iOS 7.1 has finally been seeded to developers. It has a build number of 11D5099e and seems to be just bug fixes. As soon as we find out about more about the change log we will post it for you guys.
In the mean time if you are a developer head over to the iOS Dev Portal and update your devices. If you plan on jailbreaking in the future, you should stay away from any updated especially beta updates.
