Apple has today released iOS 14.7.1 and iPadOS 14.7.1, bringing a fix for a bug introduced in last week's iOS 14.7 update that prevented the Apple Watch from being automatically unlocked when connected to Touch ID iPhones.
As the release notes only mention this one specific fix, our expectation is that they do not contain any accessibility changes for blind and low vision users; however, if you notice any changes, improvements or regressions in your own use of these releases, please post a comment with your findings.
iOS and iPadOS 14.7.1 are available via Over-the-Air Update (Settings > General > Software Update) via Finder on a Mac with macOS Catalina or later, or via iTunes on a PC or Mac with macOS Mojave or earlier.
Before updating, we strongly recommend making a full and complete backup of your device (either locally or in iCloud, depending on personal preference). This will ensure that, in the unlikely event that something goes wrong during the update process, you will have a current backup on hand in case a device restore becomes necessary. Also, if using OTA update, we recommend plugging your device into a power source for the duration of the download/installation process, so as to prevent the unlikely event of your battery going dead during the update.
More information on how to update the software on your device is available on this Apple Support page.
