v0.2.1 (December 2013)

This is a bugfix release, with no new features.

Bug fixes

• Changed the mechanics of violinplot() and boxplot() when using a Series object as data and performing a groupby to assign data to bins to address a problem that arises in Pandas 0.13.

• Additionally fixed the groupby code to work with all styles of group specification (specifically, using a dictionary or a function now works).

• Fixed a bug where artifacts from the kde fitting could undershoot and create a plot where the density axis starts below 0.

• Ensured that data used for kde fitting is double-typed to avoid a low-level statsmodels error.

• Changed the implementation of the histogram bin-width reference rule to take a ceiling of the estimated number of bins.
