EDIT: Two of these volumes are forthcoming (Methodological Foundations and Martyrdom of Peter/Paul), but you can pre-order them.
Three new titles are available for purchase or pre-order from SBL Press, and they all look tantalizing.
The Didache: A Missing Piece of the Puzzle in Early Christianity (Early Christianity and Its Literature), ed. Draper and Jefford
- This is an edited volume with essays discussing liturgical and ritual constructions in the Didache, background studies, and the document’s relation to the Gospel of Matthew.
The Ancient Martyrdom Accounts of Peter and Paul (Writings from the Greco-Roman World), by David Eastman
- This book for the first time collects the various ancient accounts of the martydoms of Peter and Paul, which number more than a dozen, along with more than forty references to the martyrdoms from early Christian literature. At last a more complete picture of the traditions about the deaths of Peter and Paul is able to emerge.
The First Urban Churches 1: Methodological Foundations (Writings from the Greco-Roman World Supplement)
- This collection of essays examines the urban context of early Christian churches in the first-century Roman world. A city-by-city investigation of the early churches in the New Testament clarifies the challenges, threats, and opportunities that urban living provided for early Christians. Readers will come away with a better understanding of how scholars assemble an accurate picture of the cities in which the first Christians flourished.
