Actually, let me qualify that:
When installing, I provided the license key, and when I go to BE icon button thing --> Installation and Licensing --> License Information, it shows up with "yes" for both licensed and installed. If that's what you mean by enabling it, then yes.
Looking back manually to Dec 2011, there's nothing about this issue.
As an aside - wouldn't the site's search function find it if it was in there? Or is the Known Issues section not covered by it?
