✨ Highlights

This is a hot-fix release for [v12.1.0](https://github.com/cupy/cupy/releases/tag/v12.1.0) to address an issue reported in #7593 that `pip install cupy-wheel` raises an error with Pip v23.1 or later. See [here](https://github.com/cupy/cupy/pulls?q=is%3Apr+is%3Aclosed+milestone%3Av12.1.0.post1) for the complete list of solved issues and merged PRs.

This fix only applies to the [`cupy-wheel`](https://pypi.org/project/cupy-wheel/13.0.0a1/) meta package. As there are no differences in CuPy functionalities with v12.1.0, no releases are made for CuPy's source/binary packages.

We are also considering removing `cupy-wheel` meta package in CuPy v13. Join the discussion in 7628 if you have any suggestions or comments.

Highlights

Support for CUDA 12.1 & cuDNN 8.8 (7484 & 7475)

CuPy now supports CUDA 12.1 and cuDNN 8.8. Binary packages are available for Linux (x86_64/aarch64) and Windows as `cupy-cuda12x`.


$ pip install cupy-cuda12x


Announcements

Arm packages available in PyPI

Binary packages for aarch64 (Jetson and Arm servers) can now be installed from PyPI.


$ pip install cupy-cuda102
$ pip install cupy-cuda11x
$ pip install cupy-cuda12x


~Note: At the time of the release, Arm wheel of `cupy-cuda11x` for Python 3.8 (`cupy_cuda11x-12.0.0-cp38-cp38-manylinux2014_aarch64.whl`) is not available on PyPI. We are working on resolving this issue. Meanwhile, this wheel can be installed from the CuPy index. `$ pip install cupy-cuda11x -f https://pip.cupy.dev/aarch64`~ This issue was resolved on 2023-04-03.
