+Increase to minimum supported versions of dependencies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For Matplotlib 3.9, the :ref:`minimum supported versions <dependencies>` are
+being bumped:

++------------+-----------------+---------------+
+| Dependency |  min in mpl3.8  | min in mpl3.9 |
++============+=================+===============+
+|   NumPy    |       1.21.0    |      1.22.0   |
++------------+-----------------+---------------+
+
+This is consistent with our :ref:`min_deps_policy` and `NEP29
