CERBON's API [Forge | Fabric | NeoForge] is a library mod holding the shared code behind CERBON's Minecraft mods. It adds no gameplay by itself, but every CERBON mod for Minecraft 1.20.1+ requires it as a dependency.
Builds exist for NeoForge, Forge and Fabric across Minecraft 1.20 - 1.21.6. The author advises updating to 1.1.0 only when a dependent mod asks for it.
