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, source archives and release notes are available from Github.

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 for discussion of the issue.
