Library of America - Joan Didion: Memoirs and Later Writings

I just received the newest and final Library of America collection of Joan Didion's writings, but it does not include her most recent and final work, Let Me Tell You What I Mean (2021). I haven't read LMTYWIM yet, but from my preliminary research it includes essays that were previously unpublished in a collection and are therefore missing from the Library of America editions.

So, what gives? Does anyone have any insight as to why this might be? It's frustrating that these are putatively her collected works and yet they are missing one!
