    Hi All,

    On behalf of the NumPy team, I'm pleased to announce the release of
    NumPy 2.3.1. The NumPy 2.3.1 release is a patch release with several bug
    fixes, annotation improvements, and better support for OpenBSD. Highlights
    are:

    - Fix bug in ``matmul`` for non-contiguous out kwarg parameter
    - Fix for Accelerate runtime warnings on M4 hardware
    - Fix new in NumPy 2.3.0 ``np.vectorize`` casting errors
    - Improved support of cpu features for FreeBSD and OpenBSD

    This release supports Python 3.11-3.13, Python 3.14 will be supported when
    it is released. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/2.3.1>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v2.3.1>.
