It's September 1, and that means that the active development for the next release of Drupal is now moving into the bug-fixing phase. As Dries says:

Thanks to all the hard work we've done in the past three months, the next version of Drupal will have a lot of great improvements, including an installer, requirement checking for modules, a reorganization of the administration pages and file structure, a light-weight CCK, inclusion of jQuery and much more. We're also working on a new core theme (no guarantees it'll make it in time). With all that, I feel that, finally, the stars have aligned, and we're ready to call the next Drupal version, "Drupal 5.0.0". Thanks to all our contributors, Drupal 5.0.0 promises to be an amazing release!
