Controlling the Release of Updates for Your Apps
Version Release Control is a recently added feature in iTunes Connect that is presented when you submit updates for your apps currently on the App Store. This feature gives you the option to either automatically release an update once it’s approved by the App Review Team, or release it yourself through the Manage Your Applications module. If you select to release a version yourself, it will appear as Pending Developer Release once it has been approved and will remain in this state until you release it to the App Store. You will receive an email reminder to release a version of your app if it is in the Pending Developer Release state for longer than 30 days. For more details, read the Version Release Control section of the iTunes Connect Developer Guide .
