I'm not sure I read the change log correctly, but is the old IC2 energy system active again? I don't want to fry wires nor blow anything up to find out.
Edit: Wires didn't fry, so it looks like it isn't.
Excellent, I look forward to working around that in the future, like it was meant to be played.
Also, the mining items in IC2 no longer break blocks from other mods, like Buildcraft and Galacticraft. That must be from the change in how they are handled.
