Google Keyboard vs Android Keyboard (AOSP) Is there a difference between Google Keyboard, which was recently release on the Play Store, and the Android Keyboard (AOSP) in the open source project?

Update: I need the difference from a feature prospective
It's exactly the same keyboard as the Android Keyboard from Jelly Bean (4.2) as I read.
See i.e. this article.

Rereading exactly points out that this app should expose the keyboard which was only installed on Nexus phones with Android 4.2 to prior android version (4.0+) on other smartphones and tablets including features like "swiping" and gestures.
