Update: Drupal 7.0 Alpha 4 is available now!
Our second Drupal 7 alpha version was released just over a month ago. Today, we're proud to announce the release of the third alpha version of Drupal 7.x for your further testing and feedback. The first alpha announcement provided a comprehensive list of improvements made since Drupal 6.x, so in this announcement we'll concentrate on how you can help ensure that Drupal 7 is released as soon as possible and is as rock solid as the previous Drupal releases that you've grown to love!
The release notes contain a list of the biggest changes. The most notable change for developers is Drupal 7 now ships with jQuery 1.4 and jQuery UI 1.8. We've also fixed a number of critical issues since the previous alpha, most importantly one that caused passwords to be stored in plain-text under certain conditions. Oops. :P This is a great time to reiterate...
This alpha version should not be used for production sites. We've resolved most errors reported so far, but there are outstanding known issues (including security issues) and most likely some problems that have not been reported as of yet. It is expected that there will be a few beta versions and at least one release candidate before Drupal 7.0 is finalized. You can help us reach the final release date sooner by testing this alpha and providing feedback.
