One didn't get an error message if mysqld couldn't open the privilege tables.

SET PASSWORD FOR ... closed the connection in case of errors (bug from 4.0.3).

Added LOCK TABLES and CREATE TEMPORARY TABLES privilege on the database level. You must run the mysql_fix_privilege_tables script on old installations to activate these.

In SHOW TABLE ... STATUS, compressed tables sometimes showed up as dynamic.

SELECT @@[global|session].var_name didn't report global | session in the result column name.

Fixed a bug from 4.0.2 that caused REPAIR TABLE and myisamchk --recover to fail on tables with duplicates in a unique key.
