# Stable support

> Support boundaries and incident reporting for the Sifr stable channel.

## Supported release surface

Stable support covers active governed releases installed from
`https://sifr.sh/install` on the four targets listed in
[stable compatibility](/releases/compatibility). Support applies to the exact
compiler, sysroot, installer, and VS Code compatibility metadata published for
that release.

Alpha and beta remain preview channels. `rc` is not a public channel. Windows
standalone installers and package-manager distribution are outside the current
support boundary.

## Before reporting a problem

Collect the following details:

```bash theme={null}
sifr --version
sifr self version --format json
```

Include your operating system, architecture, the failing command, and the
complete diagnostic. For editor problems, include VS Code extension version
`0.2.0`, the configured `sifr.lsp.path`, and the Sifr language-server output.

Do not include credentials, private source code, or access tokens.

## Release incidents

The release team can withdraw a bad stable version. Withdrawal immediately
blocks fresh installs and exact pins while preserving immutable release and
incident evidence. Existing users receive a governed rollback or
incident-roll-forward instruction; Sifr never silently installs an
unapproved version.

For installation and update recovery, follow
[stable troubleshooting](/troubleshooting).
