 NumPy 1.18.3 Release Notes
 ==========================
 
+This release contains various bug/regression fixes.
+
+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.
+
 
 Highlights
 ==========
 
+* Fix for the `method='eigh'` and `method='cholesky'` methods in
+  `numpy.random.multivariate_normal`. Those were producing samples from the
+  wrong distribution.
