## Add Labels to PRs

The same GitHub Action <a href="https://github.com/tiangolo/latest-changes" class="external-link" target="_blank">latest-changes</a> uses one label in the PR to decide the section in the release notes to put this PR in.

Make sure you use a supported label from the <a href="https://github.com/tiangolo/latest-changes#using-labels" class="external-link" target="_blank">latest-changes list of labels</a>:

Agora vamos **refatorar** este app um pouco para aumentar a **segurança** e **versatilidade**.

Se você verificar o app anterior, na interface você pode ver que, até agora, ele permite que o cliente decida o `id` do `Hero` a ser criado. 😱

These are issues that we believe are particularly well suited for outside
contributions, often because we probably won't get to them right now. If you
decide to start on an issue, leave a comment so that other people know that
you're working on it. If you want to help out, but not alone, use the issue
comment thread to coordinate.

Ya creaste una API que:

* Recibe requests HTTP en los _paths_ `/` y `/items/{item_id}`.
* Ambos _paths_ toman _operaciones_ `GET` (también conocidas como métodos HTTP).
* El _path_ `/items/{item_id}` tiene un _parámetro de path_ `item_id` que debe ser un `int`.

   * <p>On the other hand, if for example we are resolving {@code List<A extends B>} to {@code
