If certain source code changes applied recently see through the release of the next Android version, many root apps won’t probably have the freedom like they have now and could end up broken.
One of the developers who noticed the possible changes and alerted the Android community is Chainfire, who is best known for his own slew of utility apps (SuperSU, Hotspot Control, USB Host Diagnostics, etc.) that oftentimes require root access.
As explained in his Google+ page, a healthy number of apps depend on a certain data execution method that will be no longer doable. The change in the upcoming Android version (which may be called 4.5, 4.4.3, or 5.0) is intended to be a security measure but will nonetheless be an inconvenience to app developers.
If you’re not one to heavily experiment with your device, you’ll probably be fine. But users and developers who like to squeeze every worth of their handset will be greatly affected by this change in Android. Fortunately, Chainfire and other developers already have a number of potential workarounds that can be used to update root apps. As a user, you can help by notifying your apps’ developers into making their creations compatible with the next Android version.
