This is a maintenance release of the 4.1 version, mainly fixing recently discovered bugs. This release includes:
:item1: The server now issues a warning when ‘lower_case_table_names=2’ and the data dictionary is on a case-sensitive filesystem
:item1: The server now issues a warning to the error log when it encounters older tables that contain character columns that might be interrupted by newer servers to have a different column length.
:item1: InnoDB: A shared record lock (‘LOCK_REC_NOT_GAP’) is now taken for a matching record in the foreign key check because inserts can be allowed into gaps.
