Release history for the Fern self-hosted Docker image. Each entry shows the `FROM` line for that release.

To upgrade:

* On `:latest` — rebuild and redeploy your image to pick up the new base.
* Pinning a version — copy the `FROM` line from the release below into your Dockerfile, then rebuild and redeploy.

See the [self-hosted setup guide](/learn/docs/self-hosted/set-up) for the full flow.
