I am shocked there is not a fork version up already. I little interested in trying to understand what might need to change so I could get a version for the 2.1.
Unfortunately the trick of just updating the .json file doesn't work. It crashes when a belt needs to be replaced. So the mod itself would need to be properly updated. I really hope it does. It is a fantastic mod!
If this is against the rules, please let me know. But I've updated the mod and uploaded it here: https://mods.factorio.com/mod/AutoUpgrader
If Mylon updates this mod and asks that I take the updated one down, I will.
