CuPy v7.0.0b3 をリリースしました！ リリースノートは以下の通りです。

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

Highlights

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.
