## 0.28.0

**0.28.0 significantly changes the interface for this package.** For examples
of the differences between 0.28.0 and previous versions, see
[Migrating to the BigQuery Python client library 0.28][2].
These changes can be summarized as follows:

  autodetection. (#3648)
- Implementing the Python Futures interface for Jobs. Call `job.result()` to
  wait for jobs to complete instead of polling manually on the job status.
  (#3626)
- Adding `is_nullable` property on `SchemaField`. Can be used to check if a
  column is nullable. (#3620)
- `job_name` argument added to `Table.upload_from_file` for setting the job
  ID. (#3605)
- Adding `google.cloud.bigquery.dbapi` package, which implements PEP-249
  DB-API specification. (#2921)
- Adding `Table.view_use_legacy_sql` property. Can be used to create views
  with legacy or standard SQL. (#3514)

### Interface changes / breaking changes

- Removing `results()` method from the `QueryJob` class. Use
  `query_results()` instead. (#3661)
- `SchemaField` is now immutable. It is also hashable so that it can be used
  in sets. (#3601)

### Dependencies

- Updating to `google-cloud-core ~= 0.26`, in particular, the underlying HTTP
  transport switched from `httplib2` to `requests` (#3654, #3674)
- Adding dependency on `google-resumable-media` for loading BigQuery tables
  from local files. (#3555)

### Packaging

- Fix inclusion of `tests` (vs. `unit_tests`) in `MANIFEST.in` (#3552)
- Updating `author_email` in `setup.py` to `googleapis-publisher@google.com`.
  (#3598)
