Hi All,

On behalf of the NumPy team, I am pleased to announce the release of
NumPy 1.23.4. NumPy 1.23.4 is a maintenance release that fixes bugs
discovered after the 1.23.3 release and keeps the build infrastructure
current. The main improvements are fixes for some annotation corner cases,
a fix for a long time *nested_iters* memory leak, and a fix of complex
vector dot for very large arrays. The Python versions supported for this
release are 3.8-3.11. Wheels can be downloaded from PyPI
<https://pypi.org/project/numpy/1.23.4>; source archives, release notes,
and wheel hashes are available on Github

Note that the mypy version needs to be 0.981+ if you test using Python
3.10.7, otherwise the typing tests will fail.
