As of 31st August 2011 the current version of the 7-series Drupal Content Management System software is v7.8 – this was in the words of its creators "a maintenance release of the Drupal 7 series. Only bugfixes and small API improvements have been committed. No security fixes are included in this release. New features are only being added to the forthcoming Drupal 8-series release." Upgrading to the latest version for your online software is generally wise. More information and links to a free download can be found here: http://drupal.org/drupal-7.6/
