Nfpservices has ported CiviCRM GiftAid module to a CiviCRM GiftAid Extension for 4.2, so that it can be used in CiviCRM irrespective of the CMS. Before this release, only drupal users were able to use the module, as it was a drupal specific module, but after being ported as an extension, it can be used with Drupal, Joomla and Wordpress. The extension has been successfully tested in Drupal 7, Joomla and Wordpress.
