CUDA-Q Releases
************************

**latest**

The latest version of CUDA-Q is on the main branch of our `GitHub repository <https://github.com/NVIDIA/cuda-quantum>`__ 
and is also available as a Docker image. More information about installing the nightly builds can be found 
:doc:`here <using/install/install>`

- `Docker image (nightly builds) <https://catalog.ngc.nvidia.com/orgs/nvidia/teams/nightly/containers/cuda-quantum>`__
- `Documentation <https://nvidia.github.io/cuda-quantum/latest>`__
- `Examples <https://github.com/NVIDIA/cuda-quantum/tree/main/docs/sphinx/examples>`__

**0.9.1**

This release adds support for using 
`Amazon Braket <https://nvidia.github.io/cuda-quantum/0.9.1/using/backends/hardware.html#amazon-braket>`__ and 
`Infeqtion's Superstaq <https://nvidia.github.io/cuda-quantum/0.9.1/using/backends/hardware.html#infleqtion>`__ as backends.

Starting with this release, all C++ quantum kernels will be processed by the `nvq++` compiler regardless of whether 
they run on a simulator or on a quantum hardware backend. This change is largely non-breaking, but language constructs 
that are not officially supported within quantum kernels will now lead to a compilation error whereas previously they 
could be used when executing on a simulator only. The previous behavior can be forced by passing the `--library-mode` 
flag to the compiler. Please note that if you do so, however, the code will never be executable outside of a simulator 
and may not be supported even on simulators.

**0.9.0**

We are very excited to share a new toolset added for modeling and manipulating the dynamics of physical systems. 
The new API allows to define and execute a time evolution under arbitrary operators. For more information, take 
a look at the `docs <https://nvidia.github.io/cuda-quantum/0.9.0/using/backends/dynamics.html>`__.
The 0.9.0 release furthermore includes a range of contribution to add new backends to CUDA-Q, including backends 
from `Anyon Technologies <https://nvidia.github.io/cuda-quantum/0.9.0/using/backends/hardware.html#anyon-technologies-anyon-computing>`__, 
`Ferimioniq <https://nvidia.github.io/cuda-quantum/0.9.0/using/backends/simulators.html#fermioniq>`__, and 
`QuEra Computing <https://nvidia.github.io/cuda-quantum/0.9.0/using/backends/hardware.html#quera-computing>`__, 
as well as updates to existing backends from `ORCA <https://nvidia.github.io/cuda-quantum/0.9.0/using/backends/hardware.html#orca-computing>`__ 
and `OQC <https://nvidia.github.io/cuda-quantum/0.9.0/using/backends/hardware.html#oqc>`__.
We hope you enjoy the new features - also check out our new notebooks and examples to dive into CUDA-Q.

The 0.8.0 release adds a range of changes to improve the ease of use and performance with CUDA-Q. 
The changes listed below highlight some of what we think will be the most useful features and changes 
to know about. While the listed changes do not capture all of the great contributions, we would like 
to extend many thanks for every contribution, in particular those from external contributors.

**0.7.1**

The 0.7.1 release adds simulator optimizations with significant performance improvements and 
extends their functionalities. The `nvidia-mgpu` backend now supports user customization of the 
gate fusion level as controlled by the `CUDAQ_MGPU_FUSE` environment variable documented 
`here <https://nvidia.github.io/cuda-quantum/0.7.1/using/backends/simulators.html>`__.
It furthermore adds a range of bug fixes and changes the Python wheel installation instructions.

**0.7.0**

The 0.7.0 release adds support for using :doc:`NVIDIA Quantum Cloud <using/backends/cloud/nvqc>`,
giving you access to our most powerful GPU-accelerated simulators even if you don't have an NVIDIA GPU.
With 0.7.0, we have furthermore greatly increased expressiveness of the Python and C++ language frontends. 
Check out our `documentation <https://nvidia.github.io/cuda-quantum/0.7.0/using/quick_start.html>`__ 
to get started with the new Python syntax support we have added, and `follow our blog <https://developer.nvidia.com/cuda-q>`__
to learn more about the new setup and its performance benefits.

**0.6.0**

The 0.6.0 release contains improved support for various HPC scenarios. We have added a
:ref:`plugin infrastructure <distributed-computing-with-mpi>` for connecting CUDA-Q 
with an existing MPI installation, and we've added a :ref:`new platform target <remote-mqpu-platform>` that distributes workloads across multiple virtual QPUs, 
each simulated by one or more GPUs.

Starting with 0.6.0, we are now also distributing 
:ref:`pre-built binaries <install-prebuilt-binaries>` for using CUDA-Q with C++.
The binaries are built against the `GNU C library <https://www.gnu.org/software/libc/>`__ 
version 2.28.
We've added a detailed :doc:`Building from Source <using/install/data_center_install>` guide to build these binaries for older `glibc` versions.
