PackPing

PackPing is a minimal update-checking utility for Minecraft modpacks. It allows a modpack to define its current version and compare it against a remote/latest version source. If a newer version is detected, the player receives a notification in-game. The mod is intended to provide a clean and lightweight update notice system for modpack maintainers
