notifications.
3. Enhanced Chat Filtering:
   • A new ChatFilterListener has been added to allow administrators to monitor and filter inappropriate or unwanted language in the chat. This feature can be easily customized to suit the specific needs of your server.

Bug Fixes:

1. Fixed Update Check Logic:
   • Resolved an issue where PlayGuardian sometimes failed to check for new updates. The version-checking mechanism has been optimized to ensure reliable performance and timely notifications of updates.
2. Memory Leak Fixes:
   • Fixed several memory leak issues, particularly when PlayGuardian interacted with external services like databases and network connections. This update ensures a more stable and efficient server environment.
3. Server Access Protection Improvements:
   • Addressed bugs where the ServerAccessProtection feature wasn’t correctly recognizing some backend IPs. The IP whitelist and blacklist now function as expected, improving the security and reliability of server access control.
4. AFK Kick Timer Accuracy:
   • Corrected a bug that sometimes prevented the AFK timer from triggering after the designated period. The feature now reliably kicks idle players after the specified timeout, ensuring fair gameplay for everyone.
