How to update the NLnet Labs Unbound resolver

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 NLnet Labs Unbound resolver?

See the step-by-step above. Log in to the router's admin page (usually at 192.168.1.1 or via the manufacturer's app), open the firmware or system update section, and apply the update. Most routers reboot for a minute or two.

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

Every night we read the manufacturer's official release page for the NLnet Labs Unbound resolver and record the version, date and changelog. If anything changed, subscribers watching this device get an email.

Is this an official NLnet Labs page?

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