As expected, Apple has today released revised builds of iOS 18.7.7 and iPadOS 18.7.7, bringing a fix for the critical, actively exploited security vulnerability known as "DarkSword." Originally released alongside iOS 26.4 and iPadOS 26.4 for devices unable to run iOS 26 or iPadOS 26, today's revision expands availability to users who have consciously chosen not to install the version 26 upgrade.

As iOS 18.7.7 and iPadOS 18.7.7 were not distributed to external testers prior to their release, we do not have any information on whether they contain any accessibility fixes for blind, deaf blind, or low vision users at the time of writing. However, as these updates appear to have been released to address a specific issue in a prior major version of the operating systems, we do not expect them to contain any such fixes.

Just a question here. The subject line says iOS 18.7.7. However the release notes say iOS 18.7.8.
Am I missing something here?
