We have just raised 3.3.0.11973 to our new release operating system. This revision is compatible with future data formats and will therefor act as fallback for our next operating system 4.0.
3.3.0.11973 Release is functionally identical with 3.3.0.11973 Public Beta. So no need to upgrade, if that public beta is already installed. Former builds should be upgraded to 11973.
