As a result of the Vatican II council, Mazza notes that in 1969 there was a new Order of Mass published, as well as an instructional manual (Mazza 1999, 263). In it, the rubrics are accompanied by theological explanations. Within the updated Missals there are versions of the Mass for a variety of different circumstances. Mazza briefly describes the various components of the order of the Mass (Mazza 1999, 264ff).
The eucharistic prayer itself remained unchanged, still remaining consistent with the Roman Canon which was last changed in any significant way in the early seventh century (Mazza 1999, 269). Mazza observes that there had been several revisionso f anaphoras and prayers, but they were local or regional in nature. There was a move then to allow for other eucharistic prayers which could be presented along with that of the Roman Canon. The prefaces were multiplied at this time as well (Mazza 1999, 270). A variety of additional materials were published during the papacy of Paul VI.
