+==========================
+NumPy 1.17.2 Release Notes
+==========================
+
+This release contains fixes for bugs reported against NumPy 1.17.1 along with a
+some documentation improvements. The most important fix is for lexsort when the
+keys are of type (u)int8 or (u)int16. If you are currently using 1.17 you
+should upgrade.
+
+The Python versions supported in this release are 3.5-3.7, Python 2.7 has been
+dropped.  Python 3.8b4 should work with the released source packages, but there
+are no future guarantees.
+
+Downstream developers should use Cython >= 0.29.13 for Python 3.8 support and
+OpenBLAS >= 3.7 to avoid errors on the Skylake architecture. The NumPy wheels
+on PyPI are built from the OpenBLAS development branch in order to avoid those
+errors.
