| # Changelog | ||
|
|
||
| ## v0.28.0 | ||
|
|
||
| **v0.28.0 significantly changes the interface for this package.** For examples | ||
| of the differences between v0.28.0 and previous versions, see [Migrating to | ||
| the BigQuery Python client library | ||
| v0.28](https://cloud.google.com/bigquery/docs/python-client-migration). | ||
| These changes can be summarized as follows: | ||
|
|
||
| - Query and view operations default to the standard SQL dialect. (#4192) | ||
| - Client functions related to | ||
| [jobs](https://cloud.google.com/bigquery/docs/jobs-overview), like running | ||
| queries, immediately start the job. | ||
| - Functions to create, get, update, delete datasets and tables moved to the | ||
| client class. | ||
|
|
||

|
||
| PyPI: https://pypi.org/project/google-cloud-bigquery/0.27.0/ | ||
|
|
||
| ## 0.26.0 | ||
|
|
||
| ### Notable implementation changes | ||
|
|
||
| - Using the `requests` transport attached to a Client for for resumable media | ||
| (i.e. downloads and uploads) (#3705) (this relates to the `httplib2` to | ||
| `requests` switch) | ||
|
|
||
| ### Interface changes / additions | ||
|
|
||
| - Adding `autodetect` property on `LoadTableFromStorageJob` to enable schema | ||
| 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) | ||
