## [4.0.0](https://www.github.com/googleapis/node-gtoken/compare/v3.0.2...v4.0.0) (2019-07-09)


### ⚠ BREAKING CHANGES

* This commit creates multiple breaking changes. The `getToken()`
method previously returned `Promise<string>`, where the string was the
`access_token` returned from the response.  However, the `oauth2` endpoint could
return a variety of other fields, such as an `id_token` in special cases.

```js
const token = await getToken();
// old response: 'some.access.token'
// new response: { access_token: 'some.access.token'}
```

To further support this change, the `GoogleToken` class no longer exposes
a `token` variable.  It now exposes `rawToken`, `accessToken`, and `idToken`
fields which can be used to access the relevant values returned in the
response.

### Bug Fixes

* expose all fields from response ([#218](https://www.github.com/googleapis/node-gtoken/issues/218)) ([d463370](https://www.github.com/googleapis/node-gtoken/commit/d463370))
