Those of you using Skype in Windows 8 will be happy to know that Microsoft's just bumped the app to version 1.6. It's been a few months since the last update, and this revision brings more features to the table, including contact blocking and a slew of performance tweaks. You're now able to block users, with an option to remove or report the offending party. Speed and reliability have been improved, especially when loading contacts, and a number of bugs have been fixed, including one where the outgoing video was not always displayed after switching cameras. The update's available in Windows Store, so what are you waiting for?
