+CGAL 6.0 offers the following improvements and new functionality over
+CGAL 5.6:
+
+
+
+## Changelog
+
+### General Changes
+
+- CGAL 6.0 is the first release of CGAL that requires a C++ compiler
+ with the support of C++17 or later. The new list of supported compilers is:
+ - Visual C++ 15.9, 16.10, 17.0 (from Visual Studio 2017, 2019 and 2022) or later
+ - Gnu g++ 11.4.0 or later (on Linux or macOS)
+ - LLVM Clang version 15.0.7 or later (on Linux)
+ - Apple Clang compiler versions 10.0.1, 12.0.5, and 15.0.0 (on macOS)
+- The minimal supported version of Boost is now 1.72.0.
+- GMP/MPFR are no longer mandatory to use CGAL, [Boost.Multiprecision](https://www.boost.org/doc/libs/1_72_0/libs/multiprecision/doc/html/index.html).
+ can be used instead.
+- The CGAL `Core` library is no longer based on GMP, but on
+ [Boost.Multiprecision](https://www.boost.org/doc/libs/1_72_0/libs/multiprecision/doc/html/index.html).
+ Either GMP backend or Boost backend can be used.
+- All demos are now based on Qt6.
+- **Breaking change**: The CMake file `UseCGAL.cmake` has been removed from CGAL.
+ Usages of the CMake variables `${CGAL_USE_FILE}` and `${CGAL_LIBRARIES}` must be replaced
+ by a link to the imported target `CGAL::CGAL`, for example:
+ `target_link_library(your_target PRIVATE CGAL::CGAL)`.
+
+### [Kinetic Space Partition](https://doc.cgal.org/6.0/Manual/packages.html#PkgKineticSpacePartition) (new package)
+
+- This package implements kinetic space partition: based on a set of planar input shapes,
+ the bounding box of the input data is split into convex volumes. The complexity of the partition
+ can be adjusted with a single parameter.
+
+### [Kinetic Surface Reconstruction](https://doc.cgal.org/6.0/Manual/packages.html#PkgKineticSurfaceReconstruction) (new package)
+
+- The package implements a piece-wise planar surface reconstruction pipeline from point clouds
+ combining methods from the [Shape Detection](https://doc.cgal.org/6.0/Manual/packages.html#PkgShapeDetection),
+ [Shape Regularization](https://doc.cgal.org/6.0/Manual/packages.html#PkgShapeRegularization)
+ and [Kinetic Shape Partition](https://doc.cgal.org/6.0/Manual/packages.html#PkgKineticSpacePartition) packages
+ and graph-cut to reconstruct surfaces from point clouds.
+
+### [Basic Viewer](https://doc.cgal.org/6.0/Basic_viewer/index.html#Chapter_Basic_viewer) (new package)
+
+- The basic viewer package provides interactive visualization for most CGAL packages,
+ such as [2D Arrangements](https://doc.cgal.org/6.0/Manual/packages.html#PkgArrangementOnSurface2),
+ [2D Regularized Boolean Set-Operations](https://doc.cgal.org/6.0/Manual/packages.html#PkgBooleanSetOperations2),
+ [Linear Cell Complex](https://doc.cgal.org/6.0/Manual/packages.html#PkgLinearCellComplex),
+ [3D Boolean Operations on Nef Polyhedra](https://doc.cgal.org/6.0/Manual/packages.html#PkgNef3),
+ [2D Periodic Triangulations](https://doc.cgal.org/6.0/Manual/packages.html#PkgPeriodic2Triangulation2),
+ [3D Point Set](https://doc.cgal.org/6.0/Manual/packages.html#PkgPointSet3),
+ [2D Polygons](https://doc.cgal.org/6.0/Manual/packages.html#PkgPolygon2),
+ [3D Polyhedral Surface](https://doc.cgal.org/6.0/Manual/packages.html#PkgPolyhedron),
+ [2D Straight Skeleton and Polygon Offsetting](https://doc.cgal.org/6.0/Manual/packages.html#PkgStraightSkeleton2),
+ [Surface Mesh](https://doc.cgal.org/6.0/Manual/packages.html#PkgSurfaceMesh),
+ [2D Triangulations](https://doc.cgal.org/6.0/Manual/packages.html#PkgTriangulation2),
+ [3D Triangulations](https://doc.cgal.org/6.0/Manual/packages.html#PkgTriangulation3),
+ [2D Voronoi Diagrams](https://doc.cgal.org/6.0/Manual/packages.html#PkgVoronoiDiagram2),
+ and more.
