 * Improved documentation for `aes()` and many geoms and scales. I've tried
   to reduce the use of `...` so that you can see all the documentation in one
   place rather than having to navigate through multiple pages.
-* Added new function geom_curve to add curved lines to plot (similar to
-  geom_segment to add straight lines). (@veraanadi)
