Important: You must run the
            mysql_fix_privilege_tables script when
            you upgrade to this version! This is needed because of the
            new GRANT system. If you don't do this,
            you will get Access denied when you try
            to use ALTER TABLE, CREATE
            INDEX, or DROP INDEX.
          
            GRANT to allow/deny users table and
            column access.
          
            Changed USER() to return a value in
            user@host format. Formerly it returned
            only user.
          
            Changed the syntax for how to set
            PASSWORD for another user.
          
            New command FLUSH STATUS that resets most
            status variables to zero.
          
            New status variables: aborted_threads,
            aborted_connects.
          
            New option variable: connection_timeout.
          
            Added support for Thai sorting (by Pruet Boonma
            <pruet@ds90.intanon.nectec.or.th>).
          
Slovak and Japanese error messages.
Configuration and portability fixes.
            Added option SET SQL_WARNINGS=1 to get a
            warning count also for simple (single-row) inserts.
          
            MySQL now uses SIGTERM instead of
            SIGQUIT with shutdown to work better on
            FreeBSD.
          
            Added option \G (print vertically) to
            mysql.
          
            SELECT HIGH_PRIORITY ... killed
            mysqld.
          
            IS NULL on a
            AUTO_INCREMENT column in a LEFT
            JOIN didn't work as expected.
          
            New function MAKE_SET().
