It's been about four months since the previous release, so it's about time, isn't it? One very interesting addition is background cleanup for PDFs with Mask and SMask, which is technobabble for backgrounds (particularly in Archive.org PDFs, ). It means you might not need preprocessing to be able to open them on your ereader without having to be fairly patient when turning pages, though the usual warnings apply: backgrounds are not *just* the yellowish color of paper, but they might also contain most of the non-textual content, if any.
Kobo v5 support was finally merged (), and will also reach the nightly builds server soon. There's also new or improved support for the PocketBook Era Lite, reMarkable Paper Pure, newer Onyx Android devices, and some Kindle models.
The hotkeys plugin now supports single-key shortcuts (https://github.com/koreader/koreader/pull/14867), and speaking of plugins, there is now built-in support to delete them (https://github.com/koreader/koreader/pull/15240).
SyncService is replaced by the new Cloud storage plugin (https://github.com/koreader/koreader/pull/15210). It supports uploading, downloading, and deleting selected files, configurable servers and upload folders, natural sorting, and improved WebDAV handling.
And last but not least, there's now OPDS 2.0 basic support (https://github.com/koreader/koreader/pull/15696).

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 (https://github.com/koreader/koreader/pull/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.
