Changelog

[1.0.17] - 2026-08-02

Performance

• Spatial index for getRegionAt() and checkCollision() — O(1) amortized lookups instead of O(n) linear scan
• Optimized loadAllRegionsSync() — 3 queries with batch loading instead of 2N+1 individual queries
• Fixed race condition on idMap — changed from HashMap to ConcurrentHashMap
• SQLite PRAGMA foreign_keys moved to HikariCP connectionInitSql — no longer executes on every getConnection()

Architecture

• Extracted SchemaManager class — eliminates ~200 lines of duplicated table creation logic between MySQL and SQLite
• Consolidated sendAccessDenied / sendAccessDeniedCooldown into single method in ProtectionListener
• Unified saveMemberSync / saveMemberAsync logic into shared executeSaveMember in ProtectionDao
• Added Builder pattern to ProtectionRegion (existing constructors preserved for compatibility)

Changed

• ProtectionManager now uses MessageUtils.parse() singleton instead of inline MiniMessage.miniMessage().deserialize()
• getAdjacentRegions() and mergeRegions() now use spatial index instead of scanning all world regions
• Removed @Deprecated isAllowed() method from ProtectionRegion
• Removed @SuppressWarnings("unused") from AdminProtectionCommand
• Removed redundant null checks in ProtectionListener event handlers
• Hardcoded Spanish fallback strings replaced with English in AdminProtectionCommand

Fixed

• Fixed SQLite syntax error with AUTOINCREMENT keyword order in SchemaManager
