# 2.0.0 Migration Guide The 2.0 release of the google-cloud-bigquery client drops support for Python versions below 3.6. The client surface itself has not changed, but the 1.x series will not be receiving any more feature updates or bug fixes. You are thus encouraged to upgrade to the 2.x series. If you experience issues or have questions, please file an issue.

The 2.0.0 release requires BigQuery Storage >= 2.0.0, which dropped support
for v1beta1 and v1beta2 versions of the BigQuery Storage API. If you want to
use a BigQuery Storage client, it must be the one supporting the v1 API version.
