+
+    Once the PR is merged, publish a GitHub release for `#{new_version}`, targeting `trunk`,
+    with the following text as description:
+
+    ```
+    #{changelog.join}
+    ```
+
+    The publication of the new GitHub release will create a git tag, which in turn will trigger
+    a CI workflow that will take care of doing the `gem push` of the new version to RubyGems.
