Note here that your binaries will continue to run even on future driver versions - and future hardware - that's what PTX is for, as the standard libraries are statically linked in.

It's just your object files that aren't compatible, so that you can't mix and match libraries built with different CUDA versions into the same binary.

Yep, this is a good summary (good enough that perhaps I should put something similar in the docs).
