 We can now commit our new feature on `beta`. When pushing that commit, **semantic-release** will publish the pre-release version `3.1.0-beta.1` on the dist-tag `@beta`. That allow us to run integration tests by installing our module with `npm install example-module@beta`. Other users installing with `npm install example-module` will still receive the version `3.0.0`.
