- Added boolean data type support in escape().
+ - Added update_batch() support.
- 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 internal method _protect_identifiers() to it instead - it was just an alias.

- Fixed a bug in the :doc:`Session Library <libraries/sessions>` where a PHP E_NOTICE error was triggered by _unserialize() due to results from databases such as MSSQL and Oracle being space-padded on the right.
- Fixed a bug (#501) - set_rules() to check if the request method is not 'POST' before aborting, instead of depending on count($_POST) in the :doc:`Form Validation Library <libraries/form_validation>`.
- Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.
-- Fixed a bug in PostgreSQL's escape_str() where it didn't properly escape LIKE wild characters.
+- Fixed a bug (#136) - PostgreSQL, MySQL and MySQLi's escape_str() method didn't properly escape LIKE wild characters.
- Fixed a bug in the library loader where some PHP versions wouldn't execute the class constructor.
- Fixed a bug (#88) - An unexisting property was used for configuration of the Memcache cache driver.

- Fixed a bug (#319) - SQLSRV's affected_rows() method failed due to a scrollable cursor being created for write-type queries.
