# Releases

> How Fish Audio Enterprise versions are identified and how to move between them

Fish Audio publishes a version of each delivery form once it has been tested.
**Developer → Self Host** lists the versions available to your team and fills the
one you pick into the install commands on that page.

## Version identifiers

| Delivery form                | Identified by   | Applied with                         |
| ---------------------------- | --------------- | ------------------------------------ |
| Online Helm and Offline Helm | A chart version | `--version` on `helm pull`/`install` |
| All-in-One                   | An image tag    | The tag in the image reference       |

Both Helm forms are one chart, so they share a version. Which form you deploy is
decided by the values file, not by the version.

## Upgrading

A deployment stays on its version until you change it. Take the new version from
**Developer → Self Host**, then follow
[Upgrade](/developer-guide/self-hosting/kubernetes#upgrade) for the Helm forms,
or pull the new tag and recreate the container against the same volume for
[All-in-One](/developer-guide/self-hosting/all-in-one). Air-gapped deployments
mirror the new version first — see
[Air-gapped deployments](/developer-guide/self-hosting/air-gapped).

<Note>
  Talk to your account team before skipping versions, and before upgrading a
  production deployment, so the change can be checked against how yours is
  configured.
</Note>

## Next step

Return to [Kubernetes deployment](/developer-guide/self-hosting/kubernetes) or
[All-in-One container](/developer-guide/self-hosting/all-in-one) to apply the
version you picked.
