Kongsberg SIM is proud to release version 3.0.0 of the Coin 3D graphics library. Coin 3.0.0 is a major release. It breaks binary compatibility with previous versions of Coin, but is for the most part upward source code compatible with Coin 2.*. A new major release means it was time for doing cleanup-duties. Some dead-end developments were removed, certain ABI-preservation-related hacks were discarded and rewritten properly. Certain bad design choices were improved upon.
