- Renamed internal method ``_escape_identifiers()`` to ``escape_identifiers()``.
- Updated ``escape_identifiers()`` to accept an array of fields as well as strings.
- MySQL and MySQLi drivers now require at least MySQL version 5.1.
+ - Added a ``$persistent`` parameter to ``db_connect()`` and changed ``db_pconnect()`` to be an alias for ``db_connect(TRUE)``.
- ``db_set_charset()`` now only requires one parameter (collation was only needed due to legacy support for MySQL versions prior to 5.1).
- - ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` / ``db_pconnect()`` instead of only when initializing.
+ - ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` instead of only when initializing.
- Replaced the ``_error_message()`` and ``_error_number()`` methods with ``error()``, which 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.
- Added capability for packages to hold *config/database.php* config files.
