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.
