Amongst other things, the next batch includes support for several new
OMP_CLAUSE_* and GOMP_MAP_* to support "private", "firstprivate",
"defaultmap", "use_device_ptr", "is_device_ptr" clauses for OpenMP
"target", "link" clause for OpenMP "declare target", C++ "this" allowed
in OpenMP "declare simd", refcount changes in libgomp,
GOMP_OFFLOAD_dev2dev (same-device memcpy).

I have not yet assessed to which extent it's possible to merge these
with/use these instead of what we had implemented on gomp-4_0-branch
already, to support related OpenACC functionality.
