Gaedo initially stood for "Google App Engine Data Object", but has since evolved into a more general Java persistence layer, supporting:
- Google App Engine
- all graph implementations compatible with the Blueprints stack.
I used to publish a long index containing all versions of gaedo, but we've been too far.
Now, to see whcih is latest version, I urge you to go take a look at maven central, which clearly knows which is the latest version.
