Hi All,

On behalf of the NumPy team, I'm pleased to announce the release of NumPy
2.4.3. The NumPy 2.4.3 is a patch release that fixes bugs discovered after
the 2.4.2 release. The most user visible fix may be a threading fix for
OpenBLAS on ARM, closing issue #30816.

This release supports Python versions 3.11-3.14. Wheels can be downloaded
from PyPI <https://pypi.org/project/numpy/2.4.3>; release notes and the
changelog are available on Github
<https://github.com/numpy/numpy/releases/tag/v2.4.3>.
