If u want to update your mod and recieve compatibility with K2 then you should add in your code in file "equipment-vehicle.lua" numeral "2" for "Krastorio2" instead of "Krastorio" in string "if mods["Krastorio"] then".
Else all K2 equipment for vehicle`s wiil not work with your vehicles.

No
I would've to change that for every one of my mods then. If people use the old Krastorio then they're lucky to have that support.
For Krastorio2 please use the compatibility mod i specifically made for this: https://mods.factorio.com/mod/kj_kras_compat
