Version 3.1.0 (February 25, 2026)

Added

• Mailbox Integration for Auctions: Items and revenues are now safely routed through the Mailbox system!
  • Cancelled Auctions: Instead of forcefully dropping returned items on the ground or cluttering the inventory, cancelling an auction now instantly sends the item to the Mailbox for asynchronous retrieval.
  • Auction Sales: When an item is bought, the revenue is sent to the seller's Mailbox as a distinct money notification instead of spontaneously appearing in the player's balance. Claiming the money notification within the Mailbox deposits the balance seamlessly and serves as a read receipt for the transaction.

Version 3.0.0 (February 25, 2026)

Major Changes

• Migrated to Cloud Command Framework (CCF): Rebuilt the entire command system for robust and native Paper command execution, including dynamic tab completions and strict argument parsing.
• Removed Legacy Support: Discontinued support for Minecraft versions 1.18 to 1.20 to fully standardize compatibility and features with the latest Paper 1.21 API.
• Modernized GUI Formatting: Fully integrated the Adventure Component API and MiniMessage formatting internally.

Fixed

• Fixed MiniMessage and Gradient Parsing Issues: Resolved bugs where MiniMessage and Hex gradients were explicitly stripped down to legacy ampersands, destroying formats in GUIs.
• Removed Default Minecraft Italicization: Removed forced default italics on GUI item names and lores across all PlayerAuctions menus. Let your configurations shine!
• Fixed My Listings GUI Blank Page Bug: Fixed a misapplied SQL offset argument that caused active items from an individual player to not load correctly within the player's personal listings interface.
• Resolved NoSuchMethodError for native component formatting caused by old Maven shade relocations on the Adventure API.
• Re-implemented the missing MiniMessage tag checking regex inside MessageParser to accurately detect Hex tags natively.

v2.5.2 - Critical Security & Stability Update

🛡️ CRITICAL SECURITY FIX

Patched Double Purchase Item Duplication Exploit

Fixed a critical vulnerability where multiple players could purchase the same auction item simultaneously, allowing item duplication and economic exploitation.

What Was Fixed:

• Multi-purchase exploit: Players could spam-click to buy the same auction item
• Seller overpayment: Sellers received multiple payments for a single item
• Item duplication: Buyers could duplicate items through concurrent purchases
• Economic instability: Server economy could be unfairly manipulated

Technical Changes:

• Implemented Atomic Reservation Pattern - items are reserved before currency transfer
• Added Optimistic Locking - prevents concurrent purchases with version checking
• Enhanced Automatic Rollback - auctions revert to ACTIVE status if transactions fail
• Improved Thread-Safe Operations - inventory operations moved to main thread
• Added Clear Error Feedback - users receive explicit messages for failed purchases

Update Recommendation: ⚠️ IMMEDIATE UPDATE REQUIRED - This fix addresses a severe game-breaking exploit.
