the change was necessary to get DROP FOREIGN KEY to replicate. It was a bug
fix, that is why I put the change to a minor MySQL version:
"
Fixed a bug: generate FOREIGN KEY constraint identifiers locally for each
table, in the form db_name/tbl_name_ibfk_number. If the user gives the
constraint name explicitly, then remember it. These changes should ensure
that foreign key id's in a slave are the same as in the master, and DROP
FOREIGN KEY does not break replication. (Bug #2167)
"
I agree that in the future, we have to try to make less changes to stable
versions of MySQL, and put new features only in new major versions.
