# Releases

Coder releases are cut directly from main in our
[Github](https://github.com/coder/coder) on the first Tuesday of each month.

We recommend enterprise customers test the compatibility of new releases with
their infrastructure on a staging environment before upgrading a production
deployment.

We support two release channels:
[mainline](https://github.com/coder/coder/releases/tag/v2.13.0) for the bleeding
edge version of Coder and
[stable](https://github.com/coder/coder/releases/latest) for those with lower
tolerance for fault. We field our mainline releases publicly for one month
before promoting them to stable.

### Mainline releases

- Intended for customers with a staging environment
- Gives earliest access to new features
- May include minor bugs
- All bugfixes and security patches are supported

### Stable releases

- Safest upgrade/installation path
- May not include the latest features
- Security vulnerabilities and major bugfixes are supported

> Note: We support major security vulnerabilities (CVEs) for the past three
> versions of Coder.

## Installing stable

When installing Coder, we generally advise specifying the desired version from
our Github [releases page](https://github.com/coder/coder/releases).

You can also use our `install.sh` script with the `stable` flag to install the
latest stable release:

```shell
curl -fsSL https://coder.com/install.sh | sh -s -- --stable
```

Best practices for installing Coder can be found on our [install](./index.md)
pages.

> **Tip**: We publish a
> [`preview`](https://github.com/coder/coder/pkgs/container/coder-preview) image
> `ghcr.io/coder/coder-preview` on each commit to the `main` branch. This can be
> used to test under-development features and bug fixes that have not yet been
> released to [`mainline`](#mainline-releases) or [`stable`](#stable-releases).
>
> > **Important**: The `preview` image is not intended for production use.
