- MySQLi driver now supports persistent connections when running on PHP >= 5.3.
- Added dsn if the group connections in the config use PDO or any driver which need DSN.
- Improved PDO database support.
- - An optional database name parameter was added db_select().
+ - Added Interbase/Firebird database support via the "interbase" driver
+ - Added an optional database name parameter to db_select().
+ - Replaced the _error_message() and _error_number() methods with error(), that returns an array containing the last database error code and message.
+ - Improved version() implementation so that drivers that have a native function to get the version number don't have to be defined in the core DB_driver class.
+ - Improved support of the PostgreSQL driver, including:
+ - pg_version() is now used to get the database version number, when possible.
+ - Added db_set_charset() support.
+ - Added _optimize_table() support for the :doc:`Database Utility Class <database/utilities>` (rebuilds table indexes).

- _execute() now considers input data to be invalid if a specified rule is not found.
- Removed method is_numeric() as it exists as a native PHP function and _execute() will find and use that (the 'is_numeric' rule itself is deprecated since 1.6.1).
- Native PHP functions used as rules can now accept an additional parameter, other than the data itself.

- Fixed a bug in PDO's _version() method where it used to return the client version as opposed to the server one.
- Fixed a bug in PDO's insert_id() method where it could've failed if it's used with Postgre versions prior to 8.1.
- Fixed a bug in CUBRID's affected_rows() method where a connection resource was passed to cubrid_affected_rows() instead of a result.
- Fixed a bug (#638) - db_set_charset() ignored its arguments and always used the configured charset and collation instead.
