Annuus is a mod for minecraft networking, improves network performance and makes the game more available for running on large server.

Supported minecraft 1.21.4 with fabric loader and neoforge loader, needs fabric-api when using fabric, needs architectury-api when using neoforge.

When the player doesn't install annuus on the client, network packet will send normally like vanilla.
