 - Add :class:`pandas_gbq.Context` to cache credentials in-memory, across
   calls to ``read_gbq`` and ``to_gbq``. (:issue:`198`, :issue:`208`)
+- Fast queries now do not log above ``DEBUG`` level. (:issue:`204`).
+  With BigQuery's release of `clustering <https://cloud.google.com/bigquery/docs/clustered-tables>`__
+  querying smaller samples of data is now faster and cheaper.
