- It now auto-increments quantity's instead of just resetting it, this is the default behaviour of large e-commerce sites.
- Product Name strictness can be disabled via the Cart Library by switching "$product_name_safe"

- 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 (#11, #183, #863) - CI_Form_validation::_execute() silently continued to the next rule, if a rule method/function is not found.
