• An issue where the publishing API incorrectly sent 2 authentication tokens—one of which caused the API calls to fail— has been fixed.
• If you duplicate Book templates to create new books with existing topics, it used to produce large Resolved XML output files.
  
  To reduce publishing time and file size, we’ve now removed the extra data related to versions of duplicated objects. Your output will only include data for the version of the object that’s being used in the Book you're publishing.
