The Google Maps Mobile page is so void of details that I can't tell what version number they've released or even when they release them. The client really should alert you when there's a new version.
I've just happened to stumble upon the latest (1.3.1) version, because I saw mention of the traffic feature which I did not have. I wasn't positive of what version I was getting until I actually downloaded it to the phone. I found a quick message buried in a Google Group about a new release, but nowhere official, like the homepage for the thing.
It really is my current killer app on my phone, and they keep making it better, but they need to market it a bit more effectively.
