KOReader 2025.10 “Ghost”

· Filed under Software

As one of the maintainers of KOReader, a versatile a document and image viewer, I’m proud to announce the latest release.

Ghost

Apologies, I don’t have much time to write release notes today. As usual there’s been quite a bit of activity. One of the most visible changes is that if you like stable page numbers, artificially generated stable page numbers can now be easily configured under navigation (image) → Settings → Stable page numbers.

Keeping in tune with not spending too much time on release notes, here’s a copy of the included help text:

By default, one screen equals one page. Any change in the book’s formatting will therefore result in renumbering: new total pages, different chapter lengths, new locations in TOC and bookmarks, etc.

Select stable page numbers if you prefer page numbers that are independent of layout settings and consistent across devices:

  1. Publisher page numbers (℗): normally equivalent to a specific physical edition. Only available if supplied by the publisher.
  2. Characters per page: a page will be counted for this amount of characters (sometimes called logical or synthetic page numbers). Use this if no publisher page numbers are available or if you prefer to have consistent page lengths for all books.

Since stable page numbers can start anywhere on the screen, you can choose to display them in the margin, regardless of other settings.

‘Stable page number list’ shows a table of all stable page numbers and their corresponding screen page numbers.
