Update module periodically checks for new versions of your site's software (including contributed modules and themes) and alerts you to available updates. To do this, anonymous usage statistics are sent to drupal.org and compared to the latest release information. Using this module is highly recommended, as it will alert you to important security updates, but may be disabled if you wish to avoid sending any information from your site. If you are considering disabling Update Status module, please read Drupal.org's privacy policy for more details.
