We are excited to announce the release of ChestLocked v1.3! This update focuses on expanding protection to new 1.21 to 1.21.11, introducing a smarter friend management system, and strengthening security against advanced griefing techniques with new administrative tools.

✨ What’s New in v1.3?
Auto-Cleanup & Maintenance (New!)

• 30-Day Auto-Expire: To keep your server clean, locks belonging to inactive players will now automatically expire after 30 days (Configurable).
  
  
• Self-Cleaning: Once a lock is expired, any player can break the container, or the next player to interact with it will automatically trigger the removal of the old protection.
  

️ Expanded Block Protection
You can now lock more functional blocks! We've added full support for:

• 1.21 Crafter: Keep your automation patterns and recipes safe!
  
  
• Lecterns: Prevent players from taking or swapping your books.
  
  
• Utility & Smelting: Brewing Stands, Furnaces, Smokers, Blast Furnaces, Droppers, Dispensers, and Barrels.
  

Proximity-Based Friend System

• Smart Search: The "Add Friend" menu now only shows players standing within a 20-block radius (Configurable).
  
  
• Anti-Lag & Secure: No more scrolling through hundreds of online names. Just have your teammate stand near you to grant them access!
  
  
• Distance Info: The GUI displays exactly how many blocks away each player is.
  

❌ New Friend Removal GUI

• Revoke Access: Added a dedicated Remove Friends menu (Red Dye icon).
  
  
• Easy Management: See a list of current friends on the sign and click their name to remove them instantly.
  

️ Security & Admin Features
⚡ New Admin Command: /chestlock unlockall [player]

• Mass Unlock: Admins can now remove every lock belonging to a specific player across all loaded chunks.
  
  
• Optimized Scanning: Uses an $X \rightarrow Z \rightarrow Y$ scan pattern to ensure zero server lag during the process.
  
  
• Usage: /chestlock unlockall <PlayerName> (Requires chestlock.admin).
  

Ultimate Hopper Protection (Siphon-Proof)

• Anti-Theft: Strict logic prevents Hoppers and Hopper-Minecarts from siphoning items out of any locked container.
  
  
• Solid Security: Even if a player places a hopper below your chest, your items stay exactly where they are.
  

System Highlights

• Update Checker: Admins will receive a notification upon joining if a new version is available on SpigotMC.
  
  
• Strict GUI Access: Only the Owner or an Admin can access the Shift + Right-Click Management Menu.
  
  
• Zero Database: Ultra-lightweight performance; all data is stored directly on the sign metadata.
