 ### [Polygon Mesh Processing](https://doc.cgal.org/6.2/Manual/packages.html#PkgPolygonMeshProcessing) (major changes)
 
+- **Breaking change**: Update the visitor concepts `PMPTriangulateFaceVisitor` and `PMPHolefillingVisitor` to request functions `accept_face()` and `accept_triangle()`, respectively. These functions can be used to tweak the way faces and holes are triangles by black listing some candidate triangles.
