Obsidian (API) is a multi-loader wrapper, as well as a set of utilities that I use for my mods.
This mod is subject to sweeping internal changes including refactoring as I see fit, and as such I advise against depending on it in it's current state, however it is safe for use in modpacks.
This mod is only released for 1.21.1, and will only be maintained for the latest version released.
