完整改进记录：

Foundation Classes:

• 
  Using NULL as invalid pointer in Handle classes, instead of custom constant (0xfefd0000...);
  
  
• 
  STL-compatible iterators for classes in NCollection package;
  
  
• 
  Code clean-up: removing the usage of config.h, support of pre-standard STL streams, unused CDL template (“generic”) classes and instantiations, etc.;
  
  Modeling:
  
  
• 
  Data structures for Bounded Volume Hierarchy (BVH) algorithms;
  
  
• 
  Two new algorithms of global optimization in math used for Extrema;
  
  
• 
  Parallelization of Boolean Operations algorithm;
  
  
• 
  Interface to break execution of Boolean Operations algorithm;
  
  
• 
  Possibility to protect a shape against modification of geometry;
  
  
• 
  Refactoring and optimization of BRepMesh algorithm;
  
  
• 
  New option in 2d offset algorithm allowing to keep sharp corners and build one-side offset on an open wire;
  
  Visualization:
  
  
• 
  New component, VIS, providing interactive services (similar to AIS) for OCCT shapes in VTK viewer;
  
  
• 
  New approach for manipulations with views using a camera paradigm;
  
  
• 
  Support of stereoscopic display (requires a graphic card supporting OpenGL Quad Buffer);
  
  
• 
  Improved support of perspective views;
  
  
• 
  Ray tracing now uses shaders (GLSL) instead of OpenCL;
  
  
• 
  Possibility to combine objects drawn by OpenGL and ray tracing in one view;
  
  
• 
  Frustum culling for fast display of a large number of objects with high zoom;
  
  
• 
  Initial support for OpenGL ES 2.0 for mobile platforms;
  
  
• 
  New classes for display of colored shapes and point clouds in AIS;
  
  
• 
  Revised and completed implementation of connected interactive objects;
  
  
• 
  Improved handling of temporary objects in the viewer (immediate mode);
  
  Data Exchange:
  
  
• 
  Support of COMPSOLIDs in STEP export;
  
  
• 
  Support of UNICODE (UTF-8) filenames;
  
  
• 
  Support of names and attributes assigned to points (vertices) in XCAF;
  
  DRAW:
  
  
• 
  FPE signal handlers are disabled by default;
  
  
• 
  New sample scripts demonstrating modeling and visualization capabilities in DRAW;
  
  
• 
  Improved usability of top level menu (help browser, samples, User's Guide);
  
  Documentation:
  
  
• 
  New User's Guide describing Boolean Operations algorithms;
  
  
• 
  Improvement of extraction of class documentation for Reference Manual;
  
  Samples:
  
  
• 
  New sample for using drawing OCCT 3D viewer into Direct3D surface in WPF applications;
  
  Build system:
  
  
• 
  Support of building on Android (except for DRAW);
  
  Products:
  
  
• 
  New (experimental) mode in Express Mesh, allowing generation of all-quad meshes;
  
  
• 
  Universal interface to export mesh produced by Express Mesh;
  
  
• 
  Improved triangulation near face boundaries in Express Mesh (Delaunay meshing);
  
  
• 
  Update of training materials and samples;
  
  
• 
  Translation of HATCH entities from DXF;
  
  
• 
  Boolean operations on meshes in OMF provide history on elements and handle complex cases;
  
  
• 
  Visualization of meshes in OMF takes into account the direction of normal vectors to surface;
  
  
• 
  New wrapper for OCCT classes for Java language;
