The universal norm in the GIRM for the last 37 years has been kneeling only at the Consecration. As far as I can tell from the Latin text I’ve seen, nothing has changed in that regard.
That said, different Bishops’ Conferences asked for and received adaptations for their own countries. The US asked for kneeling during the entire Eucharistic Prayer and the Vatican said OK so that binds the entire country. The US also asked for and received the adaptation that everyone will kneel after the Agnus Dei unless their bishop has decided otherwise. If the bishop of the diocese decrees no kneeling at that time the faithful in a spirit of obedience are supposed to obey. Here is the relevant article from the US GIRM:
GIRM 43 (…) In the Dioceses of the United States of America, they should kneel beginning after the singing or recitation of the Sanctus (Holy, Holy, Holy) until after the Amen of the Eucharistic Prayer, except when prevented on occasion by ill health, or for reasons of lack of space, of the large number of people present, or for another reasonable cause. However, those who do not kneel ought to make a profound bow when the Priest genuflects after the Consecration. The faithful kneel after the Agnus Dei (Lamb of God) unless the Diocesan Bishop determines otherwise.
Now, after Communion the universal GIRM only says that you may sit during the sacred silence after Communion. That has been interpreted by many as sitting only after everyone has received Communion and the period of silent reflection started (a period of silence that lasts about 30 seconds in many parishes) and they tried to impose standing on everyone until that time. In fact, Rome was asked the question “Does the fact that the universal GIRM says that we stand until the period of silence mean that those who were used to kneeling when they return from Communion may no longer do so?” Rome replied that while unity of posture was important, this particular item was not to be interpreted so rigidly as to forbid kneeling, or in fact, sitting, upon return from Communion if that’s what the person wanted. OTOH, it didn’t rewrite the wording of the GIRM that I’ve been able to see. The universal norm remains we stand after Communion. The US GIRM says this:
GIRM 43 (…) The faithful should sit, on the other hand, during the readings before the Gospel and the Responsorial Psalm and for the Homily and during the Preparation of the Gifts at the Offertory; and, if appropriate, they may sit or kneel during the period of sacred silence after Communion.
Canada follows the universal norm but added, in our GIRM, that in those parishes where kneeling for the entire Eucharistic Prayer and after the Agnus Dei had been the custom it was good to retain that.
