A little late to report (I was watching the World Cup 
) but finally the day has come when Windows Live Messenger is final. Sporting mainly bug fixes over the last beta release, it’s available for download from messenger.live.com. For languages other than English, head over to Mess with MSN Messenger for many links.
The full version number is 8.0.0787. Check out the official press release and a Q&A session with Martin Taylor, Microsoft Corporate Vice President of Windows Live and MSN.
