<li>SCRIPT did not work correctly with BLOB or CLOB data. Fixed.
</li><li>ORDER BY picked the wrong column if the same column name (but with a different table name)
was used twice in the select list.
</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.
