Customers are asking for HTML 5 support. Simply put this is a new rev of HTML. For the most part it means very little. No more frames and framesets, just iframes and web2 XHTML access. Browsers need to support certain features like video and input editing.
See http://www.w3.org/TR/html5-diff/ for the real techie stuff.
Oh and know that mymo and svg layout is supported by you customers iPhone and iPad.
For the rest of the world, the flash output support for the NOC svg rendering engine will keep all your users and browsers happy.
