# Appliance Releases

> Version history for the Fish Audio enterprise appliance

Every version of the [enterprise appliance](/developer-guide/self-hosting/enterprise-appliance)
we have released, newest first. Developer → Self Host shows which one your team recorded as
running and links here when a newer one is available.

<Note>
  Versions are immutable. A tag always refers to the same image — we never
  re-point one at different content, so a deployment pinned to a tag keeps
  getting the bytes it was tested with. Fixes ship as a new version.
</Note>

## How to read a version

```
s2.1-pro-20260803-offline
└──┬───┘ └──┬───┘ └──┬──┘
   │        │        └─ variant: `offline` records usage to a local signed ledger
   │        └─ the date we published it
   └─ the model generation it serves
```

## s2.1-pro-20260803-offline

<Update label="2026-08-03" tags={["current"]}>
  First generally available build of the appliance.

  * Serves the S2.1 Pro voice model, weights baked in — no network access at runtime.
  * Two GPUs: language model on GPU 0, vocoder on GPU 1.
  * Usage recorded to a local signed ledger; nothing is reported off the host.
  * Runs fully non-root (UID 1000).

  **Upgrading:** nothing to migrate — this is the first release.
</Update>

## Getting an older version

The dashboard lists the versions we currently recommend. If you need one that is no longer
listed — to reproduce a node exactly as it was, for instance — contact your account manager
rather than guessing a tag.