+ The most simple use case of the basic viewer is the call of the global `CGAL::draw()` function.
+ There is one such `draw()` function for each CGAL package that has a basic viewer. Such a call opens
+ an interactive window showing the given model and allowing to navigate in the scene,
+ show or hide some specific cells, show the interior of the model if any, etc.
+ The `Basic_viewer` is based on Qt6.
+
+### [Polygon Repair](https://doc.cgal.org/6.0/Manual/packages.html#PkgPolygonRepair) (new package)
+
+- This package provides algorithms to repair 2D polygons, polygons with holes,
+ and multipolygons with holes, by selecting faces of the arrangement of the input
+ using the odd-even heuristic.
+
+### [2D and 3D Linear Geometry Kernel](https://doc.cgal.org/6.0/Manual/packages.html#PkgKernel23)
+
+- **Breaking change**: Replaced all instances of `boost::variant` with `std::variant`
+ in the intersection functions.
+- **Breaking change**: Replaced all instances of `boost::optional` with `std::optional`
+ in the intersection functions.
+
+### [3D Polyhedral Surface](https://doc.cgal.org/6.0/Manual/packages.html#PkgPolyhedron)
+
+- The demo of this package, also known as "Polyhedron Demo" has been renamed "CGAL Lab"
+ and moved to its own package ("Lab").
+
+### [2D and 3D Fast Intersection and Distance Computation (AABB Tree)](https://doc.cgal.org/6.0/Manual/packages.html#PkgAABBTree)
+
+- The AABB tree can now be used with 2D or 3D primitives:
+ - The concepts `AABBGeomTraits` and `AABBRayIntersectionGeomTraits`
+ have been replaced by [`AABBGeomTraits_3`](https://doc.cgal.org/6.0/AABB_tree/classAABBGeomTraits__3.html)
+ and by [`AABBRayIntersectionGeomTraits_3`](https://doc.cgal.org/6.0/AABB_tree/classAABBRayIntersectionGeomTraits__3.html),
+ respectively.
+ - The concepts [`AABBGeomTraits_2`](https://doc.cgal.org/6.0/AABB_tree/classAABBGeomTraits__2.html)
+ and [`AABBRayIntersectionGeomTraits_2`](https://doc.cgal.org/6.0/AABB_tree/classAABBRayIntersectionGeomTraits__2.html)
+ have been introduced, as the 2D counterparts.
+ - The class [`CGAL::AABB_traits`](https://doc.cgal.org/6.0/AABB_tree/group__PkgAABBTreeRef.html#ga764f0fc59c96355877536810aa1aca5b)
+ is deprecated and replaced by [`CGAL::AABB_traits_3`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__traits__3.html).
+ - The class [`CGAL::AABB_traits_2`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__traits__2.html) is introduced as the 2D counterpart.
+ - The class [`CGAL::AABB_segment_primitive`](https://doc.cgal.org/6.0/AABB_tree/group__PkgAABBTreeRef.html#gad0acfd5c4a3c081b7570cc6bd4594c8d)
+ has been deprecated and replaced by the class [`CGAL::AABB_segment_primitive_3`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__segment__primitive__3.html).
+ - The class [`CGAL::AABB_triangle_primitive`](https://doc.cgal.org/6.0/AABB_tree/group__PkgAABBTreeRef.html#ga54a56f01dc8024624f7d83ee0a01add0)
+ has been deprecated and replaced by the class [`CGAL::AABB_triangle_primitive_3`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__triangle__primitive__3.html).
+ - The following 2D primitive classes have been added:
+ [`CGAL::AABB_segment_primitive_2`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__segment__primitive__2.html),
+ [`CGAL::AABB_polyline_segment_primitive_2`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__polyline__segment__primitive__2.html),
+ [`CGAL::AABB_triangle_primitive_2`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__triangle__primitive__2.html),
+ [`CGAL::AABB_indexed_triangle_primitive_2`](https://doc.cgal.org/6.0/AABB_tree/classCGAL_1_1AABB__indexed__triangle__primitive__2.html).
+- **Breaking change**: The concept [`AABBTraits`](https://doc.cgal.org/6.0/AABB_tree/classAABBTraits.html)
+ now refines the concept [`SearchTraits`](https://doc.cgal.org/6.0/Spatial_searching/classSearchTraits.html).
