+Increase to minimum supported versions of dependencies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For Maptlotlib 3.5, the :ref:`minimum supported versions <dependencies>` are
+being bumped:
+
++------------+-----------------+---------------+
+| Dependency |  min in mpl3.4  | min in mpl3.5 |
++============+=================+===============+
+|   NumPy    |      1.16       |     1.17      |
++------------+-----------------+---------------+
+
+This is consistent with our :ref:`min_deps_policy` and `NEP29
+<https://numpy.org/neps/nep-0029-deprecation_policy.html>`__
