We want to have a work flow for one of our confluence spaces that will require an approval from a partner before the changes go live. I think the best way to do this would be to make unpublished changes and export them as a pdf and email them for approval and once approved publish the changes. However, I can not work out how to export the page as is with unpublished changes, is this possible? I see that when you preview changes you don't get any of those options.
