Drupal 7 had been around for more than a decade, but it will have its "end of life" January 2025. During the pandemic, 7 received a handful of extensions to give folks more time to upgrade, but it will receive no more. Within less than a year from now, your Drupal 7 site will stop receiving all updates and it will become a potential security risk. But even long-term support (LTS) will only support core and some of the more popular modules.
If you're a CiviCRM site owner, or helping someone who is, you should have some kind of plan in place to get off Drupal 7, if you don't already. Soon. Like many of the CiviCRM experts, we at Freeform Solutions have experience helping site owners plan their moves off Drupal 7, whether it be to Drupal 10, WordPress, Backdrop or something novel. You can also start paying for Drupal 7 End of Life Support, but that option will only maintain the status quo.
