About this Mod
Modpack Update Checker is a Minecraft mod that allows players to check for updates to their modpack.
It supports both Fabric and Forge mod loaders, and is designed to be easy to configure and use.
The mod uses JSON files hosted on Github to store changelogs and version information, and can display this information in-game through a custom GUI.
The goal of this project is to provide an easy-to-use and customizable solution for modpack developers and players to stay up-to-date with the latest modpack versions and changelogs. By automating the update checking process, players can quickly and easily update their modpacks without having to manually check for updates or download files from external sources.
Modpack Update Checker currently supports the following Minecraft versions:
