The latest Updates for r3 had been released to all customer environments. Besides providing prettier response to ease understanding we focused on supportive functions for the deployment process. From now on you can not only see, which roles you are able to deploy, you can also find out what are the actual sources configured per default for them (1).
Furthermore we updated and extended our Knowledge Base articles on the topic. Feel free to visit our Knowledge Base (2) or the handbook on r3 (3).
