Hi All,

On behalf of the NumPy team I am pleased to announce the release of NumPy 1.18.5. This is a short release to enable pickle protocol=5 to be used in Python3.5 and 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. Wheels for this release can be downloaded from PyPI, source archives and release notes are available from Github.
