iOS 11.4.1 beta testers, another update is coming your way.
Apple today released iOS 11.4.1 beta 3 to registered developers. If you're a dev, you can get the update over the air by going into Settings > General > Software Update on your iOS device. You can also point your computer's browser to Apple's Developer Center and get the update that way.
There haven't been any major new features discovered in iOS 11.4.1 yet, suggesting that this update is focused on fixing bugs and improving performance. That seems likely given that this is an x.x.1 update and that iOS 12 will bring new features when it launches to the public this fall.
There's no word yet on when iOS 11.4.1 might be generally released, but it's possible that we'll see another beta release or two before it is.
