This was always based on 4.7.x - it never went more granular than that to 4.7.11 and so on; if it had then developers would have been needing to do updates each and every month just to reflect support for each new version (4.7.12 or 4.7.13, etc.)
End of the day - do your due diligence; check the developer's site, see if a new update has been released and check the change log if one is provided. Test, if you have the ability to do so, and if still in doubt, ask the developer.
