optional output of sequence and orders by use of an optional parameter "output_sensitivities". redone the setup.py script to use pure setuptools (including a pyproject.toml)
0.9.5
Fixed underflow in calculation of the distance field tau0 (factoredmarcher). Changed the "eikonal.distance" function to use an index-vector as source x_s instead of a real-valued vector.
0.9.4
Reverted from "size_t" and "ptrdiff_t" back to "unsigned long" and "long", since it introduced some multi-platform problems.
0.9.0
This should already be a fully working version. I just want to do further testing on different machines to officially release v1.0.0.
