The Drupal 6.1 release is out. Interestingly, Drupal 6 users are encouraged to do a full update – that is, to upload every single file to their server again. They have a patch updater, but that only plugs the security holes. And that updater leaves Drupal “in an unversioned state, confusing the update status module”. There’s no set of files that can upgrade Drupal 6.0 to 6.1 cleanly, the way it’s easy to update WordPress by simply uploading a few files.
Drupal really has a long way to go to get up to the usability of WordPress.
