A major catechism has to be approved by the sui iuris Church’s Holy Synod and it’s head. Minor catechisms, while useful, are not “official” to the same level. It isn’t that difficult.
The 1850s Keenan Catechism, with imprimatur, denied dogma proclaimed in our day:

Q: Must not Catholics believe the pope in himself to be infallible?
A: This is a Protestant invention; it is no article of the Catholic faith; no decision of his can oblige, under pain of heresy, unless it be received and enforced by the teaching body; that is, by the bishops of the Church.
It was later edited after the dogma was proclaimed in 1870.
Both are ‘official’ for it’s day. Were Latins in 1869 and 1870 a different species of Latin?
