Change Log

<h3>
Version 1.0 (Current)
</h3>
<h3>
Version 1.0 / TODO
</h3><ul>
<li>
SQLException.getCause of the now works for JDK 1.4 and higher.
</li><li>
If the index file was deleted, an error was logged in the .trace.db file. This is no longer done.
</li><li>
The Portuguese (Europe) translation is available. Thanks a lot to Antonio Casqueiro!
</li><li>
The error message for invalid views has been improved (the root cause is included in the message now).
</li><li>
IN(SELECT ...) was not working correctly if the subquery returned a NULL value. Fixed.
</li><li>
DROP ALL OBJECTS did not drop constants.
</li><li>
DROP ALL OBJECTS dropped the role PUBLIC, which was wrong. Fixed.
</li><li>
CASE was parsed as a function if the expression was in (). Fixed.
</li><li>
When ORDER BY was used together with DISTINCT, it was required to type the column
name exactly in the select list and the order list exactly in the same way.
This is not required any longer.
</li></ul>
<h3>
Version 1.0 / 2007-03-04
</h3><ul>
<li>
System sequences (automatically created sequences for IDENTITY or AUTO_INCREMENT columns) are now
random (UUIDs) to avoid clashes when merging databases using RUNSCRIPT.

Recovery for BLOB / CLOB: support functions

Better support large transactions, large updates / deletes: use less memory

</li><li>
Max memory rows / max undo log size: use block count / row size not row count
</li><li>
Index summary is only written if log=2; maybe write it also when log=1 and everything is fine (and no in doubt transactions)
</li><li>
Support 123L syntax as in Java; example: SELECT (2000000000*2)

Better support large transactions, large updates / deletes: allow tables without primary key

Implement point-in-time recovery

Memory database: add a feature to keep named database open until 'shutdown'

Harden against 'out of memory attacks' (multi-threading, out of memory in the application)
