The globally recognized standard work among the Greek New Testament editions is now available in a fundamentally revised and improved edition (28th edition). A key focus of the revision was on the textual critical apparatus, which has been structured more simply throughout. The connection of variants through "sed" or "et" has been eliminated, as well as the distinction between first and second order constant witnesses. Additionally, this edition marks the first time that the readings from the newly discovered Papyri 117-127 are recorded, which offer particularly interesting perspectives in the Book of Acts. A major focus of the revision was on the Catholic Epistles, where the edition has been adjusted to the "Editio Critica Major" with over 30 changes. The reference points in the margins have been systematically reviewed and particularly expanded.
