 Added hyperspectral picture conversion to ra_tiff, with accurate
 color when targeting 16-bit/comp., LogLuv, and float utput,
 and the approximate method for 24-bit RGB.
+
+Taoning added genssky -L option to specify global and diffuse
+illuminance values for output calibration.
+
+Created C++ class for rcontrib and example tool rxcontrib, which
+is an optional compile in the src/rt directory.  The output
+model is more general in some respects and the operations more
+efficient, but standard output is not supported, nor is ASCII
+results data.
+
+Added experimental source-skipping method to rpict for scenes
+with large number of light sources.  Currently works with
+rcontrib and separate srcsamp image-processing tool.  Controlling
+rpict options are -dS for skip bitmap specification and -dC
+for correction coefficient image.  Compile using -DSSKIPOPT
+to include this option.
+
+Added strnstr.c compatibility module in ray/src/common, since
+it isn't present on Linux-derivatives.
+
+Added WGMDfunc material type with programmable roughness and
+separate modifier paths for the different components.
+
+Added gensurf -i option at the request of Peter Apian-Bennewitz
+to reverse surface normals, mostly for data input when it is
+a bit more difficult to adjust.
+
+Added rad -N option to rholo run for multiprocessing when
+mkillum and/or mkpmap are involved in octree prep.
