The team behind the popular open-source CMS Drupal is urging admins to update their sites to ward off a nasty bug that could leave their sites “highly compromised” to attackers, according to the organisation.
Backdrop CMS is based on the works of Drupal 7. It can be viewed as an extended version of Drupal 7 and branched off from Drupal 8 during the development cycle at a time when Drupal was getting completely refactored to include some Symfony2 framework and moving towards OOP while maintaining the Drupal UI and concepts.
Open Social is a distribution for building social communities & intranets. The distribution is positioned as the successor of Drupal Commons, taking full advantage of the new possibilities of Drupal 8.
