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).
