Filter by custom status - Find matching books from the Status filter menu. Smarter book count - When you search or filter, the library header now shows your total books and how many match (e.g. '24 Books • 6 Filtered'). Improved import & export - Custom statuses in your CSV import correctly when you re-import your library. Please send all feedback and suggestions via our contact page if there are features or updates you'd like to see."

You choose - Review the possible duplicate book, then Add anyway or Cancel to go back and amend the details. ISBN protection unchanged - Duplicate ISBNs are still blocked so each book keeps a unique ISBN."
