Good to know

• Data is not interchangeable. The Paper and Fabric databases use different world and item identifiers. A server uses one edition.
• Fabric uses mixins for explosions, fire, leaf decay, falling blocks, villager trades and signs. If Minecraft changes such a method, that one mixin is skipped and the log shows a Mixin warning. Everything else keeps working. See Troubleshooting.
• Developers: the API has the same structure on both platforms, but uses Bukkit types on Paper and plain strings (Loc, registry IDs) on Fabric.
