Authelia v4.39.25 released on 10-09-2026
Authelia v4.39.25 is out now. It fixes an SMTP notification failure affecting IPv6 literal addresses (for example [::1]) and publishes updated container images so deployments using SMTP over IPv6 can deliver alerts correctly.
See the project’s GitHub release page for full details and pull the patched images for Docker or Kubernetes deployments.
What’s in this release
- Bug fix for SMTP notification failures when using IPv6 literal addresses (commit ffa6a89), closing issue #13041.
- Updated Docker container images published: authelia/authelia:4.39.25 and ghcr.io/authelia/authelia:4.39.25.
- Patch contributed by @james-d-elliott resolving notification delivery over IPv6 literals.
Upgrade notes
- Users running SMTP notifications with IPv6 literal addresses should upgrade and pull the new images: docker pull authelia/authelia:4.39.25 and docker pull ghcr.io/authelia/authelia:4.39.25.
- If you encounter problems after updating, roll back to your previous image tag and validate SMTP delivery before re-enabling alerts.
