The second alpha version of Drupal 7.x was released on February 23, 2010. This version is a test version that was released for further testing and feedback. It is important to note that this alpha version should not be used for production sites. 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.

We will be using Drupal 6 for this class until Drupal 7.0 is finalized and all the modules we use are available.
