CircuitBreaker v2.4-Aegis

This release introduces the AEGIS (Async Event Gate and Isolation Sentinel) engine update, featuring surgical player alerts when chunks are frozen to keep players fully informed.

What's New:

- Chunk Frozen Chat Announcement: All players inside a frozen chunk area receive a warning message letting them know the chunk has been isolated, labeled with author attributions. - Configurable Warning Message: Define a custom warning message using chunk-frozen-message in config.yml. - All Rights Reserved License: Transitioned under a custom All Rights Reserved Software License Agreement.

Advanced Sentinel Panel & Webhook Release v2.3 - In-Game GUI Control Panel (`/cb gui`): A custom interactive chest GUI dashboard allowing admins to view server health, list/teleport/unfreeze frozen chunks, and manage whitelists. - Discord Webhook Alerts: Sends rich, customizable embed alerts to your Discord channels when lag machines are neutralized. - Server TPS Sentinel: Asynchronously monitors TPS/MSPT and broadcasts warning reports to admins and Discord when sustained server resource drops occur. - Automatic Updater: Asynchronously downloads official plugin releases into the server's update folder for seamless, crash-free restarts. - Countdown Unfreeze Timers: Displays the remaining freeze duration of active frozen chunks dynamically inside the GUI panel.

Advanced Sentinel Release v2.2.1 - Physics Events Defused Counter: Added tracking and persistent saving of total physics events blocked in frozen chunks. - bStats Custom Charts: Added a live line chart tracking physics_events_defused to show real-time performance impacts on the bStats dashboard.

Advanced Sentinel Release v2.2 - Dynamic Threshold Scaling: Automatically adjusts physics event thresholds based on live TPS and MSPT load averages. - 3x3 Chunk Freezing: When a chunk triggers Strike 3 (Hard Freeze), a 3x3 grid centered around that chunk is frozen to catch machines spanning chunk borders. - Clickable Chat Alerts: Broadcasts interactive admin alerts with built-in [TP], [UNFREEZE], and [IGNORE] actions. - Improved `/cb unfreeze` command: Supports optional radius (e.g. /cb unfreeze 3) and falls back to a 10x10 block area unfreeze if omitted. - `/cb top` subcommand: Real-time diagnostics command showing top 5 chunks with highest block physics activity. - Packet Spam Sentinel: Dynamically injects into player Netty connection pipeline to throttle packet-spam crash exploit clients.

Optimization & Update Checker Release v2.1.1 - Optimized Physics Checks: Replaced expensive Bukkit event.getBlock().getChunk() calls inside LagListener with fast bit-shifted coordinates (block.getX() >> 4). - Memory Leak Prevention: Decoupled chunk tracking maps from strong org.bukkit.Chunk references using a custom ChunkKey class, allowing unloaded chunks to be GC'd. - Load-Spreading Scanner: The entity culler now spreads its chunk scanning workload across ticks (processing batches of 50 per tick) to eliminate main-thread TPS micro-stuttering. - Update Checker: Integrated an asynchronous update checker checking GitHub releases.

v2.0: The Performance Suite Update

This is a major feature update that introduces the Entity Culling System, transforming CircuitBreaker from a specialized physics-lag tool into an all-in-one server performance suite. ---

New Feature: Entity Culling System

A new, optional system has been added to detect and clear excessive entity build-ups. This runs completely separately from the v1.0 physics lag detector. Fully Configurable: The entire feature is disabled by default*. You can enable it and configure it in the new entity-culling section of your config.yml. New Scanner:* A new, slower, and server-friendly scanner (startEntityScanner) runs on its own configurable timer (scan-interval-seconds) to check for entity-crammed chunks. Threshold Culling:* If the number of entities in a single chunk exceeds the entity-threshold, the plugin will perform a "cull". Admin Notifications:* When a cull occurs, a message is sent to the console and to all in-game admins (with the antilag.notify permission) detailing how many entities were removed and from which chunk. ---

Smart Culling: No More Deleting Pets!

The biggest feature of the new system is its "smart" culling logic. The plugin will NOT remove entities that are considered "important." An entity is considered important (and will be skipped) if it: * Is on the new entity-culling.whitelist in the config (e.g., "PLAYER", "VILLAGER"). Has a custom name*. Is a tamed pet*. Is a vehicle*. ---

Quality of Life & Fixes

Console Color Fix:* All console messages (startup, shutdown, and warnings) have been updated to use Bukkit.getConsoleSender().sendMessage() for proper, sexy "blood-red" color rendering that avoids §c artifacts. Code Cleanup:* Cleaned up various classes and fixed minor bugs from v1.1.
