To elaborate on the Skipper's (*salute!*) previous response, we set our demo store up a few weeks ago before a lot of the most recent patches were available. For those interested in seeing the demo store -
MonsterCommerce DemoWhen the development team releases a patch, the demo store does actually get updated with that patch. However, we have another process working with the demo that defeats this patch after the fact and reverts the store back to it's previous pre-patched state.
Because the demo store is open to anyone on the internet to edit it -

We had to set up something on the server that reverts the site back to a backup every twenty minutes or so. Otherwise we would have 13-year-old kids finding the site and posting f@rt jokes and other stuff we don't want up there representing our company.
You can see this in action if you go into the demo and make site changes for a few minutes. After awhile, the site automatically reverts back to square 1. This means that settings, orders, email addresses, customers, html, payment info and anything else that isn't already saved in the demo gets lost every time this site refreshes. This gives you and any potential clients a chance to see the features in action, but does not let an enterprising prankster commandeer the site for very long.
Most likely, either one of two things will happen; the developers and server admins will iron out a way for the patching scheme to write the patch to the backup as well as everywhere else OR once the manic

pace of bug fixes and patches slows down to a more normal rate (weekly or monthly instead of daily) one of the developers will just manually add the new patches to the demo.
