(In other words, we round down from 0.5 not up when calculating the left edge or minimum x value of a strip of intersecting pixels) + +### :rocket: New Feature / Improvement +* Rigorous support for topologically "complex" geometries with overlapping holes or polygons. There is a small performance hit for geometries with holes or multiple polygons because of the new deconfliction/merging steps. + +### :bug: Bug Fix +* Fixed bug where the bounding box calculation for MultiPolygon geometries was sometimes only using the first polygon. +* Fixed bug whereby overlapping polygons or overlapping holes were misidentifying overlap as "inside" the polygon +* Fixed bug where sometimes No Data or NaN values were passed to the statistical calculations + +### :house: Internal + +* Replaced bespoke code for pulling polygons from a provided geometry with [mpoly](https://github.com/DanielJDufour/mpoly) +* Replaced bespoke bounding box calculation with [bbox-fns](https://github.com/danieljdufour/bbox-fns) +* Used [rasterstats](https://github.com/perrygeo/python-rasterstats) to generate "truth" test data. Results are now very similar to rasterstats, often identical. However, sometimes rasterstats and geoblaze will have results that are a few pixels different (representing less than 1% of pixels) for large complex areas. Further investigation is required. +* Use [write-image](https://github.com/danieljdufour/write-image) internally to visualize intersections, adding a manual visual way to check intersection calculations +* Use new version of [dufour-peyton-intersection](https://github.com/geotiff/dufour-peyton-intersection) + +### :memo: Documentation + +* No changes
