You have been using it for a long time, right? Have you found any issues in the case when you previously successfully generated a site using an older version, but then install a newer version in a different machine, and you try to generate the site with the "old" source? That unfortunately has happened to me with other static site generators (breaking changes between versions with no automatic way to resolve them or thorough documentation on the changes to make to the source).
