Yes. That version of the US GIRM (1975), fourth edition, has an appendix listing changes. No. 240 reads:
"240. DISTRIBUTION OF COMMUNION
On June 17, 1977, the Congregation of Sacraments and Divine Worship
approved the request of the National Conference of Catholic Bishops
to permit the optional practice of Communion in the hand. The
Bishops’ Committee on the Liturgy, in its catechesis about this
optional practice, drew attention to these considerations:
a. Proper catechesis must be provided to assure the proper and
reverent reception of Communion without any suggestion of wavering on
the part of the Church in its faith in the Eucharistic presence.
b. The practice must remain the option of the communicant. The priest
or minister of Communion does not make the decision as to the manner
of reception of Communion. It is the communicant’s personal choice.
c. When Communion is distributed under both kinds by intinction, the
host is not placed in the hands of the communicants, nor may the
communicants receive the host and dip it into the chalice. Intinction
should not be introduced as a means of circumventing the practice of
Communion in the hand.
d. Children have the option to receive Communion in the hand or on
the tongue. No limitations because of age have been established.
Careful preparation for first reception of the Eucharist will provide
the necessary instruction. (See also the Roman Ritual, , no. 21.)"
