What is Facebook application actual width

Question

I am an facebook developer and today all my 760px wide facebook applications changed. It looks liek width is 1100 px approximately, but I cannot figure out any official facebook explanation for that ? Does anyone knows anything about this ?

Thanks

Almost as wide as the browser window, if you build your app with Fluid Canvas. Which you should. https://developers.facebook.com/blog/post/549.

The traditional size is 760 px. http://developers.facebook.com/docs/reference/javascript/FB.Canvas.setSize/
