Hi All,

On behalf of the NumPy team I am pleased to announce that NumPy 1.18.3 has
been released. This release contains various bug/regression fixes for the
1.18 series

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 <https://pypi.org/project/numpy/1.18.3>,
source archives and release notes are available from Github


Fix for the method='eigh' and method='cholesky' options in
numpy.random.multivariate_normal. Those were producing samples from the
wrong distribution.


A total of 6 people contributed to this release.  People with a "+" by their
