NumPy 1.19.1 Release Notes

NumPy 1.19.1 fixes several bugs found in the 1.19.0 release, replaces
several functions deprecated in the upcoming Python-3.9 release, has
improved support for AIX, and has a number of development related
updates to keep CI working with recent upstream changes.

This release supports Python 3.6-3.8. Cython >= 0.29.21 needs to be
