Its been long wait, but second release candidate of 6 line is here! you can download it here: http://ftp.drupal.org/files/projects/drupal-6.0-rc2.tar.gz

There are still known issues, that being solved rigt now but before that:

we have fixed various issues including the security fixes that come with Drupal 5.6 and others involving caching filtered content, menu item inheritance, missing breadcrumbs, better error reporting in the installer and updates, some translatability issues and lots of code style cleanups, and other small fixes.

The most notable usability improvement since Drupal 6.0 RC1 is that the files directory is now automatically created in sites/default.

Developers promise to release Drupal 6 asap
