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 latest 12 months of releases, and DataStax recommends using the latest driver version whenever possible. Compatibility isn’t 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.

Python driver ownership and other important changes in version 3.30
Starting with versions 3.30, the Python driver is maintained by the Apache Software Foundation (ASF). Prior versions were maintained by DataStax.
As of version 3.30, there is no change to the Python driver package name.
You can still install the driver with pip install cassandra-driver.
However, there are important changes in version 3.30 that you should be aware of, including use of pyproject.toml, the DRIVER_NAME in STARTUP messages, and the supported Python versions.
For more information, see the Python driver upgrade guide.
