Simple Modpack Update Checker Mod (26.2, 1.21.1) – Check Modpack Updates Automatically







Simple Modpack Update Checker Mod checks if your modpack has a newer version every time you launch the game. The mod will compare the current modpack version with online data and display a notification (toast) if the modpack has a new update.
