# Phew! New Demonstrations site up...

/A little tougher than I thought it was going to be to get everything lined up for release.

Our "knowledge app" site demonstrations.wolfram.com was completely redesigned to use the inline Mathematica 8 or free Wolfram Player plug-in rather than having to open a separate window (alongside various other changes).

This apparently small plug-in change makes a big usability difference and by the same token, it changed the site workflow quite a bit. It also required the latest version of Player--just releasing too--and itself quite a feat of engineering.

One of the complexities has been to work through all the cases of different machines, installations and therefore optimal operation. What should the site show if someone has Mathematica 7 (no plug-in capability) installed? Or they're on an iPad (no Player for now on iOS)? Or it's a complex demonstration that takes some time to compute? Each has its own adjusted workflow.

Hopefully, we've ironed out these cases but with the traffic we get, I'm sure we'll find out anywhere we haven't soon. Getting this optimised is a high priority: Demonstrations is one example of much broader interactive publishing plans codenamed CDF.
