• New OSPRay 'SDK'
• OSPRay internal headers are now installed, enabling applications
  to extend OSPRay from a binary install
• CMake macros for OSPRay and ISPC configuration now a part of
  binary releases
  - CMake clients use them by calling
  include(${OSPRAY_USE_FILE}) in their CMake code after
  calling find_package(ospray)
• New OSPRay C++ wrapper classes
  - These act as a thin layer on top of OSPRay object handles,
  where multiple wrappers will share the same underlying
  handle when assigned, copied, or moved
  - New OSPRay objects are only created when a class instance is
  explicity constructed
  - C++ users are encouraged to use these over the ospray.h
  API
• Complete rework of sample applications
• New shared code for parsing the commandline
• Save/load of transfer functions now handled through a separate
  library which does not depend on Qt
• Added ospCvtParaViewTfcn utility, which enables
  ospVolumeViewer to load color maps from ParaView
• GLUT based sample viewer updates
  - Rename of ospModelViewer to ospGlutViewer
  - GLUT viewer now supports volume rendering
  - Command mode with preliminary scripting capabilities,
  enabled by pressing ':' key (not available when using
  Intel C++ compiler (icc))
• Enhanced support of sample applications on Windows
• New minimum ISPC version is 1.9.0
• Support of Intel® AVX-512 for second generation Intel® Xeon Phi™
  processor (codename Knights Landing) is now a part of the
  OSPRAY_BUILD_ISA CMake build configuration

• Enhanced error messages when ospLoadModule() fails
• Added OSP_FB_RGBA32F support in the DistributedFrameBuffer
• Updated Glass shader in the PathTracer
