    you can use subquery to get the latest records for every serial_no. The result of the subquery is then join back on the original table so you can get the other columns.

    SELECT  a.*
FROM    tableName a
        INNER JOIN
        (
            SELECT serial_no, MAX(created) max_date
            FROM    tableName
            GROUP BY serial_no
        ) b ON a.serial_no = b.serial_no AND
                a.created = b.max_date