+- **Breaking change**: Replaced all instances of `boost::optional` with `std::optional`.
+
+### [2D Arrangements](https://doc.cgal.org/6.0/Manual/packages.html#PkgArrangementOnSurface2)
+
+- **Breaking change**: Replaced all instances of `boost::variant` with `std::variant`.
+- **Breaking change**: The type of the result of point location queries has been changed to
+ `std::variant`. Support for the old macro `CGAL_ARR_POINT_LOCATION_VERSION`
+ has been removed.
+- **Breaking change**: Eliminated the error-prone C-type casting that was used to define observers.
+ In general, backward compatibility was maintained; however, the class template
+ [`CGAL::Arr_observer`](https://doc.cgal.org/6.0/Arrangement_on_surface_2/group__PkgArrangementOnSurface2Ref.html#ga8019f986f5469920136c4b92290b7b1b)
+ has been replaced by an alias template. (The class `CGAL::Arr_observer`
+ was renamed to [`CGAL::Aos_observer`](https://doc.cgal.org/6.0/Arrangement_on_surface_2/classCGAL_1_1Aos__observer.html)).
+- Introduced [`Arr_dcel`](https://doc.cgal.org/6.0/Arrangement_on_surface_2/classCGAL_1_1Arr__dcel.html),
+ which essentially replaces the former `CGAL::Arr_default_dcel`.
+ Backward compatibility was maintained by the introduction of the alias template
+ [`CGAL::Arr_default_dcel`](https://doc.cgal.org/6.0/Arrangement_on_surface_2/group__PkgArrangementOnSurface2DCEL.html#gaf9635869a3794a46d7dcfce63d7de2a6).
+ `CGAL::Arr_dcel`, as opposed to the former `CGAL::Arr_default_dcel` is templated
+ (in addition to the geometry traits) by `Vertex`, `Halfedge`, and `Face` template parameters,
+ and they have default type values. All this enables the layered extension of DCEL records.
+- Fixed a bug in the zone construction code applied to arrangements of geodesic arcs on a sphere,
+ when inserting an arc that lies on the identification curve.
+- Introduced a new interactive program that demonstrates 2D arrangements embedded on the sphere
+ called `earth`. The program (i) reads a database of all administrative boundaries of the countries
+ in the world, (ii) displays the globe with all countries and land covered by water (which is land
+ not covered by countries) on a window, and (ii) enables interaction with the user.
+
+### [3D Envelopes](https://doc.cgal.org/6.0/Manual/packages.html#PkgEnvelope3)
+
+- **Breaking change**: [`Construct_projected_boundary_2`](https://doc.cgal.org/6.0/Envelope_3/classEnvelopeTraits__3.html#ac7b8f72870f0572834a0a3de62c67bc1)
+ in [`EnvelopeTraits_3`](https://doc.cgal.org/6.0/Envelope_3/classEnvelopeTraits__3.html)
+ now uses `std::variant` instead of [`CGAL::Object`](https://doc.cgal.org/6.0/STL_Extension/classCGAL_1_1Object.html).
+- Passed the base class of [`CGAL::Env_plane_traits_3`](https://doc.cgal.org/6.0/Envelope_3/classCGAL_1_1Env__plane__traits__3.html)
+ as a template parameter with a default value (being the 2D arrangement linear traits).
+ Similarly, passed the base class of `CGAL::Env_triangle_traits_3` as a template parameter
+ with a default value (being the 2D arrangement segment traits).
+
+### [Combinatorial Maps](https://doc.cgal.org/6.0/Manual/packages.html#PkgCombinatorialMaps) and [Generalized Maps](https://doc.cgal.org/6.0/Manual/packages.html#PkgGeneralizedMaps)
+
+- Added the function [`insert_cell_1_between_two_cells_2()`](https://doc.cgal.org/6.0/Combinatorial_map/classGenericMap.html#aa29570a0812094c7876e24a228373f12)
+ to the [`GenericMap`](https://doc.cgal.org/6.0/Combinatorial_map/classGenericMap.html)
+ concept, which enables users to insert an edge between two different faces in order to create faces with holes.
+
+### [Quadtrees, Octrees, and Orthtrees](https://doc.cgal.org/6.0/Manual/packages.html#PkgOrthtree)
+
+- **Breaking change**:
+ - Node splitting behavior and per-node data are now customizable via the Traits class.
