    sorry did not notice below in the KB article at first, I guess that answers my question.
    “Note We recommend that you test hotfixes before you deploy them in a production environment. Because the builds are cumulative, each new hotfix release contains all the hotfixes and all the security fixes that were included with the previous update package. We recommend that you consider applying the most recent fix release that contains the most necessary hotfixes. ”
