Migrated primary API from Paper to Spigot for broader compatibility. The plugin remains fully compatible with Paper, Purpur and Folia through runtime detection and conditional code paths.

Build system:

• Replaced ktor fatJar with Shadow plugin (with HikariCP relocation)
• Replaced local JARs (PlaceholderAPI, Dynmap) with Maven dependencies
• Centralized all dependency versions in libs.versions.toml
• Updated CI workflow to gradle/actions/setup-gradle@v4
• Cleaned up unused plugins (application, paperweight)
• Updated Shadow plugin to 8.3.5 for Java 22 support

Bug fixes (GitHub issues):

• #90: Fixed BlueMap/Dynmap/Pl3xMap claims disappearing after reload/restart
• #86: Fixed NPE on /claim setname (null claim check)
• #85: Fixed Pl3xMap setLiveUpdate NoSuchMethodError (wrapped in try/catch)
• #77: Fixed elytra/piston bypass of enter protection (cancel event + disable gliding)
• #75: Fixed Folia PlayerPostRespawnEvent crash (use player scheduler directly)
• #74: Fixed HikariCP classpath conflict with LibertyBans (shadow relocation)
• #73: Added configurable opacity for Pl3xMap/Dynmap/BlueMap claim layers
• #67: Fixed wrong error message for unknown commands (show help instead)
• #58: Fixed mob spawning not blocked for Ghast, MagmaCube, Hoglin, etc.
• #57: Fixed wrong error message for ProtectedArea invalid characters
• #55: Fixed fly persisting after teleportation out of claim
• #48: Fixed player head names missing for Bedrock players (profile name fix)
• #47: Fixed MySQL TEXT column DEFAULT error
• #79: Added %description% placeholder to enter/leave messages

Performance & thread safety:

• Replaced all HashMap fields with ConcurrentHashMap where shared across threads
• Replaced 5 blocking .join() calls in event handlers with sync method
• Replaced 40+ stream().forEach() with direct forEach()
• Replaced parallelStream() on small collections with forEach()
• Fixed race condition in clearDataForPlayer (atomic remove pattern)
• Fixed resource leaks (HTTP connections, PreparedStatements)
• Added null checks on critical paths (CPlayer, Claim, API)
• Cached defaultValues lookups in claim loading loops
• Replaced Bukkit.getOfflinePlayer(name) with cached UUID lookups

API:

• Expanded SimpleClaimSystemAPI with 18 new methods
• Added async variants (CompletableFuture) for all blocking operations
• Added query methods: getPlayerClaimsCount, isClaimMember, isClaimBanned, etc.
• Added claim info methods: getClaimOwnerAt, getClaimNameAt, getAllChunksFromOwner
• Added validation methods: isAreaClaimFree, areChunksConnected, checkClaimPermission

Code quality:

• Added contextual logging to all catch blocks (no more bare printStackTrace)
• Removed all decorative comment blocks across 71 files
• Fixed incorrect javadocs (wrong param names, missing annotations)
• Updated .gitignore with IDE and OS file patterns
• Cleaned up Dockerfile (proper Adoptium URL, Ubuntu 24.04, temp cleanup)
• Modernized console startup banner with dynamic padding
• Updated LICENSE to standard MIT format

Config:

• Added dynmap-settings.claim-opacity (0.0-1.0)
• Added bluemap-settings.claim-opacity (hex alpha 00-FF)
• Added pl3xmap-settings.claim-opacity (0-255)
• Fixed explicit commit on claim insertion for DB safety
