# CUDA Python 12.3.0 Release notes

Released on October 19, 2023

## Highlights
- Rebase to CUDA Toolkit 12.3
- Resolve [Issue #16](https://github.com/NVIDIA/cuda-python/issues/16): cuda.cudart.cudaRuntimeGetVersion() hard-codes the runtime version, rather than querying the runtime
    - New API cudart.getLocalRuntimeVersion()
- Resolve [Issue #48](https://github.com/NVIDIA/cuda-python/issues/48): Dropping Python 3.8
- Resolve [Issue #51](https://github.com/NVIDIA/cuda-python/issues/51): Dropping package releases for ppc64 on PYPI and conda-nvidia channel
