• New "scivis" renderer features
• Single sided lighting (enabled by default)
• Many new volume rendering specific features
  - Adaptive sampling to help improve the correctness of
  rendering high frequency volume data
  - Pre-integration of transfer function for higher fidelity
  images
  - Ambient occlusion
  - Volumes can cast shadows
  - Smooth shading in volumes
  - Single shading point option for accelerated shading
• Add preliminary support for adaptive accumulation in the MPI device
• Camera specific features
• Initial support for stereo rendering with the perspective camera
• Option architectural in perspective camera, rectifying
  vertical edges to appear parallel
• Rendering a subsection of the full view with
  imageStart/imageEnd supported by all cameras
• This will be our last release supporting the first generation Intel®
  Xeon Phi™ coprocessor (codename Knights Corner)
• Future major and minor releases will be upgraded to the latest
  version of Embree, which no longer supports Knights Corner
• Depending on user feedback, patch releases are still made to
  fix bugs
• Enhanced output statistics in ospBenchmark application
• Many fixes to the OSPRay SDK
• Improved CMake detection of compile-time enabled features
• Now distribute OSPRay configuration and ISPC CMake macros
• Improved SDK support on Windows
• OSPRay library can now be compiled with -Wall and -Wextra enabled
• Tested with GCC v5.3.1 and Clang v3.8
• Sample applications and modules have not been fixed yet, thus
  applications which build OSPRay as a CMake subproject should
  disable them with -DOSPRAY_ENABLE_APPS=OFF and
  -DOSPRAY_ENABLE_MODULES=OFF
• Minor bug fixes, improvements, and cleanups
• Regard shading normal when bump mapping
• Fix internal CMake naming inconsistencies in macros
• Fix missing API calls in C++ wrapper classes
• Fix crashes on MIC
• Fix thread count initialization bug with TBB
• CMake optimizations for faster configuration times
• Enhanced support for scripting in both ospGlutViewer and
  ospBenchmark applications
