## Version 2.0.0 ### Bug Fixes - **Fixed version mismatch** - Synchronized `pom.xml` version with `plugin.yml` (both now 2.0.0) - **Fixed unused variable** - Removed unused `materialName` variable in `RedstoneListener` - **Fixed stats command** - `/arl stats` now shows real statistics from `CounterManager` instead of hardcoded zeros - **Fixed unused imports** - Removed unused imports from `CommandHandler` and `RedstoneListener` - **Fixed potential NPE** - Added null check for `location.getWorld()` in `CounterManager.sendAlert()` to prevent crashes with unloaded chunks - **Fixed event priority** - Changed from `MONITOR` to `LOW` priority since we modify block state - **Fixed log download** - `/arl logs download` now shows log file info (name, size, path, modified date) ### Optimizations - **Thread-safe counters** - Replaced `HashMap` with `ConcurrentHashMap` and `AtomicInteger` for thread safety - **Memory-efficient keys** - Using String keys instead of `Chunk`/`Location` objects to prevent memory leaks - **Extracted time constants** - Magic numbers replaced with named constants (`TICKS_PER_HOUR`, `TICKS_PER_DAY`, `DAY_MS`, `ALERT_COOLDOWN_MS`, `BATCH_SIZE`, `FLUSH_INTERVAL_MS`) - **Cached config values** - `RedstoneListener` now caches redstone materials, enabled worlds, and removal action for better performance - **Refresh cache on reload** - Cached values are automatically refreshed when config is reloaded - **Reduced object allocation** - Avoid creating `Location` objects in hot path; only create when actually needed for logging - **Batched log writes** - Log entries are buffered and flushed every 50 entries or 500ms instead of on every write - **Improved log rotation** - Log file size is now checked on every flush, not just during cleanup task - **Primitive collections (fastutil)** - Replaced `ConcurrentHashMap<String, AtomicInteger>` with `Object2IntOpenHashMap` to eliminate boxing overhead and reduce memory allocations ### New Features - **Bypass permission** - Players with `antiredstonelag.bypass` permission can place redstone without limits - **Block owner tracking** - Tracks who placed redstone blocks for bypass permission checks - **Configurable reset interval** - New `reset-interval-ticks` config option (default: 20 ticks = 1 second) - **Debug mode** - New `debug` config option for verbose logging during troubleshooting - **Config validation** - Threshold values are now validated (must be positive) - **Alert cooldown** - 1 second cooldown between alerts to prevent spam when multiple blocks are removed - **Persistent statistics** - Statistics (`totalRemovals`, `removalsToday`) are saved to `stats.yml` and survive server restarts - **Configurable removal action** - New `removal-action` config option with three modes: - `REMOVE` - Set block to air (default) - `DISABLE` - Cancel redstone signal without removing block - `DROP` - Break block and drop item - **Warning system** - Warns players when their redstone activity approaches the threshold - Configurable warning threshold (default: 80% of limit) - Per-player cooldown to prevent spam - Only warns block owners who are online - **Update checker** - Automatically checks for new versions on SpigotMC - Notifies admins with `antiredstonelag.admin` permission on join - Non-blocking async check on startup - **Whitelist mode** - Only monitor specific chunks instead of all chunks - Configure chunks as `world:chunkX:chunkZ` format - Useful for monitoring only known problem areas ### Improvements - **Real-time statistics** - Stats command now displays actual monitored chunks, blocks, total removals, and daily removals - **Better code structure** - `CommandHandler` now receives `CounterManager` via dependency injection - **Improved config comments** - Better documentation in `config.yml` - **Stats saved on shutdown** - Statistics are automatically saved when the plugin is disabled - **Null safety** - Added null checks to `CounterManager` methods to prevent potential NPEs - **JavaDoc comments** - Added documentation to key methods ### New Permissions - `antiredstonelag.bypass` - Bypass redstone limits (default: false)
