Optional registries / stricter defaults
The goal of these changes is to document the expected behaviour of missing registry's when a client connects to a modded server. This behaviour is now consistent between a vanilla clients and modded clients. This has nothing to do with individual registry entries (yet).
Some mods have their own registries that only need to be synced when the connecting client has their mod, I have added a new
OPTIONALregistry attribute that allows this. This attribute is sent in the registry sync packet.The behaviour of a connecting client is as follows:
These changes will only apply to 1.21.4 as they are breaking.
