Update: Drupal 7.0 Alpha 3 is available now!
Our first Drupal 7 alpha version was released just over a month ago. Today, we're proud to announce the release of the second 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 most notable change for developers is moving
$form_state. This makes field forms more resilient to form_alters and debugging became a lot less tedious. Comment body became a field and new fields can be added to comments through the field UI module. And congratulations to the docs team and associated helpers for their outstanding work in enhancing and correcting lots of API documentation this release.
We've also fixed a number of issues since the previous alpha, most importantly one that caused all files to be deleted after six hours. Oops. :P This is a great time to reiterate...
It is important to note that 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 at least one more alpha version followed by 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.
