You will have to consult Fr. Hans Kueng to find out when the official Magisterium changed its teachings and on what matters. I know of none. LET'S consider usury, a matter Kueng considers. The Church forbid its practice for several centuries on the grounds that inanimate things can't reproduce themselves.
Money is inanimate, thus sterile.
I doubt whether reigning pontiffs of the period ever issued any statements of any weight tantamount to an encyclical of today or even of a dogmatic declaration. However, they did teach no usury. For a Catholic of those days to accept usury would be a sin, a sin of disobedience, even though today's Catholic can accept usury, or interest on capital. For centuries, Catholics couldn't eat meat on Friday. Today they can.
