  - The sparse output now uses the sparse matrices from the
  sparse-library. This change is motivated by the need for
  n-dimensional sparse arrays in various places. See more at the
  documentation page for sparse output.
  - The output shapes have been made more consistent across different
  descriptors: global descriptors now produce 1D flattened output and
  - local descriptors produce 2D flattened output, Whenever
  - multiple systems are given, an additional dimension is added that
  - runs across the different systems.
