DataStax Python driver for Apache Cassandra®

This page describes the versions of the DataStax Python driver that are compatible with DSE, HCD, Astra DB, and open-source Cassandra.

DataStax officially supports the last 12 months of releases, and DataStax recommends using the latest driver version whenever possible. Compatibility is not guaranteed for earlier versions.

New features and bug fixes are developed on the latest minor version of the driver, and users are encouraged to stay current with those minor releases. APIs are maintained stable according to semantic versioning conventions, and upgrades should be trivial.

Unless otherwise specified, version ranges include all patch versions. For example, a range of 4.0 to 4.3 includes all versions from 4.0.0 to the last 4.3.z release.
