NumPy 1.18.5 Release Notes#

This is a short release to allow pickle protocol=5 to be used in Python3.5. It is motivated by the recent backport of pickle5 to Python3.5.

The Python versions supported in this release are 3.5-3.8. Downstream developers should use Cython >= 0.29.15 for Python 3.8 support and OpenBLAS >= 3.7 to avoid errors on the Skylake architecture.
