NumPy 1.22.4 Release Notes#

NumPy 1.22.4 is a maintenance release that fixes bugs discovered after the 1.22.3 release. In addition, the wheels for this release are built using the recently released Cython 0.29.30, which should fix the reported problems with debugging.

The Python versions supported for this release are 3.8-3.10. Note that the Mac wheels are based on OS X 10.15 rather than 10.9 that was used in previous NumPy release cycles.
