This version is a major release, with many new features and improvements.

General changes

• C++17 Requirement: CGAL 6.0 requires a C++17 compatible compiler.
• GMP/MPFR Optional: GMP/MPFR are no longer mandatory; Boost.Multiprecision can be used.
• Qt6 Demos: All demos are now based on Qt6.
• Polyhedral Surface: The demo has been renamed to ΓÇ£CGAL LabΓÇ¥ and moved to its own directory in demo/Lab/.

New Packages

• Kinetic Space Partition: Partition of the space from planar input shapes.
• Kinetic Surface Reconstruction: Reconstructs surfaces from point clouds.
• Basic Viewer: Interactive visualization for various CGAL packages.
• Polygon Repair: Algorithms to repair 2D polygons and multipolygons.

Breaking Changes

• CMake Changes: UseCGAL.cmake removed; use CGAL::CGAL target instead.
• Kernel: Replaced boost::variant with std::variant and boost::optional with std::optional in the intersection functions.

Enhancements

• AABB Tree: Now supports 2D and 3D primitives.
