This is the release note of v11.6.0. See [here](https://github.com/cupy/cupy/pulls?q=is%3Apr+is%3Aclosed+milestone%3Av11.6.0) for the complete list of solved issues and merged PRs.

**This is the last planned release for CuPy v11 series. Please start testing your workload with the v12 release candidate to get ready for the final v12 release. To install:`pip install -U --pre cupy-cuda11x -f https://pip.cupy.dev/pre`. See the [Upgrade Guide](https://docs.cupy.dev/en/latest/upgrade.html#cupy-v12) for the list of possible breaking changes in v12.**

Highlights

Wheels for CUDA 11.5 (`cupy-cuda115`) are now available.

Removal of Alpha/Beta/RC Wheels from PyPI

* As per the discussion in 5671, we stopped uploading pre-release binary wheels to PyPI for the health of the ecosystem. Pre-release wheels can now be downloaded from the recently introduced custom index (e.g., `pip install cupy-cudaXXX -f https://pip.cupy.dev/pre`) . Note that the [sdist package](https://pypi.org/project/cupy/) is available in PyPI for all versions.

* Outdated (v8.0.0rc1 or earlier) pre-release binaries have been removed from PyPI. See 5667 for details.
