The datastore features page under 'Overview' is clearly version specific (3.0) from the URL. However this is not labeled anywhere on the page and is not clear. Let's add some text calling out the related version number for this page so it's clear that it applies to 3.x.
Also, this is a great page with Datastore pertinent information. As a user suggestion, it would more logically be linked under the 'Datastore' subsection rather than the 'Overview' subsection. Or at least be cross referenced there to be more easy to spot when looking for information specific to the datastore (as there is already related feature-specific information in that subsection).

The page very clearly has "DataNucleus AccessPlatform 3.0 Documentation" written in BOLD across the top. Why is that not clear enough?
Such a page would have been hidden under "datastores" in v 1.0 and v2.0 but not now, since we need to present API, Datastore, and Mapping in the overview information. Sadly the current build system for the website will not allow putting a page in multiple sections.
