v2.5.0

Big Deals

• OpenGL → 4.1
• CGAL and its dependencies (GMP+MPFR) compile everywhere from source via cmake
• Github actions finish faster and rarely fail due to heap size
• Shadow mapping in viewer
• Fast inexact mesh-mesh intersections
• Robust isolines
• New tutorials
• Additional unit tests
• Loads of bug fixes
• comiso and serialization are on probation
