NumPy 1.16.5 Release Notes#

The NumPy 1.16.5 release fixes bugs reported against the 1.16.4 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 v0.3.7-dev, which should fix errors on Skylake series cpus.

Downstream developers building this release should use Cython >= 0.29.2 and, if using OpenBLAS, OpenBLAS >= v0.3.7. The supported Python versions are 2.7 and 3.5-3.7.
