<h2>Change Log</h2>
<h3>Version 1.0 (Current)</h3>
<h3>Version 1.0 / 2007-02-TODO</h3><ul>
<li>SCRIPT did not work correctly with BLOB or CLOB data. Fixed.
</li><li>When a subquery was used in the select list of a query, and GROUP BY was used at the same time,
a NullPointerException could occur. Fixed.
</li><li>ORDER BY did not work when DISTINCT was used at the same timein some situations. Fixed.
</li><li>When using IN(...) on a case insensitive column (VARCHAR_IGNORECASE),
an incorrect optimization was made and the result was wrong sometimes.
</li></ul>
<h3>Version 1.0 / 2007-01-30</h3><ul>
<li>Experimental online backup feature using the SQL statement BACKUP TO 'fileName'.
