I don't believe that 'AL' has changed doctrine. As for practice, it has always been variable between dioceses and countries. The concept of 'internal forum' is not new; and it is clear that, in many places, participation in the Eucharist is widespread and frequent, and that presumably not everyone taking communion is free from sin (or recently confessed).
AL gives new impetus and rationale to reach out to people who have made mistakes in life. That's most of us. 
'Familiaris Consortio'? I doubt it says what you claim. Perhaps you are misusing the word 'sacraments'. I know from other comments how you regard Pope John Paul II, and how you have scorned some of his teachings (for example, on ecumenism), and so I wonder what is so special about FC, except that you happen to like it. I've not got time to re-read it now. I'm happy to accept AL as the Church's current interpretation of these matters.
Your previous attempt at a reply to me was deleted for incivility, which tells me something.
