WARNING: IF YOU'VE MADE ANY CHANGES TO THE ITEMS IN THE CONFIG, THEY WILL BE DISCARDED. BACKUP THE CONFIG.YML FILE BEFORE UPDATING!
This update brings a plethora of new options to the items section of the config. Attributes are now in the config, so you can add new ones or change existing ones. This allows you to change attack speed, attack damage, or even add stuff like movement speed. There's now also an option to change the color of Leather Armor.
There have also been a few bug fixes related to the config and some compatibility improvement for lower Minecraft versions.
