There will be no more updates for 1.6 based MC. The .397 that modpacks like Monster and DW20 is using is the last 1.6 version the team made before porting the mod to 1.7. So you dont need to worry about things going wrong all of a sudden due to updates.My concern is that if they disable it, and people build their systems, they're an update away from their systems exploding.
The new system adds voltage instead of treating voltage as packets. So two batboxes on a power line make it 64 EU/tick rather than two sets of 32. This makes sense but it also makes it difficult to wire a base, and one can expect transformers and batboxes to be far more needed in the next version.
So much derp...Machines explode if not provided with correct amount of energy they require to function with. Too much equivalents explosion, too little is equivalent of slow process.
