Blackboard recently made updates to Blackboard SaaS with the "Ultra Base Navigation" and the "Ultra Experience" that is somewhat compatible with Respondus 4.0.8.09
For Blackboard SaaS with the "Ultra Base Navigation", publishing to and retrieving from courses continues to work the same as with Blackboard Learn 9.1 courses.
For Blackboard SaaS with the "Ultra Experience", publishing to and retrieving from "Original View" courses continues to work the same as with Blackboard Learn 9.1 courses. Retrieving questions from Ultra View course might work depending on updates from Blackboard Support.
Currently, for "Ultra View" courses, the "Additional options for Exam/Survey" with "Apply Settings" and "Link Exam to Content Area and make available" are not available. By deselecting these settings, the file will publish to a hidden "Undeployed Tests" folder. Also, Blackboard Ultra will drop several question types from the file.
Currently, full support for Blackboard Ultra Base Navigation and Blackboard Ultra requires new APIs and web services to integrate with Respondus and other external applications. Once Blackboard fully develops the necessary APIs and web services, Respondus Product Management plans to fully support Blackboard Ultra with Respondus 4.0.
