 ## Versioning
 
-Follow [semver](https://semver.org/). Use `v` prefix for tags: `v4.0.0`, `v4.1.0-rc.1`.
+Follow [semver](https://semver.org/). Use `v` prefix for tags: `v4.0.0`, `v4.0.0-beta1`, `v4.1.0-rc.1`.
+
+Stable tags like `v4.0.0` publish to all normal distribution channels. Prerelease tags with a suffix like `-beta1`, `-beta.1`, or `-rc.1` are marked as GitHub prereleases and are not marked as the latest GitHub release.
+
+## Beta / Prerelease Releases
+
+Use a prerelease tag when technical testers need a build before the next stable version:
+
+```bash
+make release VERSION=v4.0.0-beta1
+```
+
+Prerelease behavior is intentionally conservative so existing package-manager users do not upgrade unless they explicitly opt in. Example behavior:
+
+| Surface | Stable tag `v4.0.0` | Prerelease tag `v4.0.0-beta1` |
+|---------|----------------------|--------------------------------|
+| GitHub Releases | Published as a normal release and eligible to be GitHub's latest release. | Published as a GitHub prerelease and explicitly not marked latest. |
+| Release assets | Binaries, archives, checksums, SBOMs, `.deb`, and `.rpm` artifacts are uploaded. | Same artifacts are uploaded for explicit tester download/install. |
+| curl installer | Installs `v4.0.0` once GitHub marks it latest. | Does not install the prerelease via `releases/latest`; testers must download assets explicitly. |
+| Homebrew | Updates the normal `basecamp/tap/fizzy` cask. `brew upgrade fizzy` can move users to `v4.0.0`. | Does not update the normal cask (`skip_upload: auto`). Existing `brew upgrade fizzy` users stay on the latest stable cask. |
+| Scoop | Updates the normal `fizzy` manifest. `scoop update fizzy` can move users to `v4.0.0`. | Does not update the normal manifest (`skip_upload: auto`). Existing Scoop users stay on the latest stable manifest. |
+| AUR | Updates the normal `fizzy-cli` package if `AUR_KEY` is configured. | Skips the AUR publish job. Existing AUR users stay on the latest stable package. |
+| Go install | The git tag exists for users who explicitly request it. | The prerelease tag exists for users who explicitly request it; no package-manager manifest is updated. |
+
+Technical testers can install prereleases explicitly from the GitHub release assets, for example by downloading the asset for their OS/architecture from `https://github.com/basecamp/fizzy-cli/releases/tag/v4.0.0-beta1`.
