I'm sorry to say that the app has not improved.
The About section of the app says it's v8.1 (although the software applet of the OS says it v2.0..he)
No new functionalities whatsoever.
As a matter of fact, I'm having some GPS tracking issues with the Pre2.
This is the only issue I have with the device so far, and I cannot tell yet if it's software or hardware.
It seems like the initial localization works well but when I'm on the move, the position updates like once every 5/6 seconds. On my Pre+ in was once every less than 1 second.
Also, and this is why I suspect there might be a software component to the issue, one of my other navigation apps that worked with WebOS v1.4.5 simply does not with WebOS2.0. I get a "unable to get GPS data" error message.
I certainly hope the poor refresh time is a temporary bug, and not a "power consumption fix"!!
Wait and see...
