Microsoft’s Steve Ballmer has lifted the lid over the latest version of Windows Live Messenger, dubbed “Wave 4″.

Comparable to Facebook Connect, it allows Messenger to integrate with websites so that you can chat about and share all of them with your pals.

What’s more, it allows users to send messages from the client directly to Facebook.

They’re two big features Messenger has been missing for some time now, with tabbed windows especially coming as great relief to those who’s chatty friends mean they often have many flashing Messenger conversations going at the same time.

Expect a beta version with the software to touch down during the summer time.
