NumPy 1.23.4 Release Notes#

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.

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