Drupal 7 is moving along nicely, and is becoming increasingly stable. We just released a second alpha release, fixing a number of critical bugs, following our initial alpha release in January. Alpha releases are to give Drupalistas something to download and test, so they can report and help fix bugs.
When will we switch to betas? We will switch to betas when the upgrade path from Drupal 6 to Drupal 7 is working. Once we hit beta, we will become increasingly strict about accepting any more changes and we’ll also commit to making HEAD to HEAD upgrades work.
Finally, we’ll start rolling release candidates once the number of critical bugs is zero (or close to zero). To help us focus on critical bugs, we’re working on adding a ‘major’ severity level to our ticketing system, making the options ‘critical’, ‘major’, ‘normal’ and ‘minor’. ‘Major’ bugs would be really bad, but not necessarily block a release. For example, bugs that don’t prevent Drupal from working, or that only affect a fraction of the Drupal population would be prioritized for fixing in follow-up releases. Critical bugs are those that badly break Drupal, or that are a major regression compared to Drupal 6.
