Unfortunately the Orient bone shapes add-on either downloaded from GitHub or from developer.blender.org does not work anymore for whatever reason.
I have tried to install those scripts on Blender 2.90.0 and 2.93.1,
namely orient_custom_shape_V2.py and orient_custom_shape.py. But unfortunately all the script gives me same error
"Upgrade to 2.8x required".
For now I manually orient the object's origin as per the bone axis and then reshape the custom shape. But it takes a lot of time...
Q: What can I do in order to get the add-on work again?
