Hi All,

On behalf of the NumPy team, I'm pleased to announce the release of NumPy 1.26.3. NumPy 1.26.3 is a maintenance release that fixes bugs and regressions discovered after the 1.26.2 release. The most notable fixes are the f2py bug fixes. The Python versions supported by this release are 3.9-3.12. Wheels can be downloaded from PyPI; source archives, release notes, and wheel hashes are available on Github.
