Hello cd246,


Any Rapid Security Response update comes with no new features. You can tell if it's a Rapid Security Response by the (letter) at the end of the iOS version. These updates are to fix vulnerabilities within iOS. Check out my more in depth response to what Rapid Security Response updates are here: So what exactly is this doing in the back… - Apple Community.

(a) was a Rapid Security Response to address a vulnerability within Safari, more specifically "Processing web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited."


However very few websites weren't loading after the Rapid Security Response and some users experienced issues loading. (c) was a Rapid Security Response to address this issue while still patching the vulnerability addressed in (a).
