YAD7 is a community-sponsored answer to The Drupal Organization's announcement of End-of-Life for Drupal 7. Because Drupal is open-source, the community has the opportunity to decide whether to go along with the main-line branch (currently in version 8 and moving towards version 9), or whether to pursue a different course. Given that there are about a million Drupal 7 sites, and that the migration path to Drupal 8 involves a profound redesign of existing sites, the Drupal community needs a more compatible migration path forward.
