+Development changes
+-------------------
+
+Increase to minimum supported versions of dependencies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For Matplotlib 3.5, the :ref:`minimum supported versions <dependencies>` and
+some :ref:`optional dependencies <optional_dependencies>` are being bumped:
+
++---------------+---------------+---------------+
+| Dependency    | min in mpl3.4 | min in mpl3.5 |
++===============+===============+===============+
+| NumPy         |     1.16      |     1.17      |
++---------------+---------------+---------------+
+| Tk (optional) |     8.3       |     8.4       |
++---------------+---------------+---------------+
+
+This is consistent with our :ref:`min_deps_policy` and `NEP29
+<https://numpy.org/neps/nep-0029-deprecation_policy.html>`__
+
+New runtime dependencies
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+fontTools for type 42 subsetting
+................................
+
+A new dependency `fontTools <https://fonttools.readthedocs.io/>`_ is integrated
+into Matplotlib 3.5. It is designed to be used with PS/EPS and PDF documents;
+and handles Type 42 font subsetting.
+
+Underscore support in LaTeX
+...........................
+
+The `underscore <https://ctan.org/pkg/underscore>`_ package is now a
+requirement to improve support for underscores in LaTeX.
+
+This is consistent with our :ref:`min_deps_policy`.
+
+Matplotlib-specific build options moved from ``setup.cfg`` to ``mplsetup.cfg``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In order to avoid conflicting with the use of :file:`setup.cfg` by
+``setuptools``, the Matplotlib-specific build options have moved from
+``setup.cfg`` to ``mplsetup.cfg``
+
+Note that the path to this configuration file can still be set via the
+:envvar:`MPLSETUPCFG` environment variable, which allows one to keep using the
+same file before and after this change.
