It was only a matter of time for the very recent internal build of Windows Live Messenger to hit the public web for your own "previewing" pleasure.



Changes include:

- New user interface
- New dashboard which shows the new "In a Call" status which can be automatically enabled when starting a Windows Live Call. Also Next to the e-mail, Sharing Folders and Space icons, you'll see a new calendar/clock icon which is in fact just a link to the Windows Live Today popup.
- New icons in system tray, sign in window, and contact list
- New sounds for instant messaging and alerts
- Fixed the blocking contact icon disappearing when signing off and signing back on

There's also an A-Patch available for it.

Note: I talked with Jeff about this and I was given approval for posting this. Have fun with the latest build!
