There are new versions of Skype out for Windows and Mac users. The Windows version 2.0 adds support for video calls with other Skype users, amongst changes to the interface. On the Mac, Skype 1.4 gets an updated interface with some fancy new effects and the ability to pause iTunes if you receive a call, as well as call forwarding. It doesn't have video calling yet though.
On both platforms, you'll see that the Skype icon is now light blue - previously it was red on Windows and light green on the Mac. The PocketPC and Linux versions haven't yet been updated though, and none of the versions supports talking to users of other networks like Gizmo yet.
