Drupal is a content management system (CMS) built on the PHP and MySQL combination (detailed requirements here). I've been working with the latest version since its release at the beginning of this month.
I'm pleased to announce the first ever world-wide Drupal Developer TeleConference! All Drupal developers, those wishing to become developers or just those with an interest in Drupal's development process are encouraged to attend.
Get your text editors started: the next Drupal code freeze will be September 1st. This means all new features for the next Drupal release need to make it into the development version ("CVS HEAD") no later than August 31st.
