API "diff" between CUDA minor versions?

CUDA releases have “Release Notes” documentation, but - that typically doesn’t cover the multitude of changes, additions and sometimes removals/deprecations from important APIs, such as the Driver, NVTX, NVRTC, PTX Compiler, etc.

Other than dirtectory-diffing the include subdirectory of two CUDA installations - is there a better way of getting the “API diff” between CUDA versions?
