Runtime & Driver API differences 11.5 -> 11.6?

Actually, a more general question:

When reading the CUDA Programming Guide, you are told what the significant changes are from the last version. But - that’s not the case for the Runtime API and Driver API parts of the documentation. What’s an effective way of finding the “diff” between subsequent version? I don’t want to resort to textual methods…

More specifically: What changes are there in the runtime and driver APIs between CUDA 11.5 and 11.6?

The release notes are also a change resource. I don’t know that it happens every time, but its fairly common to have a “whats new” blog that accompanies a CUDA toolkit release. In addition, the docs have a “send feedback” link in the upper right corner.

I don’t have other ideas or direct responses to your question.
