   - 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
