    -  Changed humanize to include a second param for the separator.
    -  Refactored ``plural()`` and ``singular()`` to avoid double pluralization and support more words.
    -  Added an optional third parameter to ``force_download()`` that enables/disables sending the actual file MIME type in the Content-Type header (disabled by default).
+   -  Added a work-around in force_download() for a bug Android <= 2.1, where the filename extension needs to be in uppercase.
+   -  form_dropdown() will now also take an array for unity with other form helpers.

    -  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).
+   -  Added a constructor to the DB_result class and moved all driver-specific properties and logic out of the base DB_driver class to allow better abstraction.
+   -  Removed limit() and order_by() support for UPDATE and DELETE queries in PostgreSQL driver. Postgres does not support those features.
+   -  Removed protect_identifiers() and renamed _protect_identifiers() to it instead - it was just an alias.
+   -  MySQL and MySQLi drivers now require at least MySQL version 5.1.
+   -  db_set_charset() now only requires one parameter (collation was only needed due to legacy support for MySQL versions prior to 5.1).
 
 -  Libraries
 
    -  Added max_filename_increment config setting for Upload library.
    -  CI_Loader::_ci_autoloader() is now a protected method.
-   -  Modified valid_ip() to use PHP's filter_var() when possible (>= PHP 5.2) in the :doc:`Form Validation library <libraries/form_validation>`.
    -  Added custom filename to Email::attach() as $this->email->attach($filename, $disposition, $newname)

+   -  Form Validation library now allows setting of error delimiters in the config file via $config['error_prefix'] and $config['error_suffix'].

+   -  Added function set_data() to Form_validation library, which can be used in place of the default $_POST array.
