Come 24 February 2016 and Drupal 6 will reach its end-of-life and will no longer have active community support. The newly-launched Drupal 8 and Drupal 7 will be the community’s focus and Drupal 6 will not receive security updates which are so important for the functioning of a website. It will also be a prudent move not to launch a new project with Drupal 6 and get stuck with a soon-to-be-obsolete Drupal version.
