I needed to top off a vehicle I had converted to John Deere Cool-Gard (G-05) over a year ago so I stopped at a local John Deere dealer to get some. I saw they now have Cool-Gard II out.
It appears to be chemically identical to the original Cool-Gard. Here are the original Cool-Gard ingredients...
Cool-Gard II is compatible with original Cool-Gard. Both contain Bitrex to keep the pets and kids from drinking it.
Other than color and longer service life, I am not sure what else changed especially in regards to getting longer service life out of it since both are chemically identical. Regardless, I still drain the radiator and overflow tank and refill both every couple of years.
