About Calibre-Web
A yearly release cadence spent almost entirely on Kobo sync and self-hosting hardening.
Calibre-Web is a self-hosted web frontend for an existing Calibre ebook library. It ships roughly one consolidated release a year, each a large bundle in which a short new-feature list sits on top of a much longer set of bug and security fixes. The most recent releases added MOBI and audio metadata extraction on upload, reverse-proxy login via a shared secret header, multi-book editing, and Calibre 9 compatibility. Kobo e-reader sync absorbs a disproportionate share of every release.
