+The NumPy 1.16.3 release fixes bugs reported against the 1.16.2 release, and
+also backports several enhancements from master that seem appropriate for a
+release series that is the last to support Python 2.7. The wheels on PyPI are
+linked with OpenBLAS v0.3.4+,  which should fix the known threading issues
+found in previous OpenBLAS versions.
+
+Downstream developers building this release should use Cython >= 0.29.2 and,
+if using OpenBLAS, OpenBLAS > v0.3.4.
+
+The most noticeable change in this release is that unpickling object arrays
+when loading ``*.npy`` or ``*.npz`` files now requires an explicit opt-in.
+This backwards incompatible change was made in response to
+`CVE-2019-6446 <https://nvd.nist.gov/vuln/detail/CVE-2019-6446>`_.

 ``__array_interface__`` offset now works as documented
