 			<li>Semantic change to db->version() function to allow a list of exceptions for databases with functions to return version string instead of specially formed SQL queries. Currently this list only includes Oracle and SQLite.</li>
 			<li>Fixed a bug where driver specific table identifier protection could lead to malformed queries in the <kbd>field_data()</kbd> functions.</li>
