If you use Yahoo! Messenger on a Mac, now is the time to upgrade. The team has finally announced a new beta version with a bunch of new features. Don't get overly excited though, a major one is missing.

It's been a little while, but the time has come for the new Yahoo! Messenger Mac 3.0 Beta. We will mention this little tidbit first and slap Yahoo!'s hand a little as it is the most important feature that has not yet dropped into the application, voice calling. It's important, and Yahoo! knows this, why they released this application without it is anyone's guess. Nevertheless, the new version is out and does give users a much improved user experience.

• Tabbed IM windows now appear as separate tabs so there is less clutter on desktops. If you feel like using separate windows, drag the tab out to create one.
• Chat rooms that were once only opened up to Windows users, can now accept Mac users.
• All instant messages and all chat room conversations can be archived on your computer for searching and reference.
• Stability issues for file transfers and webcams have been fixed up and cleaned out.
• Then there are the emoticons. No user interface is complete without pretty icons, and the new Mac Messenger has them.

Yahoo! Messenger for Mac 3.0 runs on Mac OSX 10.4 or later. And please Yahoo! add some voice!
