- Kubectl [get and describe](https://github.com/kubernetes/enhancements/issues/515) now works with extensions
- Nodes now support [third party monitoring plugins](https://github.com/kubernetes/enhancements/issues/606).

O parâmetro `name` **ainda é obrigatório** (não *opcional*) porque ele não possui um valor padrão. Mesmo assim, `name` aceita `None` como valor:

```Python
say_hi(name=None)  # This works, None is valid 🎉
```

A boa notícia é, quando você estiver no Python 3.10 você não precisará se preocupar mais com isso, pois você poderá simplesmente utilizar o `|` para definir uniões de tipos:

#### General guidelines and philosophy for contribution

*   Include unit tests when you contribute new features, as they help to a)
    prove that your code works correctly, and b) guard against future breaking
    changes to lower the maintenance cost.
*   Bug fixes also generally require unit tests, because the presence of bugs
    usually indicates insufficient test coverage.

 * if (forceCacheResponse.code() != 504) {
 *   // The resource was cached! Show it.
 * } else {
 *   // The resource was not cached.
 * }
 * ```
 *
 * This technique works even better in situations where a stale response is better than no response.
 * To permit stale cached responses, use the `max-stale` directive with the maximum staleness in
 * seconds:
 *
 * ```java
