2026.07.7

The largest release so far: Kindle books open, and every surface in the app has been redrawn.

Kindle books

.mobi, .azw and .prc files now open, and once open there is nothing to tell you which format
you are reading. They sit in the same library grid, with the same cover and progress badge, and the
same chapters, marks, notes and typography controls as an EPUB.

• Chapters come from the book's own table of contents, and from its page breaks when it has no
  contents page. A book with neither is still readable as one long chapter.
• Covers and titles are taken from the file's own metadata, so a shelf of Kindle books looks
  like a shelf of books rather than a list of filenames.
• A DRM-protected book is refused by name — Reader says the book is encrypted, in those words,
  rather than failing silently or blaming the file. Reader does not remove DRM.
• AZW3 (KF8) files are not read yet, and say so. Many .azw3 files carry an older copy of the
  book inside them; Reader would rather tell you it cannot read the good one than quietly show you
  the worse one.

The app, redrawn

One typeface, five greys, and one shape for every choice you make. Every value is a level this
particular panel can actually hold, so nothing on screen is dithered into a smear.

• The shelf holds twelve boards to a page and gets out of the way — search, filter and sort are
  hidden until you ask for them, and it holds still while you type instead of reshuffling under
  your hand.
• The reading chrome is one row of marks with the book's title beside the way out, and a
  running head below it carrying the chapter where a printed page puts it. In landscape that second
  row folds away and the chapter moves up, giving the page its height back.
• Typography is a sheet over the live page, in three tabs, so choosing a face or a size shows
  you the result on the words you were reading instead of after you close the panel.
• Chapters, marks and notes are one surface. They all answer "where am I in this book", and in
  print they are all back matter.
• A mark now carries its page's opening words, so a list of marks reads as a list of places
  rather than a list of numbers.
• Comics got the book's chrome, in the same shape, plus the ribbon — so learning one reader
  teaches you the other.

Things that were quietly wrong

• The chrome no longer slices a line of text in half. Opening it used to leave a strip of
  half-glyphs against the bar's rule; now the bar meets blank paper.
• The page steps back while the chrome is over it — one panel level, the smallest this display
  can hold flat — so the white bars read as the thing you are touching rather than as more page.
  The words themselves are untouched.
• The controls at the edges of the screen can be hit. The ‹ and › sat in boxes with 32dp of
  dead glass beside them, which is the exact strip a thumb lands on when you aim at a corner. They
  now reach the edge, without any mark moving.
• Book titles read as words, not as the filename someone happened to save.
• Portrait and landscape keep their own type settings. Set the size you like reading sideways
  and it stops fighting the size you like reading upright. Until you change something in an
  orientation, it follows the other one.

Also

A new launcher icon, and the shelf's two pictograms drawn in the app's own hand rather than
borrowed.

---

Two limits worth knowing. Comics are still portrait only and still have no zoom. And a
genuine RAR archive still does not open — a .cbr that is really a zip, which most are, does.

Your library, reading positions, marks, highlights and notes are all kept. A one-time database
upgrade runs on first launch, and page previews are rebuilt per book as you open them, since where
the pages fall has moved.
