• Add support for multi-segment deformation motion blur for mesh
  geometry
• OSPRay now requires minimum Open VKL v1.2.0 to bring the following
  improvements:
  • Structured regular volumes support for cell-centered data via
    the cellCentered parameter (vertex-centered remains the
    default)
  • Particle volumes ignore particles with zero radius
• Add support for dynamic load balancing in MPI Offload device
• Support for photometric lights (e.g., IES or EULUMDAT) also for
  sphere and quad lights. When setting intensityDistribution,
  other values for intensityQuantity than
  OSP_INTENSITY_QUANTITY_SCALE are deprecated
• Changed CMake variables for enabling app categories:
  • OSPRAY_ENABLE_APPS_BENCHMARK replaces OSPRAY_APPS_BENCHMARK
  • OSPRAY_ENABLE_APPS_EXAMPLES replaces OSPRAY_APPS_EXAMPLES
  • OSPRAY_ENABLE_APPS_TUTORIALS replaces OSPRAY_APPS_TUTORIALS
  • OSPRAY_ENABLE_APPS_TESTING replaces OSPRAY_APPS_TESTING
• Improve sampling of quad lights in the pathtracer (solid angle
  instead of area)
• Instances can now have the group object rebound via a parameter
• Fix leaking framebuffers in the MPI Offload device
• Resolve possible race condition in assigning IDs to distributed
  objects in the MPI device
• Move ISPC module to modules/ folder and renamed the module to
  cpu
• Minimum version of rkcommon is 1.9.0, which brings the following
  improvements:
  • Add support for Intel oneAPI DPCPP compiler
  • Fix memory leak
