Resources cross-listed into a parent category (one with sub-categories) were not shown in that category’s list
Pending and deleted resources visibility rules were not applied to resources listed in cross-listed categories
The “Display in following categories” picker now only lists categories you can view and add resources to, and the selection is checked on the server when adding or editing a resource (existing cross-listings you cannot see are kept)
The “fromcat” parameter on resource links could expose a hidden category, it is now only used when the category is viewable and the resource is cross-listed into it
Category counters could be wrong after a cross-listed resource was approved, rejected, deleted, restored or moved
