It wasn't so long ago that Turtl content was live from the moment you started creating the document.
In 2019 we added various stages to the publish flow to allow you to choose when you're ready to publish. Your content now exists as a draft while you work on it and will only go live when you hit publish.
Also, the changes you make to a published document won't be live until you republish. Until then they'll be saved as unpublished changes.
