## Documentation content

> [!WARNING] Deprecation notice
> Python 3.13 has now replaced 3.11 as the default notebook and codespace environment.

New notebooks and codespaces now use the built-in Python 3.13 environment image by default, replacing Python 3.11. The image includes Python 3.13, the DataRobot Python client, and common data science libraries. It is also required to [connect a local IDE to a codespace](https://docs.datarobot.com/en/docs/workbench/notebook/codespaces/connect-local.html.md) over SSH.

Existing notebooks and codespaces keep the image already selected for them. To continue using Python 3.11, choose that image on the Environment tab. Self-managed administrators can restore Python 3.11 as the cluster default by setting `DEFAULT_ENV_ID` in `values.yaml`; see [Notebooks](https://docs.datarobot.com/en/docs/api/reference/public-api/notebooks.html.md#v1113).

Python 3.11 will be deprecated in a future release. DataRobot recommends upgrading to Python 3.13.
