Why is CPAI Python version so old?

My CodeProject.AI is apparently using an old python version (

C:\Program Files\CodeProject\AI\runtimes\bin\windows\python37

), while I also have

Python 3.11.8

installed in windows. How can I, or should I, get CodeProject.AI to use a current Python version?

What I have tried:

I'm using CPAI with:
Blue Iris 5.8.5.8 (2024-02-02)

I'm seeing errors like this in CodeProject.AI server logs:

Also note that CPAI has both python37 and python39 directories under

C:\Program Files\CodeProject\AI\runtimes\bin\windows\

, but at startup CPAI uses python37
