Log Message:
v0.8.1:

Added a warning in 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 FacetGrid or 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 dark_palette \ 
instead of light_palette when generating a sequential palette from a specified \ 
color.

Improved robustness of kdeplot and distplot to data with fewer than two observations.

Fixed a bug in clustermap when using yticklabels=False.

Fixed a bug in pointplot where colors were wrong if exactly three points were \ 
being drawn.

Fixed a bug inpointplot where legend entries for missing data appeared with \ 
empty markers.

Fixed a bug in clustermap where an error was raised when annotating the main \ 
heatmap and showing category colors.

Fixed a bug in clustermap where row labels were not being properly rotated when \ 
they overlapped.

Fixed a bug in 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.
