I think rewording the summary to "scripts/get_abi.py: make it backward-compatible with Python <3.11" would resolve Jon's confusion. I haven't looked into python3'changelog, but it might be "... backward-compatible with Python <3.12". Mauro, which python3 release extended the f-string implementation? Thanks, Akira
