Well, the guidelines of the Bishops from Malta were published in L’Observatore Romano - the Vatican Newspaper. I guess this makes it the official interpretation of the Vatican.

Theologian to La Civiltà Cattolica: “Yes” to exceptions for divorce and remarriage
“Francis’s vision is that of a Church for all, because Christ really did die for all men, without exception, not just for some.” The “law of gradualness” does not mean “gradualness of the law” or relativism. It is possible to consider exceptions on a case-by-case basis, admitting remarried divorcees to the sacraments, without changes to the doctrine. This is according to Dominical theologian Jean-Miguel Garrigues, Professor of Patristics and Dogmatics at the Institut Supérieur Thomas d’Aquin, at the Dominican House of Studies in Toulouse and at the Seminaire International St Cure’d Ars. He and his confrère, Cardinal Cristoph Schönborn, the current Archbishop of Vienna, composed the Catechism of the Catholic Church prepared under the supervision of the then Cardinal Joseph Ratzinger. Fr. Garrigues discussed the issues of the Synod with Fr. Antonio Spadaro, Editor-in-Chief of La Civiltà Cattolica and the transcription of their conversation appears in the latest issue of the periodical. Although he does not refer to him directly, at one point the Dominican theologian pulls apart the theory put forward by US Jesuit Joseph Fessio, who wrote that contraception can be more serious that abortion.

“Communion for remarried divorcees does not affect doctrine but discipline”
“The Sacred Tradition, as the Word says, is the oral and faithful transmission of the divine revelation and the apostolic preaching of the Word of God throughout history, is a living Magisterium, assisted by the Holy Spirit. Christ entrusted the apostles and their successors with the transmission of the faith, under Peter’s guidance, from generation to generation, right up until today, right up until Francis’ pontificate and until the end of the world…"
