KOReader 2019.04

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

March mainly brought various under the hood improvements like faster blitting and better line-height handling, but also a more visible dual pages display toggle. On supported platforms, most two-finger swipes are now also configurable in the gesture manager.

GUN Tar

A while back a typo evaded me. GNU Tar is a utility originally conceived for writing (t)ape (ar)chives, a type of backup, whereas GUN Tar presumably doesn’t exist. Even if it did, it wouldn’t have anything to do with the GNU part of the equation.

Curious about the prevalence of this typo, I quickly found some unrelated but very interesting pictures. A guntar is a a combination of a gun and a guitar — obviously. 😉

Btw, there’s a picture of a guntar here (via)

a guntar, a guitar with a hunting rifle on it

Here’s a random video of Frank Klepacki playing some songs from Red Alert on his “Vengeance” guitar. I’m not really into guitars, but they can be quite interesting visually.

The typo itself is actually surprisingly rare. I searched for "gun tar" -guns -military -shot -shoot -shooting -foam but it’s still showing a lot of noise. Only one result was about GNU Tar, namely and embarrassingly, the typo made it into a published book: Utilizing Open Source Tools for Online Teaching and Learning: Applying Linux. Adding an extract at the end, i.e., "gun tar" -guns -military -shot -shoot -shooting -foam extract greatly improves on the ratio of typo results.

KOReader 2019.03 “Marsdiep”

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


The Marsdiep is a strait between the North Sea and the Wadden Sea (Wikipedia). When high tide approaches water flows east, and when the tide lowers it flows back west. Inspired by this natural phenomenon, our March release introduces multiswipes, short for multiswipe gestures. A swipe east, directly followed by a swipe west without taking your finger off the screen, will now take you directly to your latest bookmark. All of these are fully configurable in the gesture manager, which can now be found in the new SettingsTaps and gestures menu.

Various Android E Ink ereaders were added to the list of supported devices. Please keep your feedback coming in our dedicated issue!

Android and AppImages can now check for nightly and stable updates from within the program (#4620, #4639).

Because there is so much to cover, here are a few things that stand out to me personally:

  • @Galunid added the ability to allow for adjusting highlights (#4582).
  • @poire-z fixed up an issue with ligatures and hyphenation, so that “best” font kerning is now truly best (#4593).
  • @NiLuJe added hardware dithering on supported platforms (#4541).
  • @houqp decoupled the render core & hardware from UI (#4580). This sounds a bit cryptic, but it means you can now much easier use KOReader’s backend as a Lua module to build entirely new GUI concepts on top of it.

Default multiswipes

These are simply the gestures we thought to be most useful, but they’re hardly the be all and end all. You can add your own gestures using the multiswipe recorder (#4644).

We’d like to thank all contributors for their efforts. Some highlights since the previous release include:

  • Page overlap menu (cre): set nb of overlap lines (#4538) @poire-z

KOReader 2018.11 “An die Freude”

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


Twenty-five years ago today, the Maastricht Treaty took effect. So let’s take a moment to enjoy the Anthem of Europe before moving on to regular business.

This release introduces support for BQ/Fnac devices, ported by @pazos (#4294). More information about how to turn your device into an open Linux reader can be found here. You will have to replace /etc/rc.local with the content of koreader-standalone.sh. We hope this sparse documentation will suffice for the moment, because we really wanted to include all of these devices in this release!

Going forward, the tagged releases on GitHub will be considered stable, unless otherwise indicated by a suffix such as -beta or -rc. Hopefully this will remove user confusion about which release to use, particularly since new users will often be on newer devices that require a recent version (#4292).

The many changes since the last stable release are too numerous to mention or do justice. There were many visible changes, but even more under the hood. A few that stand out to me personally include:

We’d like to thank all contributors for their efforts. Some highlights since the previous beta release include:
