Google Cloud PHP v0.23.0

Google Cloud PHP v0.23.0

Cloud Pub/Sub

• ❗ BREAKING CHANGE The return type of
  Google\Cloud\PubSub\Subscription::pull() has changed from
  Generator<Google\Cloud\PubSub\Message> to Google\Cloud\PubSub\Message[].
  (#375)

Cloud Vision

• Cloud Vision in Google Cloud PHP is now considered beta! That means that while
  we're not quite ready to call it done, we're getting a lot closer. You should
  expect more stability and fewer breaking changes between now and our 1.0
  release. (#387)

Various and Sundry

• Fixed a bug where application identifying headers were not sent when using an
  API key rather than a service account over the REST transport. (#378)
