**Swimlane Support Update for Python 3.7 End-of-Life**

The [Python Software Foundation](https://devguide.python.org/versions/) has officially ended support for Python 3.7. In line with this change, Swimlane will also phase out support for Python 3.7 starting with platform versions released after December 31, 2025 in the 10.x platform.

Beginning with version 10.18, Swimlane introduced a dual-runner environment that supports both Python 3.7 and Python 3.12. This update allows you to continue running your existing tasks on Python 3.7 while gradually transitioning them to Python 3.12.

We encourage you to review your current tasks and integrations that use Python 3.7 and begin planning your updates to ensure a smooth migration to Python 3.12. Learn More.
