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 (<img width="24" height="24" valign="middle" alt="image" src="https://github.com/user-attachments/assets/1f139c48-a3d1-433c-8531-08bc7a3e3655" />) → 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 charact

A random sampling from some new features: full-text search now has a start page (<https://github.com/koreader/koreader/pull/13798>); the OPDS browser has gained syncing and "facets" (<https://github.com/koreader/koreader/pull/14089>), which will allow you to change the sort order among other things on supporting feeds. Dictionaries are now more fiddly (the good kind, with presets, <https://github.com/koreader/koreader/pull/13774>), and cloud storage downloads offer a progress bar (<https://github.com/koreader/koreader/pull/13650>). CBR comics (<https://github.com/koreader/koreader/pull/13780>), and of course more supported devices as always. Also ToC search (<https://github.com/koreader/koreader/pull/13906>), improvements to footnote style tweaks (<https://github.com/koreader/koreader/pull/13554>). For more, please see below.

Apr 9, 2025
The [user guide](http://koreader.rocks/user_guide/) received a big update, full changelog [here](https://github.com/koreader/koreader/issues/11147#issuecomment-2751264200).
Dictionaries with images now automatically take the `res` folder as their point of departure (#12877). This means you'll have to adjust your dictionary content scripts. If you're lucky you can simply delete them.
Markdown files are now rendered differently (<https://github.com/koreader/koreader/issues/13680>).
Various changes in plugins:
- `exporter` plugin drops support for memos and flomo. You can install them from https://github.com/koreader/contrib if they work for you as is but they won't receive support here.
- `autofrontlight` plugin was removed.
- `backgroundrunner` plugin was removed. Third party plugins that rely on it to work need to be updated!
New support for KindleHF. Any Kindle running firmware ≥ 5.16.3 will need the `kindlehf` package.

Some of you on Android may have had dictionary issues. That should be fixed now.
Connecting to Wi-Fi should be more reliable on platforms where we manage it ourselves, most notably Kobo (https://github.com/koreader/lj-wpaclient/pull/11).
Color is now supported when reflowing (https://github.com/koreader/koreader/pull/12085).

A big thanks to @ezdiy and @benoit-pierre for taking on the major effort of updating MuPDF (https://github.com/koreader/koreader/pull/11940). Unfortunately or hopefully you won't notice a thing, but some edge cases in PDF rendering have been fixed.
Likewise our gratitude to @Commodore64user for the many non-touch/keyboard focused improvements.
If you used the built-in update to try out a development version in the last week of June you might need to overwrite the install manually, see https://github.com/koreader/koreader/issues/12115.

Apr 29, 2024
As usual, there have been so many changes that it's difficult to tell a coherent story about them. One of the more noticeable changes is that the sleep screen menu (formerly known as the screensaver menu) has been reworked (#11549). But there's also been a lot of work on the backend, updating the build infrastructure and crengine.

In more technical news, the CSS pseudoclasses :is(), :where() and :not() are now supported (#11353), as well as a private syntax extension for matching text in user stylesheets (#11323). Also of note is the new HttpInspector plugin, that can be used to inspect KOReader internals while it's running (#11457). This can be useful when the program is running on a device.
Last but not least, the user guide received a big update again by @offset-torque, full details [here](https://github.com/koreader/koreader/issues/11147#issuecomment-1962981373).
