Generally [+] Update-Checker (You will receive a message in the server console if a newer version of MineGuard exists)
Checks [+] KillAura F (Check if the player automatically hits entities)
[+] KillAura G (Checks if the player hits entities with the inventory open)
By the way, the update checker takes some time to display the latest version. It's possible that an older version is currently being displayed. This isn't my fault, but rather a problem with the SpigotMC API.
