Security Improvement Update for macOS Tahoe 26.3.1 & iOS 26.3.1 Released

Apple has released what they are calling a “Security Improvement” as a software update for macOS Tahoe 26.3.1, iOS 26.3.1, and iPadOS 26.3.1. The update, err, improvement, is being labeled as macOS Tahoe 26.3.1 (a), macOS 26.3.2 (a), iOS 26.3.1 (a), and iPadOS 26.3.1 (a), and though it installs just like a software update, you won’t find it available as one.
Curiously, the “Security Improvement” is not available through the standard Software Update mechanism on your Mac, iPhone, or iPad, so if you go looking there you will not find any updates available. Instead, the ‘improvement’ is buried inside of a completely different section of settings where almost no user is going to look or even accidentally stumble into it. It would make a lot more sense to my plebeian logic to place all system updates inside of the regular “Software Update” section of Settings, but here we are.
