Today an internal build of Windows Live Messenger 8.5 was leaked by Messenger Addictos, a site dedicated to Windows Live Messenger and related products. The new build includes a completely new installer system (though it appears it might need some tweaking). Messenger itself also got a complete overhaul, featuring a new UI that combines the best of Windows Live and Vista. The new build also includes several minor new features, some of which are still undisclosed. Unfortunately support for Plug-Ins (or 'Add-Ins') has been dropped.
