RC4 is now available for download. RC3 had a very brief life after we discovered some glitches but we've been hard at it to get these fixed and after a lot of work we think we're there.
RC4 includes some significant fixes to a number of issues reported after the switch to using apps at the last release. Thanks to all of you who are posting issues on the drupal.org issue queue for Open Outreach as that really helps us improve the distribution.
Nedjo has also tackled some major re-factoring of how roles are generated in all of the Debut features. To do so, he has created a new helper module--Apps compatible--and deprecated Debut.
Improvements have been made to Debut Event so that it now includes a vocabulary for event types and includes exposed filtering and a legend. Open Outreach generates the first three terms for this vocabulary to get users started. We've also added an iCal feed. For older version users, this means two additional modules will be required: Better Exposed Filters and Date iCal.
As always, if you're running an update be sure to back up your site and follow the instructions in our user documentation section.
