A further development of the Didaché, “adapted to the state of the Eastern Church in the first half of the fourth century,” is contained in the Seventh Book of the Apostolical Constitutions of Pseudo-Clement of Rome, chs. i.–xxxii.  “Here the Didaché is embodied almost word for word, but with significant omissions, alterations, and additions, which betray a later age.…The Didaché was thus superseded by a more complete and timely Church Manual, and disappeared.”  Dr. Schaff has appended this document also to his edition of the Didaché, noting the borrowed passages on the margin, and distinguishing them by spaced type in the Greek text, and by italics in the English translation.