+ - Nodes are now stored as a property map, with properties of each node accessed by index.
+ - Nearest neighbors functions only work for Orthtrees which provide the necessary functionality.
+
+### [CGAL and the Boost Graph Library (BGL)](https://doc.cgal.org/6.0/Manual/packages.html#PkgBGL)
+
+- Added the function [`CGAL::remove_all_elements()`](https://doc.cgal.org/6.0/BGL/group__PkgBGLHelperFct.html#gac7e199820c95ed1fc6ab536750749358),
+ which removes vertices, halfedges, and faces without collecting garbage and without removing properties.
+- [Dynamic property maps](https://doc.cgal.org/6.0/BGL/group__PkgBGLPropertiesDynamic.html)
+ can now have a default value.
+- The class [`CGAL::Face_filtered_graph`](https://doc.cgal.org/6.0/BGL/structCGAL_1_1Face__filtered__graph.html)
+ now supports patch IDs of any type and not just `faces_size_type`. The only requirement is that
+ the type is hashable.
+
+### [Polygon Mesh Processing](https://doc.cgal.org/6.0/Manual/packages.html#PkgPolygonMeshProcessing)
+
+- Added the function [`CGAL::Polygon_mesh_processing::autorefine_triangle_soup()`](https://doc.cgal.org/6.0/Polygon_mesh_processing/group__PMP__corefinement__grp.html#gaec85370aa0b2acc0919e5f8406cfb74c),
+ which can be used to refine a soup of triangles such that no pair of triangles intersects
+ in their interiors. Also added, the function [`CGAL::Polygon_mesh_processing::autorefine()`](https://doc.cgal.org/6.0/Polygon_mesh_processing/group__PMP__corefinement__grp.html#ga3e3a0a82b6c04bdc3a6c070e8da4aed5)
+ operating directly on a triangle mesh and updating it using the aforementioned function on a triangle soup.
+- Added the class [`CGAL::Corefinement::Non_manifold_output_visitor`](https://doc.cgal.org/6.0/Polygon_mesh_processing/structCGAL_1_1Polygon__mesh__processing_1_1Corefinement_1_1Non__manifold__output__visitor.html),
+ which can be used in corefinement based functions to deal with non-manifold outputs.
+- Added the option to use a variable sizing field for [`CGAL::Polygon_mesh_processing::isotropic_remeshing()`](https://doc.cgal.org/6.0/Polygon_mesh_processing/group__PMP__meshing__grp.html#ga66cb01cf228ed22f0a2a474cfa2aeb3f),
+ and a sizing function based on a measure of local curvature for adaptive remeshing.
+- Added the function [`CGAL::Polygon_mesh_processing::interpolated_corrected_curvatures()`](https://doc.cgal.org/6.0/Polygon_mesh_processing/group__PMP__corrected__curvatures__grp.html#ga22665c9ce92aaedab07df1b05f20bdb2)
+ which can be used to compute the mean and Gaussian curvatures, as well as the principal curvature
+ and directions.
+- Added the function [`CGAL::Polygon_mesh_processing::refine_mesh_at_isolevel()`](https://doc.cgal.org/6.0/Polygon_mesh_processing/group__PkgPolygonMeshProcessingRef.html#ga396505d5a60b5f6d29792b214fa59352)
+ which can be used to refine a polygon mesh along an isocurve.
+- Added the function [`CGAL::Polygon_mesh_processing::add_bbox()`](https://doc.cgal.org/6.0/Polygon_mesh_processing/group__PkgPolygonMeshProcessingRef.html#gabaf98d2fd9ae599ff1f3a5a6cde79cf3),
+ which enables adding a tight or extended, triangulated or not, bounding box to a face graph.
+
+### [2D Triangulations](https://doc.cgal.org/6.0/Manual/packages.html#PkgTriangulation2)
+- **Breaking change**: the concept [`TriangulationTraits_2`](https://doc.cgal.org/6.0/Triangulation_2/classTriangulationTraits__2.html) now requires an additional functor `Compare_xy_2`.
