+### New Features in Embree 2.12.0
+
+-   Added support for multi-segment motion blur for all primitive
+    types.
+-   API support for stream of pointers to single rays (rtcIntersect1Mp and
+    rtcOccluded1Mp)
+-   Improved BVH refitting performance for dynamic scenes.
+-   Improved high-quality mode for quads (added spatial split builder
+    for quads)
+-   Faster dynamic scenes for triangle and quad-based meshes on AVX2
+    enabled machines.
+-   Performance and correctness bugfix in optimization for streams of
+    coherent (single) rays.
+-   Fixed large memory consumption (issue introduced in Embree
+    v2.11.0). If you use Embree v2.11.0 please upgrade to Embree
+    v2.12.0.
+-   Reduced memory consumption for dynamic scenes containing small meshes.
+-   Added support to start and affinitize TBB worker threads by passing
+    "start_threads=1,set_affinity=1" to rtcNewDevice. These settings
+    are recommended on systems with a high thread count.
+-   rtcInterpolate2 can now be called within a displacement shader.
+-   Added initial support for Microsoft's Parallel Pattern Library (PPL) as
+    tasking system alternative (for optimial performance TBB is highly recommended).
+-   Updated to TBB 2017 which is released under the Apache v2.0
+    license.
+-   Dropped support for Visual Studio 2012 Win32 compiler. Visual
+    Studio 2012 x64 is still supported.
