Our final Drupal 7 alpha version was released about three weeks ago. Today, we're proud to announce the first beta version of Drupal 7.x for your further testing and feedback!
The jump between alpha to beta means the following:
We think that we have resolved all critical data loss and security bugs in Drupal 7.
We think that our APIs are now frozen enough so that contributed module and theme authors can start (or pick up again) their #D7CX pledges.
We think that we have caught and fixed most of the problems with the upgrade path. We were able to successfully upgrade a copy of the Drupal.org database to Drupal 7.
That said, we definitely still have some bugs to shake out, and we need your help to find them! Especially new folks who haven't taken Drupal 7 for a spin yet. So please, do so, and let us know what bugs you find in the "Drupal core" issue queue (Please search incoming issues before filing).
Finally! On his birthday, was released the alpha release of Drupal 7!
After nearly two years of development, we are proud to announce the release of the first alpha version of the family Drupal 7.x. This alpha includes a huge number of new features and new improvements for users and for developers.
