Skype rolls out update for Windows with full HD video calling, group screen sharing

Skype is rolling out its version 5.8 update for Windows users today, and brings a couple of respected features. That includes full HD video calling (provided you have a suitable webcam and internet connection, of course), video calling to Facebook users (regardless of whether they have Skype installed or not), and group screen sharing. That last feature is only available with Skype Premium, though. Other new features include a "push to talk" option that will let you set up a hotkey to trigger your microphone (for multiplayer gaming, for instance), the ability to hide offline Facebook contacts, and one possible fruit of the Microsoft acquisition: Bing toolbar integration.
