But that's mentioned by dear Caravellarella,

Air France decided to purchase D.338s as transition aircraft due to the delay of the T30 program aircraft. However, they are not part of the same program at all; they were not presented as competitors to CEPANA, which chose the Bloch 300 and the D.620.

You can refer to Avions issues 179 and 180 (January to April 2011) for D.620 that became D.342, as well as issues 201 and 202 (September to December 2014) for MB.300, and of course, the 2nd volume of "Les avions Marcel Bloch" (2025).
