Version 6 brings a much simpler registration process, particularly with more integration with Facebook and Microsoft accounts. Now you can sign in with either Facebook or Hotmail and automatically use that as a Skype log-in. The previous version briefly incorporated Facebook features; its synchronization is much more apparent in the latest release. User contacts seemed to sync with profile pictures from more sources and the overall interface also looked cleaner. It wasn't a drastic overhaul, but subtle things like removing mini-banner ads from the bottom of the contact list and thin outlines over the tabs did contribute to a more modern look.
What's new in this version:
New design: Skype comes now with a new welcome screen that gives you easier to reach sign-in options.
Video call library upgrade: Skype upgrades its video call library to improve your video calling experience. To benefit from this upgrade, make sure that both you and the person you are video calling are using the latest version of Skype.
