It would be quite helpful to everyone (following a book series or not) if Hardcover Librarians are also able to mark an unpublished book "unreleased" without needing to provide a tentative release date.

I noticed that the gray tag, "unreleased," only appears beside the title when there's a given tentative date. It's an informative little feature that I appreciate very much! However, there are cases in which future works are already added to Hardcover database despite having no official release date yet; this is likely due to prior announcements made by authors/publishers, thus readers ended up putting their books waaay ahead of time.

If librarians can easily mark a book unreleased without an accurate date, perhaps the resulting notice would go like "Publication TBA"? Or something else. Whatever works for the devs, of course. I think it would clear up any confusion! 😄
