 NumPy 1.19.5 Release Notes
 ==========================
 
+NumPy 1.19.5 is a short bugfix release. Apart from fixing several bugs, the
+main improvement is the update to OpenBLAS 0.3.13 that works around the windows
+2004 bug while not breaking execution on other platforms. This release supports
+Python 3.6-3.9 and is planned to be the last release in the 1.19.x cycle.
