AuctionHouse v1.1.3 — Hotfix

Bug Fixes

- Fixed harmless "Duplicate column/key name" warning spam on every restart with MySQL

v1.1.2 Changelog Bug Fixes - Fixed AuctionHouse failing to load on Folia servers — the plugin is now correctly marked as Folia-compatible

v1.1.1 Changelog Compatibility - Restored backwards compatibility with Paper 1.21.x and Java 21 - Still loads cleanly on Paper 26.1+ with Java 25 — one build works on both Bug Fixes - Update checker now compares versions semantically instead of by string equality (no more "new version available" when you're already on a newer build) - Update checker safely ignores garbage / outage responses from SpigotMC - Fixed a build issue where plugin.yml versions could lag behind the actual release Improvements - config.yml now self-heals on startup — keys added in newer plugin versions are automatically merged into older configs. Fixes "admin GUI toggle doesn't save" symptoms caused by stale configs missing newer keys (e.g. modules.buyorders on configs pre-dating the Buy Orders feature)

v1.1.0 Changelog Compatibility - Updated to support Paper 26.1+ (Minecraft 26.1.2 and later) - Now requires Java 25 — matches the new Paper server runtime Note - Stay on the previous version if you're running Paper 1.21.x or Java 21

v1.0.4 Changelog Bug Fixes - Fixed a race condition where expired auctions could be delivered to both the buyer and returned to the seller's mailbox under high load - Fixed memory leak: GUI click cooldowns were never cleared, accumulating one entry per unique player forever - Fixed memory leak: mailbox cache was retained for offline players indefinitely - Fixed memory leak: transaction lock map could grow unbounded if cleanup was missed on exception paths - Async-wrapped seller info GUI back button — no longer blocks the main thread on a database query Compatibility - Now works on Spigot 1.20+ (previously Paper-only) — runtime detection automatically uses the right serialization format - Backwards-compatible item storage — existing databases work without migration on either platform - Folia and Purpur still fully supported Improvements - Added background sweep task that removes idle transaction locks every 5 minutes - Removed unused legacy code paths to reduce footprint - Added 9 new automated stress tests covering memory leaks, lock contention, and concurrent load (106 total tests)
