Apple released iOS 7.1.2 and Mavericks 10.9.4 a few hours ago. Once again, at least the iOS update appears to be untried and untested. There is also an update for Apple TV, 6.2, although I did not see anything new or different in the brief look I had after the update.
Those attempting to update iOS using iTunes might be out of luck as the update might get stuck after a while. The OTA update seems to work fine on a few devices that I tried.
