For advanced use cases, authentik now supports setting listening settings to a comma-separated list of IPs. With this change, the default IP we listen on changed from 0.0.0.0 to [::] to better match ecosystem standards. Some IPv4-only environments might need to adapt those settings.
This release does not introduce any new requirements. You can follow the upgrade instructions below; for more detailed information about upgrading authentik, refer to our Upgrade documentation.
:::warning When you upgrade, be aware that the version of the authentik instance and of any outposts must be the same. We recommended that you always upgrade any outposts at the same time you upgrade your authentik instance. :::
To upgrade, download the new docker-compose file and update the Docker stack with the new version, using these commands:
wget -O docker-compose.yml https://goauthentik.io/version/2026.5/lifecycle/container/compose.yml
docker compose up -d
The -O flag retains the downloaded file's name, overwriting any existing local file with the same name.
Upgrade the Helm Chart to the new version, using the following commands:
helm repo update
helm upgrade authentik authentik/authentik -f values.yaml --version ^2026.5
