How to update the Calibre-Web Ebook library server

Read the release notes first — self-hosted projects break config and schemas between versions more often than appliances do.
Docker: pull the new image tag and recreate the container (`docker compose pull && docker compose up -d`).
Package or bare metal: update through your distribution's package manager, or replace the binary from the releases page.
Back up the config and database directory first. For most projects a downgrade is not supported once the schema has migrated.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.

FAQ

How do I update the Calibre-Web Ebook library server?

See the step-by-step above. Open the NAS control panel, go to the update or system section, and install the new version. Back up important data first; NAS updates can take several minutes.

How does Firmwarely know when there's a new version?

Every night we read the manufacturer's official release page for the Calibre-Web Ebook library server and record the version, date and changelog. If anything changed, subscribers watching this device get an email.

Is this an official Calibre-Web page?

No. Firmwarely is independent. Device and brand names belong to their manufacturers; always download firmware from the official source.
