The next major version of Drupal is targeted to be released on June 3, 2020. Instead of building a radically new version of Drupal in a separate codebase, Drupal 9 is being built in Drupal 8. This means the upgrade experience will be smoother for core contributors, module authors, and site owners. But what does this mean for your site? Drupal 8 is the first major release to rely on significant third-party PHP dependencies. These dependencies, such as Symfony, Twig and Guzzle each have their own release and support cycles.
