## Esquema de segurança OAuth2

A primeira mudança é que agora nós estamos declarando o esquema de segurança OAuth2 com dois escopos disponíveis, `me` e `items`.

O parâmetro `scopes` recebe um `dict` contendo cada escopo como chave e a descrição como valor:

entity. For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity. "You" (or "Your") shall mean an individual or Legal Entity exercising permissions granted by this License. "Source" form shall mean the preferred form for making modifications, including but not limited...

### Exemplos de ferramentas e estratégias de replicação

Pode haver várias abordagens para conseguir isso, e falarei mais sobre estratégias específicas nos próximos capítulos, por exemplo, ao falar sobre Docker e contêineres.

 *  New: `ConnectionSpec.isCompatible(SSLSocket)`.
 *  New: `Dispatcher.getQueuedCallCount()` and
    `Dispatcher.getRunningCallCount()`. These can be useful in diagnostics.
 *  Fix: OkHttp no longer shares timeouts between pooled connections. This was
    causing some applications to crash when connections were reused.
 *  Fix: `OkApacheClient` now allows an empty `PUT` and `POST`.

    // we're lucky enough that these do pass, it saves us from having to write
    // more excruciating tests! Hooray!
