NAME
       coin400 - New Features in Coin v4.0.0

       Kongsberg Oil & Gas Technologies AS ended Coin as a commercial product
       and re-licensed it under the BSD 3-clause license as a service to the
       user community.

       The build system has been migrated from GNU Autotools to CMake.

       This is a brief summary of the new features in Coin v4.0.0:

       o Support for UNICODE text (starting with Coin 4.0 strings are UTF-8
         encoded).

       o View volume and projectors now support reverse perspective camera
         settings

       o New SoReversePerspectiveCamera node added

       o New getRadius method added to SoRayPickAction

       o New virtual method getPickedPointForStart added to SoDragger to allow
         dragging of (partially) covered objects by derived draggers

       o New greater than and less than operators added to SbString

       o Implemented SoTextureCoordinateObject for linear texture functions

       o New SoAlphaTest node added

       o Support for GLSL/ARB shaders has been added to
         SoShaderStateMatrixParameter

       o Support for linePatternScaleFactor in SoDrawStyle

       o Support for newer compilers

       o Support for DISABLE policy in SoSelection node

       o API changes in SbMatrix, SoPickAction, SoEvent, SoSFTime, SbPList to
         improve conformance to Open Inventor 2.1 API

       o Created public API for converting geo coordinates

       o Auto-linking to the Coin library when using Microsoft Visual C++
         compilers

       o Updated expat sources to version 2.2.6

       o Removed local Boost includes. Added configure option --with-boost

       o Support for BitBucket and AppVeyor as continuous integration service
         providers

       Bug fixes:

       o Engine output referencing

       o SoTextureCoordinatePlane rendering bug

       o Memory leak during SoDB cleanup

       o Memory leak in SoVertexAttribute

       o Wrong vertical offset used in SoOffscreenRenderer

       o Driver bug when allocating render-to-texture capable pbuffers from
         SoOffscreenRenderer

       o Incorrect normal binding for 3DS import

       o SoInteractionKit

       o SoRayPickAction incorrect matrix info in getViewVolume

       o SbTesselator triangulation errors

       o SoToVRML2Action handling of NurbsCurve and IndexedNurbsCurve

       o SoToVRML2Action handling TransformSeparator as Separator not Group

       o SoVRMLTransform transformation bug in getTranslationSpaceMatrix

       o SoVRMLExtrusion rendering

       o Numerous minor and major issues detected with static code analysis

       o Numerous documentation issues

       o Camera location is updated during interaction in SoDragger

       o Camera update handling in seek and spin modes

       o Bounding box center calculation of SoIndexedShape derived components

       o Intersection bounding box calculation between bounding box and view
         volume

       o Allow deletion of SoDraggers in callbacks

       o Crash in SoText2 when using non-integer font sizes

       o Out of bounds access to array in SoSceneTextureCubeMap

       o Numerical issues in computation of intersection between sphere and
         line

       o Numerical issue in SbDPMatrix::multLineMatrix()

       o Markers are disappearing when clipping planes are present

       o Set of invalid VRML identifier characters extended with '(', ')', and
         '|'

       o Replacement for OpenGL extensions string method, obsoleted since
         OpenGL version 3.0

       o Output of scenes containing SoGroup or derived nodes in SoWriteAction

       o Force setting color for all indices on TriangleStrips in
         SoMaterialBundle
