Developer’s note: Advancements optimization mod, updated fork of Icterine with added features

Cerulean, smoother advancement checks

Cerulean is a Java Edition optimization mod that improves Minecraft’s advancement checking system, with special attention to the resource intensive InventoryChangeTrigger. This trigger can create noticeable lag when a modpack includes many custom advancements, datapacks, or item based objectives.

As an updated fork of Icterine, Cerulean supports Fabric, Forge, and NeoForge on selected versions such as 1.20.1 and 1.21.1. It can process checks every few ticks while ensuring a player’s first item pickup is recognized immediately. Configurable injections let server owners adjust or disable its behavior, helping our Minecraft server deliver a more stable modded experience with BoxToPlay.
