Installation

This is a hot-fix release for [v7.1.0](https://github.com/cupy/cupy/releases/tag/v7.1.0) to address an issue in CUB support. Only users manually building CuPy from source with CUB support enabled are affected; wheel package users (`cupy-cudaXXX`) are not affected by this issue as CUB support is not enabled in wheels.

This is the release note of v7.1.1. See [here](https://github.com/cupy/cupy/milestone/67?closed=1) for the complete list of solved issues and merged PRs.

Bug Fixes

- Fix import of `_get_axis` in `cupy.cub` (2986, thanks jakirkham!)
