I'm not sure if i like the new Icon, here is why:
First: Why is the Icon a Button? I think the Icon should somehow describe the program, actually it does just add some confusion.
Second I would look for something more time-less. This Icon looks nice, because it leverages some design-trends from the last years. They are even today a bit cheesy already. (We call this hipster?) The old Icon wasn't visually that great, but surely more time-less - thus a better icon than the new one. IMHO
