The ⋯ menu on a library card used to offer "Create newsletter draft", which asked you to fill in a title and body right there and could only produce a Substack draft — alongside three separate AI "Adapt for LinkedIn/Facebook/Mastodon" buttons that saved a detached new library piece you then had to go find. Both paths are replaced by a single "Repurpose to note" action: it drops the piece directly into Compose with its content pre-filled, and from there you pick the target platform exactly like on any other note.
