Added a warning in :class:FacetGrid when passing a categorical plot function without specifying order (or hue_order when hue is used), which is likely to produce a plot that is incorrect.
Improved compatibility between :class:FacetGrid or :class:PairGrid and interactive matplotlib backends so that the legend no longer remains inside the figure when using legend_out=True.
Changed categorical plot functions with small plot elements to use :func:dark_palette instead of :func:light_palette when generating a sequential palette from a specified color.
Improved robustness of :func:kdeplot and :func:distplot to data with fewer than two observations.
Fixed a bug in :func:clustermap when using yticklabels=False.
Fixed a bug in :func:pointplot where colors were wrong if exactly three points were being drawn.
Fixed a bug in :func:pointplot where legend entries for missing data appeared with empty markers.
Fixed a bug in :func:clustermap where an error was raised when annotating the main heatmap and showing category colors.
Fixed a bug in :func:clustermap where row labels were not being properly rotated when they overlapped.
Fixed a bug in :func:kdeplot where the maximum limit on the density axes was not being updated when multiple densities were drawn.
Improved compatibility with future versions of pandas.
