Apple has today released iOS and iPadOS 14.4.1, macOS Big Sur 11.2.3 , and watchOS 7.3.2.
Though these updates appear to have been primarily released to address a specific security issue, a bug introduced in iOS 14.4, appears to have been resolved. This was the bug concerning connectivity issues for the Mantis Q 40, Chameleon 20, and both the Brailliant BI20S and bi40X models. Both the American Printing House and Humanware have posted confirmation of this resolved bug on their respective mailing lists. Though this appears to be the only fix, if you notice any changes, improvements or regressions in your own use of these releases, please post a comment with your findings.
Apple's release notes say that these updates feature “important security updates and are recommended for all users.”
The primary security fix addresses an issue with malicious content on the web involving memory corruption:
- Impact: Processing maliciously crafted web content may lead to arbitrary code execution
- Description: A memory corruption issue was addressed with improved validation.
How to update
iOS and iPadOS 14.4.1 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.
