Fixed mysqld crash on extremely small
            values of sort_buffer variable.
          
            Fixed a bug in privilege system for GRANT
            UPDATE on column level.
          
            Fixed a rare bug when using a date in
            HAVING with GROUP BY.
          
            Fixed checking of random part of WHERE
            clause. (Bug#142)
          
            Fixed MySQL (and myisamchk) crash on
            artificially corrupted .MYI files.
          
            Security enhancement: mysqld no longer
            reads options from world-writeable config files.
          
            Security enhancement: mysqld and
            safe_mysqld now only use the first
            --user option specified on the command
            line. (Normally this comes from
            /etc/my.cnf)
          
            Security enhancement: Don't allow BACKUP
            TABLE to overwrite existing files.
          
            Fixed unlikely deadlock bug when one thread did a
            LOCK TABLE and another thread did a
            DROP TABLE. In this case one could do a
            KILL on one of the threads to resolve the
            deadlock.
          
            LOAD DATA INFILE was not replicated by
            slave if replicate_*_table was set on the
            slave.
          
            Fixed a bug in handling CHAR(0) columns
            that could cause incorrect results from the query.
          
            Fixed a bug in SHOW VARIABLES on 64-bit
            platforms. The bug was caused by incorrect declaration of
            variable server_id.
          
            The Comment column in SHOW TABLE STATUS
            now reports that it can contain NULL
            values (which is the case for a crashed
            .frm file).
          
            Fixed the rpl_rotate_logs test to not
            fail on certain platforms (e.g. Mac OS X) due to a too long
            file name (changed slave-master-info.opt
            to .slave-mi).
          
            Fixed a problem with BLOB NOT NULL
            columns used with IS NULL.
          
            Fixed bug in MAX() optimization in
            MERGE tables.
          
            Better RAND() initialisation for new
            connections.
          
            Fixed bug with connect timeout. This bug was manifested on
            OS's with poll() system call, which
            resulted in timeout the value specified as it was executed
            in both select() and
            poll().
          
            Fixed bug in SELECT * FROM table WHERE datetime1 IS
            NULL OR datetime2 IS NULL.
          
            Fixed bug in using aggregate functions as argument for
            INTERVAL, CASE,
            FIELD, CONCAT_WS,
            ELT and MAKE_SET
            functions.
          
            When running with --lower-case-table-names
            (default on Windows) and you had tables or databases with
            mixed case on disk, then executing SHOW TABLE
            STATUS followed with DROP
            DATABASE or DROP TABLE could
            fail with Errcode 13.
          
            Fixed bug in logging to binary log (which affects
            replication) a query that inserts a NULL
            in an auto_increment field and also uses
            LAST_INSERT_ID().
          
            Fixed bug in mysqladmin --relative.
          
            On some 64 bit systems, show status
            reported a strange number for Open_files
            and Open_streams.
