Nov. 2, 2021 marks a first for Drupal.

Never before has a Drupal version end-of-life date signaled a true hard stop, with no possibility of extended support and no commercial vendors that are in a position to provide off-grid security maintenance and bug fixes. 

At issue is Drupal 8’s Symfony 3 dependency, which was also decommissioned on Nov. 2, 2021.
