+- Update to 3.0.2
+  * Bug fixes:
+    + Fix handling of readonly buffers in support for Pytho
+      2 legacy buffer interface. The issue triggers only when using
+      a buffer-like object that is readonly and does not export
+      the new Python 3 buffer interface.
+    + Fix build issues with Open MPI 4.0.x series related to
+      removal of many MPI-1 symbols deprecated in MPI-2 and removed
+      in MPI-3.
+    + Minor documentation fixes.
+
