To my knowledge, the improved support means that it is now possible to
mix CUDA and C++ code in the same source files. That is, you can
compile C++ code with a CUDA compiler, which will pass on the C++ bits
to the regular C++ compiler while extracting the CUDA code. This is
merely a technical improvement of the make system that makes it easier
to write one version code that can run on both a CPU or a GPU, instead
of having to write two separate versions of the code.

The real CUDA-related work happened in CarpetX
<https://bitbucket.org/eschnett/cactusamrex/>, which is not part of
the Einstein Toolkit yet. But we're getting there!
