![Ghost](https://github.com/user-attachments/assets/547281e0-0c6c-4910-a28b-05fc3c7923f6) 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

![koreader-202508-parasol-opt](https://github.com/user-attachments/assets/337ad26e-d400-4ce2-9a32-dd51a6edc77c) 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. This month's logo was contributed by @Sonnenfee We'd like to thank all contributors for their efforts. Some highlights since the previous release include: * [plugin] HttpInspector: fix crash when starting server (https://github.com/kore

![full-moon](https://github.com/user-attachments/assets/4f5ab8e5-7dea-407a-9916-e9ed795e0197) 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. This month's logo was contributed by @Sonnenfee We'd like to thank all contributors for their efforts. Some highlights since the previous re

![koreader-2024-11-slangie](https://github.com/user-attachments/assets/cb9e68bf-aa0f-47c7-a093-46fbf8bb19c3) **Note for Tolino users: this release freezes the system, see https://github.com/koreader/koreader/issues/12769 for more information. See https://github.com/koreader/koreader/issues/11068 for how to download a newer nightly build.** 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). This month's logo was contributed by @Sonnenfee We'd like to thank all contributors for their efforts. Some highlights since the previous release include: * Certain network features will now work in Flatpak (<https://github.com/flathub/rocks.koreader.KOReader/pull/52>) @kii-chan-reloaded * 'Use left and right keys for page turning' option added (https://github.com/koreader/koreader/pull/12174) @Commodore64user * Text editor: enhancement (https://github.com/koreader/koreader/pull/12176) @hius07 (1) Sp

![koreader-sonnenfee-2024-07-outside](https://github.com/user-attachments/assets/5c322eb2-3330-4c83-9398-6495acc60dc0) 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. This month's logo was contributed by @Sonnenfee We'd like to thank all contributors for their efforts. Some highlights since the previous release include: * SortWidget: sort alphabetically (https://github.com/koreader/koreader/pull/11705) @hius07 * bump base, docker images, and luajit-launcher: mainly compilation speedups (https://github.com/koreader/koreader/pull/11736) @benoit-pierre * ci: fix macOS build (https://github.com/koreader/koreader/pull/11660) @benoit-pierre * Multiple collections (https://github.com/

![Sonnenfee - KOReader - Theme - sourtough](https://github.com/koreader/koreader/assets/202757/08671da1-eb68-4398-aeb2-b6969d36e2c7) 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. This month's logo was contributed by @Sonnenfee We'd like to thank all contributors for their efforts. Some highlights since the previous release include: * Input: Don't let wacom pens clobber the slot of the next contact (#11520) @NiLuJe * Use Bresenham's algorithm and anti-aliasing for rounded corners (#11498) @zwim * Menu, DictQuickLookup, TextViewer: allow mousewheel scrolling (#11525) @poire-z * CoverBrowser: show cached cover of deleted file in history (#11523) @hius07 * Bookmarks: edit highlighted text (#11484) @hius07 * Fulltext search: default mode, fixes (#11507) @hius07 * ReaderFooter: chapter progress bar (#11505) @hius07 * bump crengine: better conformance to the HTML Standard rendering

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).
