Here is a Skype pre-release version of Windows 8.1.

With this new version, you will be able to view your missed calls and instant messages. You can answer calls directly from your lock screen; you’ll be able to choose how you want to respond, whether answer a call with video, audio or decline and send an IM instead. Among the new features, with Skype for Windows 8.1, you can click to call directly through your browser.

Connectikpeople has also observed that, in Windows 8.1, Skype will automatically move to the side when you

select any link in Skype or shared item. You can also snap Skype and adjust the size of the window, so whether you’re watching a show, listening to music, playing a game together or co-editing a document.
