Here are the top 5 new features of android 4.3 and how it is different from android 4.2.2 android 4.3 features.

1.  Restricted profiles support

With restricted profiles, you can keep your kids or anyone else out of apps or websites you don’t want them to see.  According to Google, “Each restricted profile offers an isolated and secure space with its own local storage, home screens, widgets, and settings. Unlike with users, profiles are created from the tablet owner’s environment, based on the owner’s installed apps and system accounts. The owner controls which installed apps are enabled in the new profile, and access to the owner’s accounts is disabled by default.”  

2) OpenGL ES 3.0 for High-Performance Graphics:

Android 4.3.3 users will enjoy high graphics games, but the right hardware will be required to backup OpenGL ES 3.0 capabilities.  Today, this is only supported on the new Nexus 7, Nexus 4, and Nexus 10 devices. More will also follow.  Developers will most likely start taking advantage of OpenGL ES 3.0( Let’s hope emulators like PPSSPP PSP emulator will also update and take advantage of OpenGL ES 3.0 to improve things).

3) Notifications

Until Android 4.3 appeared, developers couldn’t access the status bar area.  Now they can, that is, if you, the user allow them to. What developers can do is register a notification listener service that, with your permission, will receive all the data notifications when they’re displayed in the status bar.  The devs can now make a new class smart apps to take advantage of this feature.  

4) Bluetooth Smart Read technology support

Android 4.3 will take advantage of the new Bluetooth smart ready technology Bluetooth Smart Ready devices are the most effective means of connecting to the billions of Bluetooth devices already in users’ hands — and to the more than 5 million Bluetooth enabled devices commercialized each new day. Examples include phones, tablets, PCs, TVs, even set-top boxes and game consoles that sit at the center of the consumers’ connected world. These devices efficiently receive data sent from Classic Bluetooth devices and Bluetooth Smart devices and feed it into applications that turn data into useful information. They are the hub of the Bluetooth system.  

5) Better DRM management

We hate DRM, but it’s here to stay. The net effect of these changes is it will make DRM easier to manage and it should make video streams with DRM, which are pretty much all of them these days, look and play better. Like I said, Google is making the best of an annoying commercial video necessity.   In conclusion, you can bet that Cyanogenmod or other Developers will be porting 4.3 to as many devices as soon as possible, before they get an official release for your device from your carrier or manufacturer.
