＞Because we want to provide our users with the best possible Skype experience, necessary changes must be made along the way. So, beginning March 1, users running older versions of Skype for Windows desktop (7.16 and below) or Skype for Mac (7.0 to 7.18) will no longer be able to sign in. If you’re one of those users, all you’ll need to do is download the new update.
