I'd like to start a side project that will rely heavily on the relationship between places, and GeoPlanet does this wonderfully. However, the latest version I can find of the data GeoPlanet Data v7.10.0, is from 2012-06-01. The Yahoo GeoPlanet Docs are still available, and the Yahoo GeoPlanet Data Download Page still says that they're working on a better way to surface the data, but there's no sign of an update, and various sources found via Google News Search state that Yahoo would kill the service last year.
This is confusing and discouraging. It doesn't feel safe to use their API or the data at the moment, given it's likely end-of-life and the API data is, without evidence to the contrary, no longer being updated. Is there any evidence otherwise?
