 - **Breaking change**: The usage of `boost::variant` has been replaced by `std::variant`. Packages affected are 2D Arrangements, and the Kernel intersection.
 - **Breaking change**: The file 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(the_target PRIVATE CGAL::CGAL)`.

+- **Breaking change**: The concept `AABBTraits` now should refine the `SearchTraits` concept.
+- The AABB tree is not working with 2D and 3D primitives:
+  - Replacement of `AABBGeomTraits` concept by `AABBGeomTraits_3` and `AABBRayIntersectionGeomTraits` by `AABBRayIntersectionGeomTraits_3`.
+  - Addition of `AABBGeomTraits_2` and `AABBRayIntersectionGeomTraits_2` concepts
+  - `AABB_traits` is deprecated and replaced by `AABB_traits_3`
+  - `AABB_segment_primitive` is deprecated and replaced by `AABB_segment_primitive_3`
+  - `AABB_triangle_primitive` is deprecated and replaced by `AABB_triangle_primitive_3`
+  - Addition of 2D primitive classes: `AABB_segment_primitive_2`, `AABB_triangle_primitive_2`, ...
