"During the Celebration of the Chrism Mass in the Cathedral of Milan, the Archbishop of Milan, Cardinal Dionigi Tettamanzi, in front of hundreds of priests, announced that in Advent of 2008 the New Ambrosian Lectionary comes into force... which was approved and confirmed by Pope Benedict XVI by the Congregation for Divine Worship and the Discipline of the Sacraments."
According to Vatican Radio, "the New Lectionary is divided into three parts (of the mystery; Mystery of Easter; Mystery of Pentecost). In addition to the Sunday Lectionary - organized over three years, A, B, and C - a special Lectionary for Saturdays was also introduced, organized into two years. This is designed to give a dignity to the celebration of the Sabbath, whose evening Mass is no longer simply the advance of the [Sunday Mass], but a way to celebrate the Day of the Lord from the previous evening, in continuity with the tradition of the Eastern Churches and Jewish [tradition]."
I shall leave commentary to people who may know more about the situation.
