Today, 13 months after the Drupal 5.0 release, we released Drupal 6.0 to the world. Read more about Drupal 6.0 in the official release announcement or just look at the What is new in Drupal 6.0?" screencast (30 min) that we prepared.
Needless to say, Drupal 6 is our most exciting release to date. It is a legendary piece of work, by the community, for the community. Thanks to the hundreds of Drupal contributors for their tireless work and commitment!
