iOS 11.2.6 Release Notes, Changes, Security Content: Here’s Everything You Need To Know

Apple has officially issued iOS 11.2.6 in the public domain. That release means something for a compatible iPhone, iPad, or iPod touch device owner, which can be downloaded right now. The same will also be able to grab the latest public release from the reasonable Settings app or as IPSW files to manually install via iTunes Restore mechanism.

The iOS 11.2.6 release notes by Apple gives us an insight into exactly what’s changed in this latest build.

Here’s what we are unlikely about is a lot of previous releases on Apple’s iOS roadmap, this release hasn’t been through multiple pre-release seeds for the community to test. Instead, Apple identified a critical CoralText bug issue in iOS 11.2.5, which has actually already been fixed in iOS 11.3 betas and chose to release a minor patch update to ensure that the bug was squashed without device owners having to wait for iOS 11.3 to be officially released.

Indeed, we are talking about the bizarre crashing text bug which has been causing first and third-party apps using Apple’s native text components to crash when a specific Telugu character is displayed.

As promised, Apple has quickly reacted to fix the bug and released iOS 11.2.6. It’s fairly obvious that this issue is patched with the release but the changelog give us a better insight into what Apple was thinking at the time of deciding to push out this build, as well as giving us an insight into whether or not the release contains any additional fixes, security enhancements, or even feature improvements, with the latter being unlikely this time around.


Full official changelog of iOS 11.2.6 is as follows:

iOS 11.2.6 includes bug fixes for your iPhone or iPad. This update:
-Fixes an issue where using certain character sequences could cause apps to crash.
-Fixes an issue where some third-party apps could fail to connect to external accessories.

Nevertheless, of what is in the release notes, Apple has done a great job by giving a considerable action to demand and focusing on the issue which has been causing user’s devices to crash all over the world when a specific Indian Telugu character is received.

As for security content of iOS 11.2.6, this is what Apple says:

Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation
