I have a CAA development question.

Starting with V5-6R2021 I get the following compile errors. My V5-6R2020 solution compiles without any issues. This tells me there have been possible compiler requirement changes. The new solution was created using the 2020 solution settings. I just fix any specific paths to pickup the 2021 includes, libs etc.

Has anyone seens this? Is there a CAA area where this is better posted?
