   - Changed the visual appearance of :func:`boxenplot` to more closely resemble :func:`boxplot`. Notably, thin boxes will remain visible when the edges are white.

   - Added public access to the legend object through the ``legend`` attribute (also affects :class:`FacetGrid`).
   - The ``color`` and ``label`` parameters are no longer passed to the plotting functions when ``hue`` is not used.
   - The data is no longer converted to a numpy object before plotting on the marginal axes.
   - It is possible to specify only one of ``x_vars`` or ``y_vars``, using all variables for the unspecified dimension.
+  - The ``layout_pad`` parameter is stored and used every time you call the :meth:`PairGrid.tight_layout` method.
 
 - |Feature| Added a ``tight_layout`` method to :class:`FacetGrid` and :class:`PairGrid`, which runs the :func:`matplotlib.pyplot.tight_layout` algorithm without interference from the external legend (:pr:`2073`).

-- |Defaults| Changed the default value for ``dropna`` to ``False`` in :class:`FacetGrid`, :class:`PairGrid`, :class`JointGrid`, and corresponding functions. As all or nearly all seaborn and matplotlib plotting functions handle missing data well, this option is no longer useful, but it causes problems in some edge cases. It may be deprecated in the future. (:pr:`2204`).

 Color palettes

   - Added string-based access within the :func:`color_palette` interface to :func:`dark_palette`, :func:`light_palette`, and :func:`blend_palette`. This means that anywhere you specify a palette in seaborn, a name like ``"dark:blue"`` will use :func:`dark_palette` with the input ``"blue"``.
   - Added the ``as_cmap`` parameter to :func:`color_palette` and changed internal code that uses a continuous colormap to take this route.
-  - Tweaked the :func:`light_palette` and :func:`dark_palette` functions to use an endpoint that is a very desaturated version of the input color, rather than a pure gray. This produces smoother ramps. To exactly reproduce previous plots, use :func:`blend_palette` with ".13" for dark or ".95" for light.
