# Change log for the `patch-image` package
## 0.3.2:
* Use package `dsp` instead of `hmatrix`
for the solution of the linear least squares problem
for determining absolute coordinates from image pair displacements.
This removes dependency from LAPACK and GSL
and makes the code a bit simpler.
## 0.3.1:
* Speed up computation by moving more stuff to Knead/LLVM.
## 0.3:
* Allow to save program state, modify it manually
and re-run with adapted parameters using CSV files.
## 0.2:
* Add new executable that is based on LLVM and `knead`.
* Add new algorithm for assembling the image from its parts.
The algorithm finds exactly matching part shapes,
such that the border of the shapes is where it hurts least visually.
## 0.1.0.2:
* Switch from `accelerate-fft` to `accelerate-cufft`.
## 0.1:
* Implement the patching algorithm using `accelerate-cuda`.
## 0.0:
* Tests for a weighting algorithm using `GeomAlgLib`.
The goal is to find a reasonable weighting
for mixing arbitrary overlapping polygons.
