This is the release note of v7.0.0b3. See here for the complete list of solved issues and merged PRs.


cupy.RawModule has been introduced to allow users access low-level features (CUDA modules).

Dropping Support of Python 2

Due to the end-of-life (EOL) of Python 2 in January 2020, Python 2 support has been dropped in this release. CuPy v6.x continues to support Python 2. See the blog post for details.
