It's WP 3.0.2, actually, but the dropdown lacks the latest version.
Yeah, so I installed it, added my API key, which seems valid (works with other Google Maps plugins), configured under Settings on the Plugin page.
Created a page and looked for some place to turn on map display, and nada. It is baffling because the author says, "just enter your API and play with maps". No instruction for where to look for my maps, nor how to display them.
Uninstalling it now.
