Skype today caught the Mac up on versions on Thursday with the polished release of Skype 5 for Mac. The new version is the first for Apple's platform to support group video calling and handles as many as 10 simultaneous people in a slightly iChat-influenced full-screen mode. Its interface has also been overhauled and merges everything into a single pane; the overall footprint has been optimized since the beta to better have it work side-by-side on the desktop and show more contacts.