+
+### [3D Triangulations](https://doc.cgal.org/6.0/Manual/packages.html#PkgTriangulation3)
+
+- Added three member functions [`vertices()`](https://doc.cgal.org/6.0/Triangulation_3/classCGAL_1_1Triangulation__3.html#a02faf334255e1ca8caa1a6f412533759)
+ to the class [`CGAL::Triangulation_3`](https://doc.cgal.org/6.0/Triangulation_3/classCGAL_1_1Triangulation__3.html).
+ Each of them returns an array containing the vertices of the given triangulation simplex.
+
+### [dD Triangulations](https://doc.cgal.org/6.0/Manual/packages.html#PkgTriangulations)
+
+- **Breaking change**: `CGAL::TDS_full_cell_mirror_storage_policy` is now unsupported in dimension larger than 127.
+- **Breaking change**: Inserting multiple unweighted points in the same
+ position now keeps the first one, instead of switching to the latest. This
+ only affects custom point types where not all points in the same position
+ are equivalent.
+
+### [Tetrahedral Remeshing](https://doc.cgal.org/6.0/Manual/packages.html#PkgTetrahedralRemeshing)
+
+- Added a sizing field as new parameter of [`CGAL::tetrahedral_isotropic_remeshing()`](https://doc.cgal.org/6.0/Tetrahedral_remeshing/group__PkgTetrahedralRemeshingRef.html#ga263775c52eeb483a86a16aeb9eb31af0),
+ which can be used to perform non-uniform and adaptive remeshing.
+- **Breaking change**: The template parameters of
+ [`CGAL::Tetrahedral_remeshing::Remeshing_cell_base_3`](https://doc.cgal.org/6.0/Tetrahedral_remeshing/classCGAL_1_1Tetrahedral__remeshing_1_1Remeshing__cell__base__3.html)
+ have been modified, reverting changes introduced in CGAL 5.6.
+- **Breaking change**: The vertex base of
+ [`CGAL::Tetrahedral_remeshing::Remeshing_vertex_base_3`](https://doc.cgal.org/6.0/Tetrahedral_remeshing/classCGAL_1_1Tetrahedral__remeshing_1_1Remeshing__vertex__base__3.html)
+ must now be a model of the concept
+ [`SimplicialMeshVertexBase_3`](https://doc.cgal.org/6.0/SMDS_3/classSimplicialMeshVertexBase__3.html)
+ (and not only [`TriangulationVertexBase_3`](https://doc.cgal.org/6.0/Triangulation_3/classTriangulationVertexBase__3.html)).
+
+### [3D Simplicial Mesh Data Structure](https://doc.cgal.org/6.0/Manual/packages.html#PkgSMDS3)
+
+- **Breaking change**: The template parameters of
+ [`CGAL::Simplicial_mesh_cell_base_3`](https://doc.cgal.org/6.0/SMDS_3/classCGAL_1_1Simplicial__mesh__cell__base__3.html)
+ have been modified to enable passing a geometric traits and a custom cell base class.
+
+### [3D Mesh Generation](https://doc.cgal.org/6.0/Manual/packages.html#PkgMesh3)
+
+- **Breaking change**: Removed the concept `TriangleAccessor`, the template parameter `TriangleAccessor`,
+ as well as the class `Triangle_accessor`. These were no longer used for several releases.
+- **Breaking change**: Removed the class templates `CGAL::Gray_image_mesh_domain_3`, `CGAL::Implicit_mesh_domain_3`,
+ and `CGAL::Labeled_image_mesh_domain_3`, which were deprecated since CGAL-4.13.
+- Added new meshing criterion `edge_distance`, an upper bound for the distance from the edge to the 1D feature.
+- **Breaking change**: the concept `MeshEdgeCriteria_3` was modified to include the new meshing criterion `edge_distance`.
+
+
+### [3D Surface Mesh Generation](https://doc.cgal.org/6.0/Manual/packages.html#PkgSurfaceMesher3)
+
+- This package is deprecated and the package [3D Mesh Generation](https://doc.cgal.org/6.0/Manual/packages.html#PkgMesh3) should
+ be used instead.
+
+### [Surface Mesh Parameterization](https://doc.cgal.org/6.0/Manual/packages.html#PkgSurfaceMeshParameterization)
+
+- **Breaking change**: The method [`CGAL::Surface_mesh_parameterization::LSCM_parameterizer_3`](https://doc.cgal.org/6.0/Surface_mesh_parameterization/classCGAL_1_1Surface__mesh__parameterization_1_1LSCM__parameterizer__3.html)
+ now requires the Eigen library.
