Row comparison now does compare field collations, e.g.
...
ROW('a','b','c) = ROW('A' collate latin1_bin,'b','c') returns 0
When a number is compared to a string, character sets and
collations are not aggregated. e.g. this returned error in 4.1.0:
SELECT 1=_latin2'1';
because character sets was aggregated, and 1 was considered as
a string of latin1 charset during this aggregation.
