One of the new features in iOS 16 is Rapid Security Response,
which lets Apple push out important security fixes to users
without requiring a full iOS update. For users running the iOS
16.2 beta, Apple today released one of those updates to deliver
unspecified bug fixes affecting the software.
iOS Security Response 16.2 (a) arrives via the standard Software
Update mechanism in the Settings app, but is a relatively quick
update, requiring just a couple of minutes to download and prepare
the update and then a quick restart and install process.
