Hi All,

On behalf of the NumPy team, I'm pleased to announce the release of NumPy
2.4.5. NumPy 2.4.5 is a patch release that fixes bugs discovered after the
2.4.4 release, has some typing improvements, and maintains infrastructure.

This release supports Python versions 3.11-3.14. Wheels can be downloaded
from PyPI <https://pypi.org/project/numpy/2.4.5>; release notes and the
changelog are available on Github
<https://github.com/numpy/numpy/releases/tag/v2.4.5>.
