This version was released just before SciPy 2020 and Boost 1.74. Highlights
include better accumulator views, simpler summing, better NumPy and Pandas
compatibility, and sums on growing axes. Lots of backend work,
including a new wheel building system, internal changes and better reliance
on Boost.Histogram's C++ tools for actions like cropping.
