Aqui, a função de manipulador do evento `shutdown` escreverá uma linha de texto `"Application shutdown"` no arquivo `log.txt`.

/// info | Informação

Na função `open()`, o `mode="a"` significa "acrescentar", então a linha será adicionada depois do que já estiver naquele arquivo, sem sobrescrever o conteúdo anterior.

TLS Configuration History
=========================

OkHttp tracks the dynamic TLS ecosystem to balance connectivity and security. This page is a log of
changes we've made over time to OkHttp's default TLS options.

[OkHttp 3.14][OkHttp314]
------------------------

_2019-03-14_

Remove 2 TLSv1.3 cipher suites that are neither available on OkHttp’s host platforms nor enabled in releases of Chrome and Firefox.

##### RESTRICTED_TLS cipher suites

OAuth2 with scopes is the mechanism used by many big authentication providers, like Facebook, Google, GitHub, Microsoft, X (Twitter), etc. They use it to provide specific permissions to users and applications.

Every time you "log in with" Facebook, Google, GitHub, Microsoft, X (Twitter), that application is using OAuth2 with scopes.
