• Decades: a new grouped source (shelf settings > Source > Grouped > Decades) stacks your books by the decade they were published, with Unknown last. "A decade" makes a shelf of just one.
• %published{format}: the full publication date in your own layout, like %published{%d %B %Y}. A book whose date has no month or day shows the shorter form.
• Book sizes in a spine shelf's settings: Varied, or Same to stand every book at one size.
• Series boxes can now be Cover, Plain (no picture) or Spines (the books spine-out, with the first cover printed across them) (#577).
• Series boxes in Covers and List too (long-press the shelf > View mode > Series boxes): each series gets one tile, on a shelf of books and inside an author or any other group (#503).
• Spine text size: Bookshelf settings > Text size > Spine text. Spines get thicker to fit larger text.
• Inside a Shelf of shelves, tap the shelf's name in the breadcrumb to open its settings.
• Shelves from other plugins' sources can now use Spines view, when the plugin offers it (#588).
• Genres from calibre only, under Read calibre metadata.calibre: genres come from calibre's tags alone, without the book file's old ones (#583).
• The top panel's description can be justified (#586, thanks @ferorborja).
• List view rows no longer have the small arrow on the right (#589).
• Faster page turns: the next pages are made ready while you read, and turning back to a page you just left is much quicker.
• Faster shelf switching and startup, most noticeable on older Kindles.
