The 0.6.0 release contains improved support for various HPC scenarios. We have added a plugin infrastructure for connecting CUDA Quantum with an existing MPI installation, and we've added a new platform target that distributes workloads across multiple virtual QPUs, each simulated by one or more GPUs.

Starting with 0.6.0, we are now also distributing pre-built binaries for using CUDA Quantum with C++. The binaries are built against the GNU C library version 2.28. We've added a detailed Building from Source guide to build these binaries for older glibc versions.
