Check for updates
Select how frequently you want to automatically check for new releases of your currently installed modules and themes.
Whenever your site checks for available updates and finds new releases, it can notify a list of users via email. Put each address on a separate line. If blank, no emails will be sent.
Email notification threshold
You can choose to send email only if a security update is available, or to be notified about all newer versions. If there are updates available of Drupal core or any of your installed modules and themes, your site will always print a message on the status report page. If there is a security update, an error message will be printed on administration pages for users with permission to view update notifications.
