I am a newbie - just wanted to get that out of the way. I am building my first Drupal site with Ubercart 3.3 and Drupal 7.15 to sell products that have associated file downloads. When updates are made to the file downloads I would like to 'Add a new feature' to the product with the updated files and have this new file download appear to users who have already purchased the product. I have not been able to make this happen. I see the module http://drupal.org/project/uc_file_retro has tried to address this issue but it is not compatible with Durpal 7.x. Any recommendations would be greatly appreciated.
