It's their Super Light with different geometry.
Women are generally shorter in torso and longer of legs than men.
Consequently, you can end up stretched out too much due to a top tube that's too long. These new bikes address that issue really well. It feels a little odd at first if you're accustomed to having been stretched out over a long top tube in the past, but I very quickly adapted to the more upright position and not only didn't feel like I was sacrificing anything, but gaining in comfort, confidence, and maneuverability. But, the final word is fit and you have to look at what fits you, the individual, best that you'll enjoy riding and that performs for you. There are tons of choices to pick from.
