Yes, and oh yes there is, for the version where it changed, in ONEWS:
o Subassignments involving NAs and with a replacement value of
length > 1 are now disallowed. (They were handled
inconsistently in R < 2.0.0, see PR#7210.) For data frames
they are disallowed altogether, even for logical matrix indices
(the only case which used to work).
