What are the differences between display:box and display:flexbox

Question

It's my understanding that the CSS Flexible Box Layout module is being rewritten and that display:box is being deprecated in favor of display:flexbox.

Is display:flexbox currently supported in any browser (release, beta, or nightly)? Does anyone know where I can find some information as to what's new in flexbox, what the differences are between it and the old module, and/or why the old module was rewritten?

Answer 1

It looks like at this time good information is not available. I will update this post if and when I find good information.

Update: (2/20/2012) caniuse.com now shows the browser support for both the new and old versions of the Flexible Box Layout Module

Update: (8/7/2012) Chris Coyer has put together a nice article about how to tell the difference between the new and old syntax. http://css-tricks.com/old-flexbox-and-new-flexbox/
