KOReader 2026.03 “Snowflake”
As one of the maintainers of KOReader, a versatile a document and image viewer, I’m proud to announce the latest release.
There’s a pretty big update on desktop this time around. We’ve upgraded from SDL2 to SDL3 (#14983). This should mean everything works the same or better, but let us know if we missed some edge case. For the nearby future it does have the side effect of always shipping along SDL3, even in the DEB packages, because only recent distros provide it out of the box.
There are many other improvements, like stable pages in file browser (#14570). I won’t bore you with more nonsense (read: there were some holdups with the release and my mental overview was lost), and I’ll just let the PRs speak for themselves.
This month’s logo was contributed by @Sonnenfee
