The test suite now tests all reachable
            BDB interface code. During testing we
            found and fixed many errors in the interface code.
          
            Using HAVING on an empty table could
            produce one result row when it shouldn't.
          
Fixed the MySQL RPM so it no longer depends on Perl5.
            Fixed some problems with HEAP tables on
            Windows.
          
            SHOW TABLE STATUS didn't show correct
            average row length for tables larger than 4G.
          
            CHECK TABLE ... EXTENDED didn't check row
            links for fixed size tables.
          
            Added option MEDIUM to CHECK
            TABLE.
          
            Fixed problem when using DECIMAL() keys
            on negative numbers.
          
            HOUR() (and some other
            TIME functions) on a
            CHAR column always returned
            NULL.
          
Fixed security bug in something (please upgrade if you are using an earlier MySQL 3.23 version).
Fixed buffer overflow bug when writing a certain error message.
            Added usage of setrlimit() on Linux to
            get -O --open-files-limit=# to work on
            Linux.
          
            Added bdb_version variable to
            mysqld.
          
Fixed bug when using expression of type:
SELECT ... FROM t1 LEFT JOIN t2 ON (t1.a=t2.a) WHERE t1.a=t2.a
            In this case the test in the WHERE clause
            was wrongly optimised away.
          
            Fixed bug in MyISAM when deleting keys
            with possible NULL values, but the first
            key-column was not a prefix-compressed text column.
          
            Fixed mysql.server to read the
            [mysql.server] option file group rather
            than the [mysql_server] group.
          
            Fixed safe_mysqld and
            mysql.server to also read the
            server option section.
          
            Added Threads_created status variable to
            mysqld.
