# Release Status

Data Relay Link separates the **published stable release** from the mutable development `main` branch.

## Current stable

| Item                          | Current                                                          |
| ----------------------------- | ---------------------------------------------------------------- |
| Published stable release      | **v2.2.1**                                                       |
| Project version               | **2.2.1**                                                        |
| Bundled / tested relay engine | **v0.71.0**                                                      |
| Stable install source         | immutable `v2.2.1` tag                                           |
| Release commit                | `19d4b6fb8a9bee2d477ace6f5c3ed70310e7ea8f`                       |
| Release qualification         | **Two complete Real E2E passes on the same qualified candidate** |

The qualified v2.2.1 candidate and the published release tree were identical. Published v2.2.0 remains an immutable historical release.

## Stable vs development `main`

<Warning>
  `main` may contain unreleased features, fixes, or next-release preparation. A version value or feature present on `main` does **not** become a stable feature until the corresponding tag and GitHub Release are published.
</Warning>

For field installations and documentation claims, use the latest **published release/tag** as the source of truth. Do not replace the immutable stable tag with mutable `main` unless you intentionally want development-channel behavior.

This distinction is especially important when a feature has already landed on `main` but has not yet shipped in a published release.

## Install the current stable release

```bash theme={null}
curl -fsSL \
  https://raw.githubusercontent.com/xdr-labs/frp-auto-deploy/v2.2.1/dist/bootstrap-server.sh \
  | sudo bash
```

Client enrollment commands generated by the stable server should likewise remain on the stable release path.

## Data Relay Link version policy

Data Relay Link does not automatically adopt the newest upstream Data Relay Link release. The project pins an upstream version, validates it, and then ships it as part of the qualified project release.

Current bundled/tested relay engine:

```text theme={null}
0.71.0
```

`show upstream` is informational; it does not mean that a newer upstream binary is automatically supported.

## Stable platform summary

v2.2.1 has Real E2E validation for **Ubuntu 24 physical, Rocky Linux 8.10, Rocky Linux 9.4, Amazon Linux 2023, macOS Apple Silicon, and Windows 10 / PowerShell 5.1**.

Amazon Linux 2 remains **container/CI portability only**, and PowerShell 7 is **CI validated** unless a real test host actually has `pwsh` installed.

See [Supported Platforms](/reference/platforms) for the exact validation matrix and [Known Limits](/reference/limitations) for current product boundaries.
