NoCheatPlus attempts to prevent cheat clients from exploiting weaknesses
of Minecraft or its protocol, making your server more safe. Checks
cover a wide range of issues including flying and speeding, fighting
hacks, fast block breaking and nukers, inventory hacks, chat spam and
other types of malicious behaviour.

New Updates:

• • Basic adaption to 1.12.2
    

• • New block compatibility flags (aiming at protocol support, e.g. with soil).
