Drupal 6 has been in a code freeze for more than 6 months and is almost ready to be released now. We're only a few bug fixes away from the first final Drupal 6.0 release. Therefore, I just created the DRUPAL-6 CVS branch for Drupal core. This means that while Drupal 6 is being finalized and we prepare for the Drupal 6.0 release, we'll also start accepting new features and improvements for Drupal 7, the next major version of Drupal.

For maximum effectiveness, feature requests for Drupal 7, should go in the the list of feature requests. In my State of Drupal presentation in Barcelona I hinted about what would be the killer Drupal 7 release according to a survey I conducted. While that list is not exclusive and nothing but a wishlist (not a deliverable), it might be worth a look if you want to help shape the future of Drupal.

If you don't want to watch the entire video, the community's collective wishlist looks like this:

1. Better media handling
2. Custom content types in core
3. WYSIWYG editor
4. Better performance
5. Better tools to structure/organize content
6. Basic Views like module
7. Automatic upgrade functionality
8. Improved node access system
9. Better internal APIs
10. Better external APIs (import/export, web services)
11. Usability

Just like with the Drupal 6 branch, I probably won't pick a Drupal 7 branch maintainer until we're a few weeks or months down the road and people have picked up core development.
