!!! Breaking Feature:
Disabled by default item decoding, what does it mean?

  • This speed up netty threads a lot so you may incredibly have less CPU usage of your minecraft server compared to a server without LPX (lol)
  • It was not heavily tested by many customers and this feature MAY cause strange issues so it must be considered as a BETA thing, in case you found problems please report it
- Added ItemI check that should patch a Xynis crasher
