Changes of note:

"Interchange uses media queries to dynamically load responsive content that is appropriate for different users' browsers.”

http://foundation.zurb.com/docs/components/interchange.html

Offcanvas Javascript (Originally bolt-on, not bundled)

http://foundation.zurb.com/docs/components/offcanvas.html

"Abide is an HTML5 form validation library that supports the native API by using patterns and required attributes."

http://foundation.zurb.com/docs/components/abide.html

Zepto support has been removed from Foundation 5.

Docs are continuing to look better, and they still have docs back to Foundation v2.

Thanks Zurb!
