ClearLag 2.0

A major expansion of ClearLag, adding full mob cleanup, spawn control, live JSON configuration, and new admin tools.

Added

• Added scheduled mob cleanup alongside dropped-item cleanup.
• Added configurable cleanup rules for hostile, passive, ambient, water, and specific modded mobs.
• Added preservation options for named, tamed, persistent, and boss mobs.
• Added configurable chat warnings before mob cleanup.
• Added configurable cleanup completion messages showing how many mobs were removed.
• Added /clearlag entities clear for manual mob cleanup.
• Added mob spawn prevention controls.
• Added support for blocking both vanilla and registered modded mobs from spawning.
• Spawn prevention takes effect immediately after config reload without removing mobs that already exist.
• Added live JSON configuration under config/clearlag/.
• Added automatic config reloading when JSON files are changed while the server is running.
• Added /clearlag reload for manually reloading ClearLag configuration.
• Added the ClearLag Spawn Control Tool.
• Server admins can right-click a mob with the tool to immediately enable or disable future spawning for that mob type.
• Added /clearlag spawning tool for obtaining the Spawn Control Tool.
• Added a configurable option to completely disable the Spawn Control Tool.
• When the tool is disabled, ClearLag can remain server-side only without requiring clients to install the mod.

Configuration

• ClearLag now uses JSON configuration files for cleanup and spawn-control settings.
• Existing ClearLag configuration is migrated automatically when upgrading.
• Existing settings are preserved during migration.
• Original configuration files are backed up before migration.
• Added configuration schema versioning for safer future upgrades.
• Invalid JSON will no longer replace the last valid runtime configuration.
• Unknown or invalid entity entries are reported without breaking the rest of the configuration.

Spawn Control

• Administrators can blacklist individual mob types from spawning.
• Supports vanilla and modded registered entities.
• Spawn rules update live without restarting the server.
• Existing mobs are not automatically removed when their type is blocked from future spawning.
• Mob cleanup and spawn prevention remain independently configurable.

Server Administration

• Added new /clearlag commands for entity cleanup, configuration reloads, and spawn-control management.
• Mob cleanup and spawn-control actions report useful results back to administrators.
• Cleanup warnings and messages can be customized directly from JSON.
