Really surprised that Logos does not offer this already. Perhaps Faithlife has not been able to obtain the rights? Only the older, second edition is currently available. As far as I know, the third edition of the Apostolic Fathers edited by Holmes is the most current translation of the Apostolic Fathers available and has the most text-critical notes in it. While I would strongly prefer it as a Logos user, I would think Noet users would require the current version for academic use.
