I don't know my version or loader
Pufferfish API
Pufferfish API is a library mod that makes it easier to develop multi-version and multi-loader mods with a single codebase. This is primarily built for my mods (excluding BTA), so stuff could break at any time, and you probably shouldn't build your own mods on top of this. This also doesn't add any content, so you should only install it if one of your mods depends on this.
