 NumPy 2.3.1 Release Notes
 =========================
 
-The NumPy 2.3.1 release is a patch release fixes bug found after the 2.3.0
-release.
+The NumPy 2.3.1 release is a patch release with several bug fixes, annotation
+improvements, and better support for OpenBSD. Highlights are:
 
-Users running on a Mac having an M4 cpu might see various warnings about
-invalid values and such. The warnings are a known problem with Accelerate.
-They are annoying, but otherwise harmless. Apple promises to fix them.
+- 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 versions 3.11-3.13, Python 3.14 will be supported
 when it is released.
