Hi All,

On behalf of the NumPy team I am pleased to announce that NumPy 1.19.1 has
been released. This release supports Python 3.6-3.8 and may be built with
the latest Python 3.9 beta.  It 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.

Downstream developers should use Cython >= 0.29.21 when building for Python
3.9 and Cython >= 0.29.16 when building for Python 3.8. OpenBLAS >= 3.7 is
needed to avoid wrong results on the Skylake architecture. The NumPy Wheels
for this release can be downloaded from PyPI
<https://pypi.org/project/numpy/1.19.1/>, source archives, release notes,
and wheel hashes are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.19.1>. Linux users will
need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014
