Backwards incompatible changes:

• Unfortunately due to a major mixup the data_aspect option added in 1.12.0 was not correctly implemented and fixing it changed its behavior significantly (inverting it entirely in some cases).
• A mixup in the convention used to compute the whisker of a box-whisker plots was fixed resulting in different results going forward.
