If data types and order still match, the parameter may have been renamed rather than actually having a significant change to the function signature.

Add the files needed to make so we can install this git repo using pip.

Searching for differences should make sure that for added functions it outputs the return type. Return type should also be a factor that is considered when determining if a function has changed (if it isn't already).

libclang is returning a type of "int" (or "Int" depending on the function/attribute used), instead of what it had been returning before -- "int32_t" or "int64_t". It is also adding typedefs for each enum, which wasn't happening before.

This may be a macOS specific bug with libclang (the Python bindings?); a Google search turned up a similar issue with Ubuntu where size_t was getting reported by libclang as being of type int.

Note: running clang -Xclang --ast-dump=json -fsyntax-only <header_file> prints the expected type names, but is extremely verbose and includes information on included header files (C/C++ standard library)... it may be worth looking into alternatives to libclang, maybe some that are a bit more user friendly. Python options are likely the easiest/most direct to port, but other languages would also be fine if the available library is easy enough to use (whatever underpins rust bindgen and similar tooling).
