This is a Service Pack release of the MySQL Enterprise Server 5.1.
Bugs Fixed
Incompatible Change:
When auto_increment_increment is greater than
one, values generated by a bulk insert that reaches the maximum
column value could wrap around rather producing an overflow
error.
As a consequence of the fix, it is no longer possible for an
auto-generated value to be equal to the maximum BIGINT
UNSIGNED value. It is still possible to store that
value manually, if the column can accept it.
