Version 4.7 is the one most of our customers are using right now. We haven't had time to validate against the 4.8 version in the current build. Also, the friendly URLs feature must be turned off, as it breaks all of the querystring data that gets passed around in the store.
When this support article becomes outdated (in regards to the version #), think of this more as a rule of thumb. Upgrading to the latest build can sometimes break compatibility of your .net application and shopping cart integration, so it's important to throughly test an upgrade in a non-production environment before applying the update live.
