Today, Kirk Koenigsbauer, corporate vice president in the Microsoft Office Division, announced that engineering work on the new Office and SharePoint is complete. This is great news for all developers because it truly gives you an opportunity to be on the cutting edge.
As we begin the transition to the release to manufacturing builds of our products, you may experience a bit of downtime while we upgrade your Office 365 Developer Preview sites. Once the upgrade completes, anyone signing up for an Office 365 developer site will also have access to the latest bits available. Our tools, both “Napa” – Office 365 Development Tools and Visual Studio will also be upgraded during this timeframe.
Most apps will continue to work with the RTM build but we will be constantly monitoring our forums to help you troubleshoot any issues that you may encounter.
You can read more about the RTM on Office News.
Thank you for trying out the preview and we look forward to continue seeing amazing apps from you!
