From, today onwards, Yahoo! has decided to discontinue their popular IM client, Yahoo Messenger for Vista. This doesn’t mean there won’t be any Yahoo! Messenger, Yahoo says it now focuses on keeping one client for all Windows.
Yahoo messenger for Vista was a custom IM client developed specifically for Windows Vista with graphical rich user interface. It offers the same set of features that other Windows version offers, and has no bugs as far as I know. The only feature missing is the webcam support for video calls, but that can be easily skipped.
