Yahoo Messenger 7.0 is out of beta, not calling itself version 7.0 any more but Yahoo Messenger With Voice.
Yahoo upgraded some new features such as constant-connection voice calling, drag-and-drop file sharing, drag-and-drop photo sharing, and a beta feature called LiveWords that searches highlighted text from the IM window.
This must be Yahoo’s answer to Skype and perhaps, an opportunity for AV Voice Changer Software to show its power!
