-
New things:
- Add GEOSMinimumSpanningTree (Paul Ramsey)
- Add GEOSCoverageEdges (Paul Ramsey)
- Add new C API functions for Hausdorff distance (GH-1352, Sven Jensen)
- Add GEOSSubdivideByGrid (GH-1232, Dan Baston)
- Add support for curved geometries to the following operations:
- Add GEOSLineToCurve, GEOSCurveToLine (GH-1382, Dan Baston)
- Add GeometrySplitter (GH-1424, Dan Baston)
- Add progress reporting to GEOSCoverageSimplify, GEOSUnaryUnion (GH-1466, Even Rouault / Dan Baston)
-
Breaking Changes:
- BufferOp returns POLYGON EMPTY when fed Inf/Nan coords (GH-1332)
- Return Inf when calculating distance to an empty geometry (GH-1345, Even Rouault)
- Overlay operations now produce a LineString geometry in cases that would previously
produce a MultiLineString with contiguous sub-geometries. (GH-1459, Dan Baston)
-
Fixes/Improvements:
- Buffer of Linestring includes spurious hole (GH-1217, Moritz Kirmse)
- Preserve M values in GEOSInterpolate (GH-1390, Dan Baston)
- Preserve M values in GEOSLineMerge (GH-1364, Dan Baston)
- Preserve M values in GEOSCoverageSimplify (GH-1384, Paul Ramsey)
- Preserve M values in GEOSDensify (GH-1319, Dan Baston)
- Preserve M values in GEOSSimplify (GH-1317, Dan Baston)
- Preserve M values in GEOSPolygonize (GH-1363 Dan Baston)
- Fix some cases of dropped M values in overlay (GH-1364,GH-1388,GH-1407,GH-1408; Dan Baston)
- Support curved inputs in GEOSNode (GH-1347, Dan Baston)
- GEOSClusterDBSCAN fix unsassigned clusters with minPoints <= 1 (GH-1386, Dan Baston)
- Fix crash in GEOSConvexHull (GH-1358, Dan Baston)
- Overlay performance improvements (GH-1353, arriopolis, Martin Davis)
- Fix unintended ring rotation in Overlay results (GH-1412, Dan Baston)
