          topic exists in the hierarchy and you can click any of the topics in the breadcrumb to
          open that particular page.
WebHelp Compatible with DITA-OT 3.x
Oxygen WebHelp has been tested and is compatible with the latest DITA Open
          Toolkit version 3.x.
XML Refactoring Operation to Migrate HTML Page Layout Files to Version 21
For custom publishing templates that were created in version 20.1 and that
          include custom HTML page layout files, a conversion procedure is required for the template
          to be compatible with version 21. A new XML Refactoring operation was added to make this
          conversion very easy. For details, see Converting Old Templates with
            HTML Page Layout Files to Version 21.
