v6.3.0

Paper API Update

• Updated to Paper API 26.1.2 (Minecraft 1.21.4+, stable release).

Folia Support

• Folia-compatible — Replaced all Bukkit.getScheduler() calls with Folia-aware scheduling via SchedulerUtil.
  • Player operations (kick, sendMessage) use player.getScheduler().run() (entity region thread).
  • Global sync tasks use Bukkit.getGlobalRegionScheduler().run().
  • Async timers use Bukkit.getAsyncScheduler().runAtFixedRate() with millisecond conversion.
• New utility — SchedulerUtil.java provides a clean, unified API across Paper and Folia.
• plugin.yml — Added folia-supported: true.

Removed

• LocaleManager — Dead code: per-player locale resolution was never actually called. Message delivery already goes through Settings.Messages and lang/messages_*.yml.
• AuditLogger — Dead code: auditLogger.log() was never invoked anywhere.
• In-Game GUI — Entire gui/ package removed (~500 lines). Administrators primarily use config.yml directly.
• UpdateChecker — Removed GitHub API version check. Update manually via GitHub Releases.
• /al gui / /al update / /al export / /al import / /al kickall — Removed rarely-used subcommands and their helper methods.

Simplified

• StatsTracker — Replaced YAML persistence + batched saves + retention cleanup with pure in-memory AtomicInteger counters. Zero disk I/O.
• config.yml — Removed stats.record_retention_days and stats.stats_retention_days (no longer applicable).

Documentation

• README, wiki/, docs/ updated to reflect all removals and simplifications.

Full Changelog: 6.1.0...v6.3.0

v6.1.0

Removed

• Web Dashboard — Removed built-in HTTP server (DashboardServer). Use external monitoring tools instead.
• Auto Build / GitHub Auto-Download — Removed AutoBuildManager. Update manually via GitHub Releases.
• Prometheus Metrics — Removed /api/metrics endpoint (was part of Web Dashboard).

Paper API Update

• Updated to Paper API 1.21.11-R0.1-SNAPSHOT (Minecraft 1.21.11+).

Performance Optimizations

• StatsTracker — Batch write every 30s instead of disk I/O per detection.
• DetectionLogger — Memory queue + batch write every 10s (was sync flush per line).
• AuditLogger — Memory queue + batch write every 10s (was auto-flush per line).
• PlacementGuard — Config caching, staffNotify UUID cache, Location reuse, sliding ratio 80% for consecutive same-type detection, pitch tolerance 0.1°.
• ProtocolLibBridge — Signal config cached at start, EasyPlace consecutive tracking (3 hits / 10s window), NBT query detail extraction (TX ID, block position).
• CommandGuard — StaffNotify UUID cache (replaces Bukkit.getOnlinePlayers() iteration).
• GraduatedPunisher — DiscordWebhook instance cached, staffNotify UUID cache.
• Punisher — God method decomposed into 10+ focused methods.
• TokenBucket — Removed redundant synchronized (Bukkit main thread is single-threaded).
• DynamicThresholdManager — Config values cached on reload, not read per-tick.

Detection Improvements

• ModChannelDetector — Pre-registers known Litematica channels (litematica:main, litematica:hello, litematica:place) for passive monitoring beyond config list. Channel name resolution for readable logs. Detection cooldown (5s per player). Better servux payload depth inspection.
• ProtocolLibBridge — Consecutive EasyPlace hit tracking to reduce false positives. Servux metadata detection for packets without version string. NBT query inspection includes transaction ID and coordinates.
• PlacementGuard — Consecutive same-type uses sliding ratio (80%) instead of requiring all placements to match. NoLookChange pitch tolerance relaxed to 0.1° (yaw remains 0.05°).

Configuration

• Config.yml rewritten with concise Chinese descriptions, reduced from 310 to 130 lines.

Documentation

• README, wiki/, docs/ updated to reflect all changes.

Full Changelog: 5.0.0...6.0.0

v5.0.0

✨ New Features

• Auto Update Checker — Automatically checks GitHub for new releases on startup. Admins are notified on join when an update is available. Manual check via /al update.
• Violation Whitelist — Whitelist trusted players to only log detections without punishment. Three modes supported via config.yml (whitelist section). Manage in-game with /al whitelist add|remove|list.

  • Violation records viewer with clear action
  • Quick settings toggles (detection, anti-printer, webhook)
  • Multi-language UI: 简体中文 / English / 繁體中文

🔧 Improvements

• Standard Maven Project Layout — Source files moved from top/ to src/main/java/top/, resources moved to src/main/resources/, removed custom <sourceDirectory> from pom.xml.
• Locale-Aware Messages — Added locale config option (zh_CN / en_US / zh_TW). Plugin loads messages_{locale}.yml with fallback to messages.yml.
• GitHub Repository — Updated update checker URL to ALingqing/AntiLitematica.

🐛 Bug Fixes

• Shade Plugin Warning — Excluded META-INF/MANIFEST.MF from bstats shaded JARs to eliminate resource overlap warnings.

📦 Dependency Changes

• No new dependencies added. Web dashboard uses JDK built-in com.sun.net.httpserver.HttpServer.

4.3.0

Please delete old configuration files before updating, old configs are incompatible with this version AntiLitematica 4.3.0 - AntiLitematica

Fix high false positive rates in PlacementGuard Convert GUI to single-page 54-slot inventory Remove gray glass from rows 1-5, keep only GrimAC Optimize GUI display text for zh_cn and en Fix block disappearance for Bedrock players (Geyser+Floodgate API, multi-threading) GUI reorganization with gray glass fillers Create 12 language files (zh_CN, en, zh_TW, fr, de, ja, ko, ru, es, pt, ar, vi) Redesign GUI according to user's detailed specification (detection settings, punishment, anti-cheat, anti-printer, webhook+dynamic+language, system settings)

4.2.1

Reduced false positives by relaxing printer detection thresholds, made single placement warnings non-blocking, improved command burst tolerance, and kept repeated suspicious behavior detectable for real offenders.

4.1.1

Fixed an error caused by graduated punishments directly kicking/banning players in ProtocolLib async packet listening.
Punishment actions are now properly scheduled to run on the main thread, compatible with Paper/Spigot async safety checks.
