  features and resolve bugs, this may change the exceptions raised from various
  methods. (#4799)

## 0.17.0

### Notable Implementation Changes

- Default to use Stackdriver Trace V2 API if calling `from google.cloud import trace`.
  Using V1 API needs to be explicitly specified in the import.(#4437)
