Notes about the UWP on Xbox One program and the Xbox Summer Update
As previously reported by Xbox Wire and Major Nelson, the Xbox One Summer Update has been released. If you have a console that was enrolled in the UWP on Xbox One program prior to the release of the Xbox One Summer Update, it should already be running the Summer Update console OS build (10.0.14393.1018 rs1_xbox_rel_1608.160725-1822).
If you have been thinking about enrolling a console in the UWP on Xbox One program, now is a great time to do so because with the release of the Xbox One Summer Update you no longer need to install a pre-release console OS build to do so. All you need to do is make sure that your retail Xbox One console is running the Xbox One Summer Update, then activate Xbox One Developer Mode and switch from Retail Mode to Developer Mode using the instructions at https://msdn.microsoft.com/windows/uwp/xbox-apps/devkit-activation.
Also, the Windows 10 Anniversary Update SDK has been released, and you should use this SDK and Visual Studio 2015 Update 3 when building, deploying and debugging UWPs on Xbox One. Here are links to blog posts with additional information about the Windows 10 Anniversary Update SDK:
