Because Android is open source, the Android Open Source Project (AOSP lets anyone explore the source for Google’s mobile platform, modify it, and build it to suit their needs. That means you can check out what’s new in Android 4.4.1 if you know where to look.
Looking through hundreds of new AOSP code commits can be cumbersome, but the guys at Funky Android have sorted and aggregated all of the additions as well as their descriptions, and categorized them by project. Their latest changelog shows you every commit made between Android 4.4 (build KRT16M) and Android 4.4.1 (build KOT49E). If you like diving into the technical details of software development, this one is for you.
