 What you'll need:
- * [Python 3.10.15 or newer](https://www.python.org/downloads/), not the Windows Store version
+ * [Python 3.10.11 or newer](https://www.python.org/downloads/), not the Windows Store version
+   * On Windows, please consider only using the latest supported version in production environments since security
+     updates for older versions are not easily available.
    * Python 3.12.x is currently the newest supported version
  * pip: included in downloads from python.org, separate in many Linux distributions
  * Matching C compiler
