📦 ChestLogger v2.7.0 (Paper)

🌟 Highlights

• Multi-Version Support: First-class release support for both Paper 26.3 and Paper 26.2.
• Double Chest Logging Overhaul: Zero-duplication transaction tracking across 54-slot inventories.
• Unified Double Chest Audit Merging: Inspecting either half displays the complete, merged history of both container blocks.

🚀 What's New & Changed in Paper

1. Paper 26.3 & 26.2 Dual Releases

We now provide dedicated SemVer 2.0 build-metadata JARs for Paper server administrators:

• chestlogger-paper-2.7.0+26.3.jar — Built against Paper API 26.3
• chestlogger-paper-2.7.0+26.2.jar — Built against Paper API 26.2

2. Double Chest Transaction Deduplication

• Resolved Issue: Player deposits, withdrawals, and hopper transfers in double chests were occasionally logged twice due to Bukkit event propagation across combined inventories.
• Fix: Updated PaperChestEventListener with coordinate half-partitioning. Deltas occurring in slots 0–26 are assigned strictly to the primary block location, while slots 27–53 are routed to the linked partner block.

3. Unified Historical Log Merging

• Resolved Issue: When single chests were combined into a double chest, older logs from one side were excluded when inspecting the other side.
• Fix: /chestlog inspect, the Inspection Wand, and the in-game viewer now dynamically resolve connected double chest halves via DoubleChest block states and fetch unified transaction history across both coordinates in a single query.

4. Engine & Performance Stability

• Zero Server Tick Impact: Lock-free MPSC ring buffer processing up to 65,536 events with LZ4 block compression on background worker threads.
• Pure Bukkit Architecture: Zero NMS (net.minecraft.server) dependencies ensures clean compatibility across server builds.
• Self-Healing Storage: Tail recovery engine automatically repairs incomplete or truncated write boundaries on abrupt server shutdowns.

📋 Requirements & Upgrading

• Java: Java 25 JRE/JDK required.
• Server Platform: Paper 1.21.x - 26.2.
• In-Place Upgrade: 100% backward compatible with existing v2.6.x logs (logs/*.clog) and indexes (index/*.idx). Simply replace the JAR in your plugins/ directory and restart.
