This is the release note of v10.6.0. See [here](https://github.com/cupy/cupy/pulls?q=is%3Apr+is%3Aclosed+milestone%3Av10.6.0) for the complete list of solved issues and merged PRs.

**This is the last planned release for CuPy v10 series. We are going to release v11.0.0 on July 28th. Please start testing your workload with the v11 release candidate (`pip install --pre cupy-cuda11x -f https://pip.cupy.dev/pre`). See the [Upgrade Guide](https://docs.cupy.dev/en/latest/upgrade.html#cupy-v11) for the list of possible breaking changes in v11.**

Announcements

Introduction of generic `cupy-wheel` (EXPERIMENTAL) (6012)

We have added a new package in the PyPI called `cupy-wheel`. This meta package allows other libraries to add a dependency to CuPy with the ability to transparently install the exact CuPy binary wheel matching the user environment. Users can also install CuPy using this package instead of manually specifying a CUDA/ROCm version.


pip install cupy-wheel


This package is only available for the stable release as the current pre-release wheels are not hosted in PyPI.

This feature is currently experimental and subject to change so we recommend users not to distribute packages relying on it for now. Your suggestions or comments are highly welcomed (please visit 6688.)

Changes

Enhancements
- Add missing `cudaDevAttrMemoryPoolsSupported` to hip (6626)
- Add CC 3.2 to Tegra arch list (6647)
- Add a few driver/runtime/nvrtc API wrappers (6651)

Bug Fixes
- Define `float16::operator-()` only for ROCm 5.0+ (6629)
- JIT: fix access to cached codes (6642)
- [v10] Fix Mempool attr for Cuda Python (6654)
- Fix int64 overflow in `cupy.polyval` (6666)

Documentation
- Documentation update for ROCm 5.0 (6607)
- Add `--pre` option to instructions installing pre-releases (6614)
- Fix typo in performance guide (6659)
- JIT: fix function signatures in the docs (6660)

Installation
- Add universal CuPy package (6683)

Tests
- Remove `jenkins` requirements (6634)
- CI: Trigger FlexCI for hotfix branches (6636)
- Fix `TestIncludesCompileCUDA` for HEAD tests (6650)
- Trigger CUDA Python tests with `/test mini` (6655)
- Fix missing f prefix on f-strings fix (6679)
