Hi All,

On behalf of the NumPy team I am pleased to announce the release of NumPy
1.16.4 which contains several fixes for newly reported bugs.  The Python
versions supported in this release are 2.7 and 3.5-3.7.

Downstream developers building this release should use Cython >= 0.29.2
and, if using OpenBLAS, OpenBLAS > v0.3.7.  Wheels for this release can be
downloaded from PyPI <https://pypi.org/project/numpy/1.16.4/>, source
archives and release notes are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.16.4>.

If you are installing using pip, you may encounter a problem with older
installed versions of NumPy that pip did not delete becoming mixed with the
current version, resulting in an ``ImportError``. That problem is
particularly
common on Debian derived distributions due to a modified pip.  The fix is
to make sure all previous NumPy versions installed by pip have been
removed. See #12736 <https://github.com/numpy/numpy/issues/12736> for
discussion of the issue.
