We're aiming for early next week but it may be as late as Friday, December 15. We are polishing, testing, writing stories about the new features, putting up web pages, and sending emails right now. Studio Manager 10 is a major new release and we are blogging about it at Studio Manager Story. There are two posts on Studio Manager 10 over there right now. More to come asap.
Part of the Studio Manager Story is that Studio Manager 10 takes advantage of new features in FileMaker Pro 10. Those new features and how we've taken advantage of them is the subject of some of our next blog posts on Studio Manager Story.
