- :doc:`Cart Library <libraries/cart>` changes include:
- - ``insert()`` now auto-increments quantity for an item when inserted twice instead of resetting it, this is the default behaviour of large e-commerce sites.
- - *Product Name* strictness can be disabled by switching the ``$product_name_safe`` property to FALSE.

- Added method ``get_item()`` to enable retrieving data for a single cart item.
- Added unicode support for product names.
- - ``update()`` now supports updating all properties attached to an item.
