Python runtime version selector and 3.14 availability

This feature is currently rolling out to cloud-hosted organizations and will be available in an upcoming self-hosted release.

You can now select the Python version used by a workflow from the Languages & Libraries tab. Click ... next to Python, select Update version, and choose between Python 3.10 and 3.14.

Python 3.14 does not include built-in libraries. When you upgrade, Retool automatically identifies any built-in libraries your workflow uses and installs them as custom libraries.
