All the new features are working fine but the config keys are buggy and for some new features you cant disable them this will be fixed in the next uodate untill then you can downgrade

Changelogs:

Added:

• Tile Entity Limiter: Limits the number of tile entities (chests, furnaces, hoppers, etc.) per chunk and globally. Prevents lag from massive storage systems. Configurable via optimizations.tile-entity-limiter.
• Spawner Limiter: Limits mobs spawned by mob spawners per chunk and globally. Prevents lag from massive spawner farms. Configurable via optimizations.spawner-limiter.
• Piston/Slime Block Limiter: Limits fast piston contraptions (flying machines, etc.) that cause server lag. Blocks piston activity in chunks with excessive piston events for a configurable duration. Players are notified when blocked. Configurable via optimizations.piston-limiter.
• Breeding Limiter: Limits the number of breedable animals per chunk and globally. Prevents massive animal farms from causing lag. Configurable via optimizations.breeding-limiter.
• Packet Rate Limiter (ProtocolLib required): Limits the number of packets a player can send per second to prevent lag and crash exploits. Players exceeding the limit are warned, temporarily blocked, and eventually kicked. Bypass permission: clearlag.packetlimit.bypass. Configurable via packet-rate-limiter. Auto-disables if ProtocolLib is not installed.

Fixed:

• Piston Limiter: Added player notification when piston activity is blocked in a chunk. Added configurable block duration (block-duration-seconds).
• Breeding Limiter: Changed from counting only breedable adults to counting all Breedable animals (includes babies). Added debug logging when debug-mode is enabled.
• Packet Rate Limiter: Uses Reflection to avoid class loading errors when ProtocolLib is not installed. Plugin now starts normally even when the feature is enabled but ProtocolLib is missing.

Removed:

• Nothing removed in this update.
