As advertised, the updates to BPOS were succesfully deployed. You'll find a new features on the administration portal such as Conference Rooms and Accept/Deny lists for Exchange Online. SharePoint Online sports a new feature we call "make me admin" that lets the logged on administrator take control of any of your SharePoint sites. This is needed in case an admin makes a site, then is unavailable when administrative action needs to occur. You'll also find that users can change passwords from home.microsoftonline.com.
With this update, we've released the "retail" version of the services. In other words, there won't be big changes between now and the time when they are available for purchase.
