Hi blair.walker,
The date is provided with Part 3 of the tutorial.
So far, I can see it will work up to S22.
R23 expects Python3 scripts.
As someone mentioned here previously, a Python2 script might be able to be updated online to Python3. I tried this, and it works with R23.
However, I’m not the developer, nor do I try to cover here Python. I leave that to the Developers and their forum. Perhaps you try it.
The four scripts work fine. Only the Pickwalker.pyp file needs to be updated.
All the best
