This appears to be an issue on Python 3.12 for the pypandoc library which aider uses. There's a patch in pypandoc where they fix this but it isn't released yet. aider's requirements.txt is currently set to use pypandoc==1.13 which still has the syntax warning. I think Aider will need to do something like pypandoc>=1.14 once pypandoc releases to get rid of that warning.
