I rely on cumulative flow diagrams to help manage my project. I currently have a separate db that tracks state changes in issues for the purposes of generating CFDs but it is a pain to maintain. Ideally I would be able to grab timestamps of issue status changes from YouTrack, however, I can't figure out how to do that. Does anybody know if there is a data dump (export to csv for example) or REST call that would give me access to an issue's history? Is there some other way to get at this information?
