Annuus is a mod for minecraft networking,
\nimproves network performance and makes the game more available for running on large server.<\/p>\n
Supported minecraft 1.21.x with fabric loader and neoforge loader, needs fabric-api when using fabric.<\/p>\n
When the player doesn’t install annuus on the client, network packet will send normally like vanilla.<\/p>\n
