Added

Housekeeping

This update brings experimental Spigot 1.17 support.

Mimic support
Mimic automatically detects classes and levels plugins that you use and RPGInventory will use it for items and slots requirements.
All supported level and class systems are available on this page.
With Mimic you can add support of your own levels/classes plugin.

Removed level-system and class-system options from config.
Option slots.level.spend works for any level system.

Added RPGInventoryItemsRegistry.
You can get RPGInv items using command:
Added

• Validation of slot IDs on slots initialization
• Validation of allowed and denied items on slots initialization

Fixed

• Dupe when pressing F on item (#168)
• Fixed errors after plugin reloads
• Fixed dependencies relocation
• Removed SLF4J from dependencies

Custom Model Data
Now you can switch textures type between Custom Model Data and damage. Just change option textures-type in the config. There are two possible values:

• damage (default value) - https://www.spigotmc.org/wiki/custom-item-models-in-1-9-and-up/
• custom_model_data - modern replacement for textures by damage available since 1.14

We also created resource-pack majesty using Custom Model Data. It is fully compatible with the default plugin config. https://gitlab.com/endlesscodegroup/rpginventory/resource-packs

Other changes
This release contains a lot of small but significant fixes and improvements. We improved default configs. Now it should be less confusing for new plugin users. Version 1.15 now is fully supported. Also, there is initial support of 1.16. By the way, NETHERITE tools and armors are already in default configs
