Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
The module is without any critical bugs and at beta 7, since 2009-Jan-24.
Please, get it out of beta, so Drupal's security community:
1) starts monitoring for any security issues within the module and
2) can warn the community (e.g. via http://lists.drupal.org/mailman/listinfo/security-news), if such issues arise.
