Features

oLabel now honors several orient and padding settings in radial mode (pie charts). You can send oLabel={{ label: "true", orient: "stem" }} and get:

It also honors "edge" (which is the new default) so oLabel={true} will give you:

oLabel={{ label: "true", orient: "edge", padding: -10 }} insets the labels:

The old default (arc centroid) can be achieved with orient: "center" but why would you with these cool options?
legend honors an orientation="horizontal" to create simple horizontal legends.
