- Item model support has been added. It works starting from version 1.21.4, alongside the custom model data format. You specify this in the config instead of a number if you want the item to have a custom model. The format is "your_pack:model_name". For example, "wrestling:bag".
- Common methods have been extracted and moved to a library.
