This is critical update for DJ-Catalog2 component.
In 3.4.1 version there is a serious bug concerning CSV import function.
While updating records from CSV file, all images and downloadable files that were assigned to a record before the update might be erased. That's why we are suggesting to update DJ-Catalog2 to ver. 18.104.22.168 and not to use import function in older version 3.4.1.
