Apple has today released iOS 10.1. This comes after 5 betas sent to developers. This is a fairly small .x update, bringing only a few features. Most notably, we find Portrait mode for the iPhone 7 Plus. This uses both cameras to create a large depth of field. There is also now transit directions in Japan as well as many bug fixes and improvements.
To get the update, you can go to Settings > General > Software update > iOS 10.1. It’s a fairly large update so it may take some time to download and install. You can also manually download the update via iTunes by connecting your device to a computer.
