Android 4.4 was only released a couple of months ago, but there are already rumors surrounding the upcoming Android 4.5. Many of the rumors aren’t based on any hard evidence, but sometimes we get something that actually has some weight.
A bit over a week ago, two commits were made to the AOSP Master Tree that prevents SU from executing files that are stored on the /data partition. The only problem with this is that a lot of the current root apps have files that are stored in directories on this partition. Because of this, if the commits are not reverted, many root-enabled apps will need to be updated in order to work with future versions of Android.
If you’re a root app developer, there are ways to get around this, as detailed in a page called How-to SU, made by XDA Senior Recognised Developer, Chainfire. The workaround use things like extracting the code and running in from RAM, or rootifs, and then running commands directly to SU.
Despite the fuss, the commits may be reverted before the next Android release, and if they are kept, there’s no telling which version of Android they will make a debut in.
