+- Rectify conflict dependencies (shlib transition from Nov 9 2015)
+  against old geos.
+- Update to release 3.10.3
+  * VoronoiDiagramBuilder::setSites(const CoordinateSequence&)
+    returns sorted output now
+  * Add SnappingNoder seeding
+  * Fix segfault in Hausdorff distance with empty geometries
+  * Fix inf loop in PolygonTriangulator
+  * Fix IsValidOp to handle repeated node points
+  * Fix IsSimpleOp to handle closed LineStrings with repeated
+    endpoints
+  * Fix crash in GeometryNoder on empty input
