First developer preview build was released back in March which was a surprised move from the Company. The company also demoed some features & upcoming features about the Android at the annual developer conference I/O 2016.
Now there is a new leak that gives us details about some design changes in the Android N. The new design changes will come in the Navigation buttons of Android N. It has been reported that the Home & back buttons of Android N will see some design changes in the upcoming or final build . The long press Google Now on Tap is also visible from the navigation button in the Home button. The design is not available in the current preview builds of Android N. So we can expect this design to come in upcoming builds.
We can not fully rely on this rumor as this could be just rumor.
