The book always had a lock. But I think gaining approval with Shadowheart if you manage to unlock it yourself is new, since I think it's normally expected for her to unlock it.
Harpy nest always had the book and note there. One of the books which has redacted names talking about the island nation of Chult is actually referring to the villain of one of the more recently released campaigns, Acererak from Tomb of Annihilation. There's speculation that this book's existence points to the idea that he might be playing some role in BG3 later. I only keep this information in the back of my mind because I did briefly play in that campaign as part of my first ever tabletop sessions that ended in failure (as in a near total party wipe near the end of the campaign that only my character survived), so my character has some major personal beef with him.
