libcu++ 1.7.0 (CUDA Toolkit 11.6)

libcu++ 1.7.0 is a major release. It adds cuda::std::atomic_ref for integral
types. cuda::std::atomic_ref may potentially replace uses of CUDA specific
atomicOperator(_Scope) calls and provides a singular API for host and device code.

Supported ABI Versions: 4 (default), 3, and 2.

New Features

• #203 Implements cuda::std::atomic_ref for integral types.
