Released a few weeks ago, Apple has re-released iOS 10.1.1 for iPhone and iPad. With no release notes, the updated version of iOS 10.1.1 brings the build number up to 14B150 from 14B100.
Previously, the small build number changes were related to server updates so no OTA updates were given. The same should be expected here.
The original iOS 10.1.1 release included a fix related to the Health app. While iOS 10.1 introduced Portrait mode for the iPhone 7 Plus. iOS 10.2 is currently in beta and includes new and update emojis as well as the upcoming TV app.
