I've just released the stable 2.0 version of the Drupal Webform CiviCRM Integration module and wanted to share some of the cool new things you can do with it.
Version 1, which I wrote earlier this year, was basically built for a single purpose: you could have a user fill out a webform, and their contact record (name, address, email, etc.) would be created/updated and an activity of the form submission would be logged. That alone is pretty darn useful, but suggestions from users, the advent of API v3, and a commission from the core team got me setting sights higher for the next release.
