Starting with the 3400.3.0 release, New Box View will be the default service (instead of Crocodoc) for all new Blackboard Learn installations. If your institution decided not to transition to New Box View and is upgrading to a more recent version of Blackboard Learn, this change won't affect you unless you are starting with a fresh install for the new target instance.
