- Change in structure of frozen coursecategories hash within configuration.db.
  hash can contain:
  togglecats => scalar (dom or crs)
  categorize => scalar (dom or crs)
  cats => HASH (hash of course categories).
- togglecats determines whether setting of "hidefromcat" course parameter is by CC in "Set Course Environment", or by DC in "Modify course"
- categorize determines whether manual setting of category for a course is by CC in "Set Course Environment", or by DC in "Modify course"
- cats contains the hash of categories:
e.g.,
          'cats' => {
                      'instcode::0' => '0',
                      'Schools::0' => '3',
                      'Colleges::0' => '1',
                      'Departments::0' => '2'
                    },
If there are any developers who created categories for testing purposes in the past month using domainprefs.pm 1.52 and later, these will need to be recreated using the "Domain Configuration" interface.
