✨ Highlights

Updated NVIDIA [CCCL](https://github.com/nvidia/cccl)

The CCCL library bundled with CuPy has been updated to eliminate the Jitify preprocess phase. Users will no longer see the one-time performance warning (`Jitify is performing a one-time only warm-up to populate the persistent cache, this may take a few seconds and will be improved in a future release...`) unless explicitly requesting the use of Jitify (e.g., `cupy.RawModule(..., jitify=True)`).

Enhanced NumPy 2.0 Compatibility

This release provides better interoperability with NumPy 2.0.

This is the release note of v13.2.0. See [here](https://github.com/cupy/cupy/pulls?q=is%3Apr+is%3Aclosed+milestone%3Av13.2.0) for the complete list of solved issues and merged PRs.

✨ Highlights

Support for NumPy 2.0 (8357)
CuPy can now be imported under NumPy 2.0.

Lazily preloading NCCL (8367)
CuPy now loads NCCL shared library at the time of `import cupy.cuda.nccl`, instead of `import cupy`. This improves NCCL compatibility on mixed-library environments.
