According to wikipedia the last public version of Yahoo! Messenger for Unix was released in September 2003, while an unofficial beta (v1.0.6) from a Yahoo! employee was released around the same time.

But they keep upgrading the version for Mac? And now it is version 3.0.1 for the current beta released on March 26, 2010.

Yahoo Messenger has some great features that was making it so popular, and most of our customers was familiar with it, although there is an alternative like gyachi, kopete, pidgin, and empathy, our customers prefer to use Yahoo Messenger instead of those alternative instant messengers, and why?

Because Yahoo Messenger is so user friendly and easy to use, and one frequent reason is when using alternative instant messenger such as pidgin, most of our customer being afraid to create their account even without password.

The Linux / Unix version of Yahoo! Messenger is terribly outdated, and probably won’t even connect. The Windows version does not run well, even under Wine. The web version of yahoo messenger quite good but the customers still want the native version of it.
