Still on Drupal 7? Security support for Drupal 7 ended on 5 January 2025. Please visit our Drupal 7 End of Life resources page to review all of your options.
Important change: The default retention period has changed from 6 hours to "forever." This change should affect very few sites, as retention periods would normally be configured rather than falling back on the default value. If for some reason you were relying on the default retention period rather than actually configuring it, you can visit the settings page at admin/config/people/ip_anon to configure it.
