Skype rolled out its version 5.8 software update for Windows users today, and it brings with it a couple of fairly notable 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, which will let folks share either their entire desktop or a single application with other participants on a conference call. 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.
