• Shelf of shelves: the stack count badge now shows on its shelves' tiles, under Folders only or All stacks (#527), and Random book on "current shelf only" picks from the shelves inside it (#528).
• Spines: face-out covers keep the theme's border, so a custom Border colour no longer outlines them apart from the book.
• Fix: the section labels on Spines shelves show your Folder overlay colour instead of a grey (#525).
• Fix: Calibre metadata is found on a Kobo whose home folder was never set (#517).
• Fix: About now warns about another copy of bookshelf in a custom plugin folder.
