For starters, iOS 14.1 brings support for playback of 10-bit HDR video, along with the capability to edit such videos in the Photos app. This particular functionality is limited to iPhones 8 and above, however, so if you’re using an older iPhone, you won’t be able to play 10-bit HDR videos, or edit them directly on your iPhone. Apart from that, there are a ton of bug fixes in the mix. iOS 14.1 fixes issues with widget sizes on the home screen, and also brings a fix for an issue where adding widgets to the home screen could remove apps from their folders. The entire changelog has a laundry list of fixes that you can read below.
