Versioning is marketing. This is just the latest Coke Zero. Anything public facing is marketing. I remember when marketing got ahold of memory and disk size in the 1980s Then it was CPU size. Size matters. As someone once quipped, "If winning dosen't matter then why do they keep score?" Micrsoft can't release annually and Apple iOS can. That's a score. Marketing is about selling the sizzle and not the steak and versions sizzle. Forget trying to make public meaning out of them. Sales can sell bigger is better.
