Two critical bugs have been fixed in this release. The first broke cron functionality and the second wouldn't allow synchronization to occur if a Drupal user didn't exist for every CiviCRM contact. Thanks to rallycivic for bringing to my attention these issues and for solving the latter!
Initial Imagefield2 and Imagecache2 integrations as well as some css generations and usability fixes. Imagefield and imagecache (1) all still work properly, however if you've got this running right now you may need to reset your content type admin page. I ran into some issues with imagefield and imagecache2 and would like some feedback from anyone who can play with it.
