I had auto-update turned on and now I'm regretting it. Drupal 7 was just released - yay for getting it in so fast! But it'll be a long time before I can convince anybody to use it - there's still a lot of work and debugging to do. I'll probably be installed Drupal 6 sites for months. But Drupal 6 is gone now! How can I get it back? Is that possible?
